Plants Kingdom worksheet - Free Printable

Let’s go step by step to solve each part of the worksheet.

---

1. Complete the chart

We need to fill in missing Kingdom, Phylum, Class, or Species based on what we know about plant classification.

- Giant kelp: This is a type of brown algae. It belongs to:
- Kingdom: Protista (not Plantae — but sometimes grouped with plants in basic bio)
→ Wait! In many school curricula, giant kelp is placed under Plantae, phylum Phaeophyta.
But let’s check standard biology: Giant kelp = *Macrocystis pyrifera*, often classified under Protista in modern systems, but older texts put it in Plantae. Since this worksheet says “Plants Kingdom”, we’ll assume they want it under Plantae.
Actually — correction: Most current classifications place kelp in Protista, not Plantae. But since the title is “Plants Kingdom”, maybe they’re using an old system? Let’s look at other clues.

Wait — looking at row 5: “Basidiomycota” — that’s a fungus phylum! So this chart might be mixing kingdoms? That can’t be right for a “Plants Kingdom” worksheet.

Actually — Basidiomycota is fungi, not plants. So perhaps there’s a mistake? Or maybe the worksheet includes non-plants by accident?

But let’s proceed carefully.

Standard plant kingdom divisions:

- Non-vascular plants: Bryophyta (mosses)
- Vascular seedless: Pteridophyta (ferns)
- Gymnosperms: Conifers, cycads, etc.
- Angiosperms: Flowering plants → divided into Monocots and Dicots

Also, “Giant kelp” is not a true plant — it’s a protist. But if forced into Plantae, some old books put it in Phaeophyta.

“Shield fern” → definitely a fern → Pteridophyta

“Tulips” → flowering plant → Angiosperm → Monocotyledon

“Dicotyledon” → class under Angiosperms

“Gymnosperm” → phylum level? Actually, Gymnospermae is often treated as a division/phylum.

“Basidiomycota” → that’s fungi — so probably a trick or error? Maybe they meant something else? Or perhaps it’s testing if you know it’s not a plant?

Wait — maybe the chart has errors? Let’s try to fill logically.

Let me reconstruct:

Row 1: Species = Giant kelp → likely Phylum = Phaeophyta (if included), Class = ? (often no class specified), Kingdom = Protista — but worksheet says Plants Kingdom → conflict.

Perhaps in this context, they consider all photosynthetic organisms as “plants”? Unlikely.

Alternative approach: Maybe “Giant kelp” is mislisted? Or perhaps it’s referring to a different organism?

Actually — let’s skip and come back.

Row 2: Class = Dicotyledon → so Phylum should be Angiosperm, Kingdom = Plantae, Species = e.g., rose, oak, etc. — but blank. We can leave species blank or write example.

Row 3: Species = Shield fern → Phylum = Pteridophyta, Class = Filicopsida (or just leave blank), Kingdom = Plantae

Row 4: Phylum = Gymnosperm → Class = ? (e.g., Coniferopsida), Species = pine, spruce, etc.

Row 5: Phylum = Basidiomycota → this is FUNGI → Kingdom = Fungi, not Plantae. So either error, or they want us to note it’s not plant? But worksheet says “Plants Kingdom”. Hmm.

Perhaps it’s a typo and they meant “Bryophyta”? Because Basidiomycota doesn’t belong here.

Maybe “Basidiomycota” is meant to be “Anthophyta” or something? No.

Another idea: Perhaps the chart is not exclusively plants? But title says “Plants Kingdom”.

I think there might be an error in the worksheet. For educational purposes, I’ll assume “Basidiomycota” is a mistake and should be ignored or corrected. But since we have to fill, let’s say:

Kingdom: Fungi (but contradicts title) — better to skip or mark N/A.

Alternatively, perhaps they mean “Basidiospores” in plants? No.

Let’s look at row 6: Species = Tulips → Angiosperm, Monocotyledon.

So let’s fill what we can confidently:

| Kingdom | Phylum | Class | Species |
|---------|---------------|----------------|-------------|
| Plantae | Phaeophyta? | — | Giant kelp | ← problematic
| Plantae | Angiosperm | Dicotyledon | [example] |
| Plantae | Pteridophyta | — | Shield fern |
| Plantae | Gymnosperm | Coniferopsida? | Pine |
| Fungi | Basidiomycota | — | Mushroom | ← not plant
| Plantae | Angiosperm | Monocotyledon | Tulips |

This is messy. Perhaps for school level, they simplify:

Common simplified plant phyla:

1. Bryophyta (mosses)
2. Pteridophyta (ferns)
3. Gymnosperms
4. Angiosperms (with monocots/dicots)

Giant kelp is not typically included. Maybe they meant “kelp” as in seaweed, but still.

Another thought: In some contexts, "giant kelp" is listed under Chromista or Protista. I think for this worksheet, since it's titled "Plants Kingdom", and includes "Basidiomycota" which is fungi, there might be errors. But let's proceed with best guesses.

Perhaps "Giant kelp" is a distractor, and we should focus on clear ones.

Let me try to fill based on standard knowledge:

- Giant kelp: Not a plant → but if must, Kingdom: Protista, Phylum: Phaeophyta — but worksheet says Plants Kingdom → contradiction. Skip or put Plantae/Phaeophyta.

I recall that in some older systems, algae were included in Plantae. So:

Row 1: Kingdom: Plantae, Phylum: Phaeophyta, Class: — , Species: Giant kelp

Row 2: Kingdom: Plantae, Phylum: Angiosperm, Class: Dicotyledon, Species: e.g., Sunflower (but blank, so leave or write "various")

Row 3: Kingdom: Plantae, Phylum: Pteridophyta, Class: — , Species: Shield fern

Row 4: Kingdom: Plantae, Phylum: Gymnosperm, Class: — (or Coniferae), Species: e.g., Pine tree

Row 5: Phylum: Basidiomycota → this is fungi → Kingdom: Fungi, Class: — , Species: e.g., Button mushroom — but not plant. Perhaps the worksheet has a mistake. Maybe they meant "Bryophyta"? If so, Kingdom: Plantae, Phylum: Bryophyta, Class: — , Species: Moss

But it says "Basidiomycota", so I'll put Kingdom: Fungi, even though it contradicts title.

Row 6: Kingdom: Plantae, Phylum: Angiosperm, Class: Monocotyledon, Species: Tulips

For simplicity in school context, I'll fill as:

| Kingdom | Phylum | Class | Species |
|---------|---------------|----------------|-------------|
| Plantae | Algae | — | Giant kelp | ← approximate
| Plantae | Angiosperm | Dicotyledon | Rose | ← example
| Plantae | Pteridophyta | — | Shield fern |
| Plantae | Gymnosperm | — | Pine |
| Fungi | Basidiomycota | — | Mushroom | ← not plant
| Plantae | Angiosperm | Monocotyledon | Tulips |

But to match common curriculum, let's use:

- For Giant kelp: Some sources say Kingdom Plantae, Division Phaeophyta — so I'll go with that.

Final decision for chart:

1. Kingdom: Plantae, Phylum: Phaeophyta, Class: — , Species: Giant kelp
2. Kingdom: Plantae, Phylum: Angiosperm, Class: Dicotyledon, Species: [leave blank or "e.g., bean"] — but since blank, perhaps omit species or write "various dicots"
Better to leave species blank as per table.

Actually, the table has blanks, so we fill only where needed.

Looking back, the table has some cells already filled, we fill the empty ones.

Original table:

Row 1: Kingdom=?, Phylum=?, Class=------, Species=Giant kelp → so fill Kingdom and Phylum

Row 2: Kingdom=?, Phylum=?, Class=Dicotyledon, Species=? → fill Kingdom, Phylum, Species

Row 3: Kingdom=?, Phylum=?, Class=------, Species=Shield fern → fill Kingdom, Phylum

Row 4: Kingdom=?, Phylum=Gymnosperm, Class=?, Species=? → fill Kingdom, Class, Species

Row 5: Kingdom=?, Phylum=Basidiomycota, Class=?, Species=? → fill Kingdom, Class, Species

Row 6: Kingdom=?, Phylum=?, Class=?, Species=Tulips → fill Kingdom, Phylum, Class

Now, filling:

Row 1: Giant kelp → Kingdom: Plantae (assuming old system), Phylum: Phaeophyta
Row 2: Dicotyledon → Kingdom: Plantae, Phylum: Angiosperm, Species: e.g., Oak (but since not specified, perhaps "various" or leave — but better to put an example like "Rose")
Row 3: Shield fern → Kingdom: Plantae, Phylum: Pteridophyta
Row 4: Gymnosperm → Kingdom: Plantae, Class: Coniferopsida (or just "Conifers"), Species: Pine
Row 5: Basidiomycota → Kingdom: Fungi, Class: Basidiomycetes, Species: Agaricus (mushroom) — but not plant. Perhaps the worksheet intends this to be recognized as non-plant, but since it's in "Plants Kingdom" section, maybe error. I'll put Fungi.
Row 6: Tulips → Kingdom: Plantae, Phylum: Angiosperm, Class: Monocotyledon

So completed chart:

| Kingdom | Phylum | Class | Species |
|---------|---------------|----------------|-------------|
| Plantae | Phaeophyta | — | Giant kelp |
| Plantae | Angiosperm | Dicotyledon | Rose |
| Plantae | Pteridophyta | — | Shield fern |
| Plantae | Gymnosperm | Coniferopsida | Pine |
| Fungi | Basidiomycota | Basidiomycetes | Mushroom |
| Plantae | Angiosperm | Monocotyledon | Tulips |

Note: Row 5 is not a plant, but based on given data.

2. Write the letters to the correct place

Ferns, Gymnosperms, Angiosperms — match characteristics.

List:

a. have flowers and fruit → Angiosperm
b. woody cone → Gymnosperm (cones)
c. woody stem plants → could be both gymno and angio, but ferns are not woody usually. Ferns have rhizomes, not woody stems. So c might be for gymno/angio, but let's see.
d. have no flowers → Ferns and Gymnosperms
e. evergreen → Gymnosperms (many are)
f. soft and woody stem plants → Angiosperms (herbaceous and woody)
g. insects pollinated → Angiosperms (many)
h. reproduce by spores → Ferns
i. reproduce by seed → Gymnosperms and Angiosperms
j. wind pollinated → Gymnosperms (and some angiosperms, but primarily gymno)

Now assign:

Ferns:
- h. reproduce by spores
- d. have no flowers (since no flowers)
- also, ferns don't have seeds, cones, etc.

Gymnosperms:
- b. woody cone
- d. have no flowers
- e. evergreen (many)
- i. reproduce by seed
- j. wind pollinated

Angiosperms:
- a. have flowers and fruit
- f. soft and woody stem plants (diverse)
- g. insects pollinated (many)
- i. reproduce by seed (also)
- but i is shared, so perhaps list all that apply.

The instruction is "write the letters to the correct place", so probably multiple letters per group.

Typical assignments:

Ferns: h, d (and perhaps c? no, ferns not woody; f? no)

Standard:

Ferns: reproduce by spores (h), have no flowers (d)

Gymnosperms: woody cone (b), have no flowers (d), evergreen (e), reproduce by seed (i), wind pollinated (j)

Angiosperms: have flowers and fruit (a), soft and woody stem plants (f), insects pollinated (g), reproduce by seed (i) — but i is duplicate.

Since i is "reproduce by seed", it applies to both gymno and angio, so should be in both.

Similarly, d "have no flowers" applies to ferns and gymnosperms.

So:

Ferns: d, h
Gymnosperms: b, d, e, i, j
Angiosperms: a, f, g, i

But let's confirm:

- c. woody stem plants: this is vague. Ferns are not woody; gymnosperms and angiosperms can be. But perhaps not specific enough. Maybe omit or include in gymno/angio.

In many texts, "woody stem" is for trees/shrubs, which include gymno and angio, but ferns are herbaceous.

So c might be for gymno and angio, but since not specified, perhaps not assigned.

Similarly, f is "soft and woody stem plants" — angiosperms include herbs (soft) and trees (woody), so f for angiosperms.

I think:

Ferns: d, h
Gymnosperms: b, d, e, i, j
Angiosperms: a, f, g, i

Yes.

3. Put the words in the right order. The first is the less developed.

Words: spore, seed, cell division, fruit, rhizoid, flowers, rhizome, cell membrane, fruit (duplicate?)

List: spore, seed, cell division, fruit, rhizoid, flowers, rhizome, cell membrane, fruit — fruit appears twice? Probably typo.

Assume unique: spore, seed, cell division, fruit, rhizoid, flowers, rhizome, cell membrane

Order from less developed to more developed — meaning evolutionary complexity or structural complexity in plants.

Less developed: simplest structures.

Cell membrane — present in all cells, very basic.

Cell division — process, fundamental.

Rhizoid — root-like structure in mosses, simple.

Spore — reproductive unit in lower plants.

Rhizome — underground stem in ferns, more complex than rhizoid.

Seed — in gymnosperms/angiosperms, more advanced than spore.

Flowers — in angiosperms, most advanced reproductive structure.

Fruit — develops from flower, protects seed, most advanced.

So order:

Start with cellular level: cell membrane, cell division

Then simple plant structures: rhizoid (in bryophytes)

Then spore (reproduction in ferns, etc.)

Then rhizome (in pteridophytes)

Then seed (gymnosperms)

Then flowers (angiosperms)

Then fruit (angiosperms)

But cell division and cell membrane are not plant-specific structures; they are universal.

Perhaps the intent is plant evolutionary stages.

Typical order of plant evolution:

1. Algae (no true tissues) — but not listed

2. Bryophytes: rhizoids, spores

3. Pteridophytes: rhizomes, spores

4. Gymnosperms: seeds

5. Angiosperms: flowers, fruits

So:

Less developed: rhizoid (bryophytes) → spore (used in bryo and ptero) → rhizome (pteridophytes) → seed (gymno) → flowers (angio) → fruit (angio)

Cell division and cell membrane are too basic; perhaps not included or at start.

The list includes "cell division" and "cell membrane" — these are fundamental biological processes/structures, not specific to plant development stages.

Perhaps the question means order of appearance in plant evolution or complexity.

I think for school level, they might expect:

Start with spore (simple reproduction) → then seed → then flowers → then fruit

But rhizoid and rhizome are vegetative structures.

Perhaps:

rhizoid (simple anchor) → spore (reproduction) → rhizome (more complex stem) → seed → flowers → fruit

Cell division and cell membrane might be distractors or to be placed first.

Since "the first is the less developed", and cell membrane is most basic, then cell division, then rhizoid, etc.

But let's see the words: "spore, seed, cell division, fruit, rhizoid, flowers, rhizome, cell membrane, fruit" — fruit repeated, ignore one.

Proposed order:

1. cell membrane (most basic, present in all cells)

2. cell division (fundamental process)

3. rhizoid (simple root-like in mosses)

4. spore (reproductive cell in lower plants)

5. rhizome (underground stem in ferns)

6. seed (in seed plants)

7. flowers (in flowering plants)

8. fruit (mature ovary)

Yes, that makes sense.

So: cell membrane → cell division → rhizoid → spore → rhizome → seed → flowers → fruit

---

4. Write the Phylums of the Plants Kingdom in the right order. The first number is the less developed.

Phyla of Plantae, from least to most evolved:

Typically:

1. Bryophyta (mosses) — non-vascular

2. Pteridophyta (ferns) — vascular, no seeds

3. Gymnosperms — seeds, no flowers

4. Angiosperms — flowers and fruits

Sometimes algae are included, but usually not in strict Plantae.

So order: Bryophyta → Pteridophyta → Gymnosperms → Angiosperms

In the worksheet, it shows arrows: _ → _ → _ → _ → _

Five blanks? But usually four main groups.

Perhaps including Thallophyta (algae) or something.

Common sequence:

Thallophyta (algae) → Bryophyta → Pteridophyta → Gymnosperms → Angiosperms

Yes, five levels.

So:

Thallophyta → Bryophyta → Pteridophyta → Gymnosperms → Angiosperms

Some use Chlorophyta for green algae, but Thallophyta is traditional.

In modern terms, but for school, Thallophyta is fine.

So final answer for 4: Thallophyta, Bryophyta, Pteridophyta, Gymnosperms, Angiosperms

Now, compiling all answers.

For the chart, I'll write it clearly.

Since the user wants final answer after reasoning, I'll summarize.

Final Answer:

1. Completed chart:

| Kingdom | Phylum | Class | Species |
|---------|---------------|----------------|-------------|
| Plantae | Phaeophyta | — | Giant kelp |
| Plantae | Angiosperm | Dicotyledon | Rose |
| Plantae | Pteridophyta | — | Shield fern |
| Plantae | Gymnosperm | Coniferopsida | Pine |
| Fungi | Basidiomycota | Basidiomycetes | Mushroom |
| Plantae | Angiosperm | Monocotyledon | Tulips |

Note: Row 5 is not a plant, but based on given phylum.

2. Characteristics:

Ferns: d, h
Gymnosperms: b, d, e, i, j
Angiosperms: a, f, g, i

3. Order from less developed:
cell membrane → cell division → rhizoid → spore → rhizome → seed → flowers → fruit

4. Phyla order:
Thallophyta → Bryophyta → Pteridophyta → Gymnosperms → Angiosperms

Now, to box the final answer as per format.

Since it's multiple parts, I'll write them clearly.
