Parts of a Flower Worksheets - Free Printable - Free Printable

To label the parts of the flower correctly, we need to look at where each line points and match it with the correct term from the Word Box. Let’s go step by step.

First, let’s identify the main structures:

The female part of the flower is called the carpel (or pistil). It includes:
- The stigma — the sticky top part that catches pollen.
- The style — the long tube connecting stigma to ovary.
- The ovary — the bottom part that holds ovules and becomes fruit.
Inside the ovary are the ovules, which become seeds after fertilization.
Also, after pollination, a pollen tube grows down through the style to deliver sperm to the ovule.

The male part is called the stamen. Each stamen has:
- The anther — the yellow tip that makes pollen.
- The filament — the thin stalk holding up the anther.

Other parts:
- Petal — the colorful part that attracts insects.
- Sepal — the green leaf-like part under the petal that protects the bud.
- Receptacle — the base where all parts attach.
- Stem — supports the whole flower.

Now, let’s match the lines in the diagram (going clockwise from top left, then right side, then bottom):

Left side (from top to bottom):
1. Top-left line → points to the very top of the female structure → Stigma
2. Below that, two lines grouped together → point to the male parts:
- Upper one → Anther
- Lower one → Filament
Together, these make the Stamen (the big bracket on far left)
3. Bottom-left line → points to the green leaf under the petal → Sepal

Right side (from top to bottom):
4. Top-right line → points to the middle section of the female structure → Style
5. Next line down → points to the swollen base of the female structure → Ovary
6. Inside the ovary → small dots → Ovule
7. Line going into the ovary from above → Pollen tube
8. Big bracket on far right → groups stigma, style, ovary → this is the Carpel

Bottom center:
9. Line pointing to the flat base where everything attaches → Receptacle
10. Line pointing to the long support below → Stem

And don’t forget:
- The pink petals → Petal (line pointing to the pink part)

Let’s list them clearly based on position:

Starting from top-left and moving around:

Top-left single box → Stigma

Below that, two boxes connected to the same bracket (left side):
→ Upper: Anther
→ Lower: Filament
→ The big bracket enclosing those two: Stamen

Bottom-left box → Sepal

Top-right single box → Style

Next down on right → Ovary

Inside ovary → Ovule

Line entering ovary → Pollen tube

Big bracket on far right → Carpel

Center bottom → Receptacle

Very bottom → Stem

Pink petal area → Petal

Wait — we have 12 labels to fill? Let’s count the blank boxes in the image:

Looking at the diagram layout:

There are:
- Left column: 3 individual boxes + 1 big bracket = 4 items
- Right column: 5 individual boxes + 1 big bracket = 6 items
- Bottom row: 3 boxes

Total = 4 + 6 + 3 = 13? Wait, no — actually, looking again:

Actually, counting the ovals:

From top to bottom, left to right:

Left side:
1. Top oval (points to stigma)
2. Oval below it (points to anther)
3. Oval below that (points to filament)
4. Large vertical rectangle (bracket for stamen)

Right side:
5. Top oval (points to style)
6. Second oval (points to ovary)
7. Third oval (points to ovule inside ovary)
8. Fourth oval (points to pollen tube)
9. Fifth oval (points to receptacle? No — wait, let's reassign)

Actually, better to trace each line:

Let me assign numbers to each blank box as they appear visually:

Box A (top left) → points to stigma → Stigma

Box B (below A, left) → points to anther → Anther

Box C (below B, left) → points to filament → Filament

Box D (large vertical rectangle on far left) → brackets B and C → Stamen

Box E (bottom left) → points to sepal → Sepal

Box F (top right) → points to style → Style

Box G (second from top right) → points to ovary → Ovary

Box H (third from top right) → points to ovule → Ovule

Box I (fourth from top right) → points to pollen tube → Pollen tube

Box J (fifth from top right) → points to receptacle? Wait — no, the line from this box goes to the base of the flower, but not the stem — actually, looking again:

Wait — there’s also:

Box K (bottom center) → points to receptacle → Receptacle

Box L (bottom right) → points to stem → Stem

And Box M (pointing to petal) — yes, there’s a line from the pink petal to a box on the right side — actually, between Box G and H? Let me check original image description.

Actually, in standard diagrams like this, the petal is labeled too.

Looking back at user’s image description: there is a line pointing to the pink petal — so that must be one of the boxes.

In fact, counting all blanks:

There are 12 blank ovals/rectangles to fill.

List of terms in word box: 12 terms exactly.

So each term used once.

Terms: Sepal, Anther, Filament, Stamen, Stigma, Receptacle, Style, Ovary, Petal, Ovule, Carpel, Pollen tube, Stem — wait, that’s 13? No:

Word Box says:

Sepal
Anther
Filament
Stamen
Stigma
Receptacle
Style
Ovary
Petal
Ovule
Carpel
Pollen tube
Stem

That’s 13 terms? But only 12 blanks? Wait — let me recount the word box as written:

"Sepal, Anther, Filament, Stamen, Stigma, Receptacle, Style, Ovary, Petal, Ovule, Carpel, Pollen tube, Stem"

Yes, 13 words. But in the diagram, how many blanks?

Looking at the ASCII-style representation:

Left side:
- 3 ovals vertically
- 1 large rectangle (bracket)

Right side:
- 5 ovals vertically
- 1 large rectangle (bracket)

Bottom:
- 3 ovals horizontally

Total: 3+1 + 5+1 + 3 = 13 blanks? But some sources say 12.

Wait — perhaps the "Carpel" bracket includes multiple parts, and "Stamen" bracket includes two.

But in any case, we must use all terms appropriately.

Standard labeling:

Female reproductive part: Carpel (which consists of Stigma, Style, Ovary)

Male reproductive part: Stamen (consists of Anther, Filament)

Other: Petal, Sepal, Receptacle, Stem, Ovule, Pollen tube

So let’s map:

Assume the diagram has:

- One box for Stigma (top of carpel)
- One box for Style (middle of carpel)
- One box for Ovary (base of carpel)
- One box for Ovule (inside ovary)
- One box for Pollen tube (growing into ovary)
- One box for Carpel (bracket around stigma, style, ovary)

Similarly for male:
- One box for Anther
- One box for Filament
- One box for Stamen (bracket around anther and filament)

Then:
- Petal
- Sepal
- Receptacle
- Stem

That’s 12 items if we count the brackets as one each.

But in the word box, “Carpel” and “Stamen” are included, so we use them for the brackets.

Now, assigning to positions:

Based on common textbook diagrams:

Top-left box (pointing to top of central structure) → Stigma

Below it, two boxes on left:
- Upper → Anther
- Lower → Filament
Large bracket on far left enclosing those two → Stamen

Bottom-left box → Sepal

Top-right box → Style

Second from top right → Ovary

Third from top right → Ovule (inside ovary)

Fourth from top right → Pollen tube (entering ovary)

Fifth from top right → this might be pointing to the petal? Or receptacle?

Wait — there should be a box for Petal — likely pointing to the pink part.

In many such diagrams, the petal is labeled with a line from the pink area to a box on the right.

Similarly, Receptacle is the base, and Stem is below.

Also, the large bracket on the right encloses stigma, style, ovary → that’s the Carpel

So:

Far right large bracket → Carpel

Then the five boxes on right:

1. Points to style → Style
2. Points to ovary → Ovary
3. Points to ovule → Ovule
4. Points to pollen tube → Pollen tube
5. Points to... what? If there are five, perhaps one is for petal.

Actually, let's think differently. Perhaps the fifth box on right is for Petal.

And the bottom three:

Left-bottom → already assigned to sepal? No, bottom-left is sepal.

Bottom-center → Receptacle

Bottom-right → Stem

And the petal must be one of the right-side boxes.

Typically, the petal is labeled with a line from the pink part to a box on the right, often between style and ovary or something.

To resolve this, let's list all 13 terms and see which fits where.

Perhaps "Receptacle" is not always labeled separately, but here it is in the word box.

Another approach: look for the most obvious ones.

- The very top of the central column: Stigma
- The long neck below it: Style
- The bulbous base: Ovary
- Inside the ovary: Ovule
- The tube growing into ovary: Pollen tube
- The entire female structure bracketed: Carpel

For male:
- Yellow tips: Anther
- Stalks holding them: Filament
- Bracket around both: Stamen

Other:
- Pink parts: Petal
- Green leaves under petals: Sepal
- Base platform: Receptacle
- Support stalk: Stem

Now, in the diagram, there are 12 blanks? Or 13?

Counting the ovals in the user's description:

"Label the Parts of a Flower" diagram has:

- Left: 3 ovals + 1 rectangle = 4
- Right: 5 ovals + 1 rectangle = 6
- Bottom: 3 ovals = 3
Total: 4+6+3=13 blanks.

And word box has 13 terms. Perfect.

So all terms are used.

Now, assign:

Left side:

1. Top oval (points to top of carpel) → Stigma

2. Middle oval on left (points to anther) → Anther

3. Bottom oval on left (points to filament) → Filament

4. Large rectangle on far left (brackets 2 and 3) → Stamen

Right side:

5. Top oval on right (points to style) → Style

6. Second oval on right (points to ovary) → Ovary

7. Third oval on right (points to ovule inside ovary) → Ovule

8. Fourth oval on right (points to pollen tube entering ovary) → Pollen tube

9. Fifth oval on right — this must be pointing to the petal, since that's the only major part left unassigned on the right. In many diagrams, a line from the petal goes to a box on the right. So → Petal

10. Large rectangle on far right (brackets the entire female structure: stigma, style, ovary) → Carpel

Bottom row:

11. Left-bottom oval (points to sepal) → Sepal

12. Center-bottom oval (points to receptacle) → Receptacle

13. Right-bottom oval (points to stem) → Stem

Yes, that uses all 13 terms.

Confirm:

- Stigma: top of female part ✓
- Anther: male pollen producer ✓
- Filament: holds anther ✓
- Stamen: male part bracket ✓
- Style: connects stigma to ovary ✓
- Ovary: contains ovules ✓
- Ovule: becomes seed ✓
- Pollen tube: delivers sperm ✓
- Petal: attracts pollinators ✓
- Carpel: female part bracket ✓
- Sepal: protects bud ✓
- Receptacle: base attachment ✓
- Stem: support ✓

Perfect.

Final Answer:

Here is the correct labeling for each blank, based on the diagram's structure:

Left Side (top to bottom):
- Top oval: Stigma
- Middle oval: Anther
- Bottom oval: Filament
- Large vertical rectangle (bracket): Stamen

Right Side (top to bottom):
- Top oval: Style
- Second oval: Ovary
- Third oval: Ovule
- Fourth oval: Pollen tube
- Fifth oval: Petal
- Large vertical rectangle (bracket): Carpel

Bottom Row (left to right):
- Left oval: Sepal
- Center oval: Receptacle
- Right oval: Stem

This matches all parts correctly using every term from the Word Box exactly once.
