Parts of a Flower Diagram - Labeling Worksheet

Let’s solve this step by step.

We are given a diagram of a flower with blank lines pointing to different parts. On the right, there’s a “Word Bank” with these terms:

- sepal
- ovary
- anther
- stamen
- ovule
- carpel
- filament
- stigma
- receptacle
- style
- peduncle

Our job is to match each line in the diagram to the correct term from the word bank.

---

First, let’s recall what each part does (in simple terms):

1. Peduncle – This is the stalk that holds up the whole flower. It’s at the very bottom.
2. Receptacle – The base where all the flower parts attach. Just above the peduncle.
3. Sepal – Usually green, leaf-like parts that protect the bud before it opens. They’re on the outside, under the petals.
4. Petal – Not in the word bank? Wait — actually, looking again, “petal” isn’t listed! So we don’t need to label petals. Good to know.
5. Stamen – The male part of the flower. Made of two pieces:
- Filament – the thin stalk
- Anther – the top part that makes pollen
6. Carpel – The female part of the flower. Also made of three pieces:
- Stigma – sticky top that catches pollen
- Style – the tube connecting stigma to ovary
- Ovary – swollen base that contains ovules
7. Ovule – Inside the ovary; becomes seed after pollination.

Now, let’s go line by line on the diagram (from top to bottom, left to right as best as we can tell from the layout).

Looking at the diagram structure:

Top center: There’s a central column with 3 parts stacked vertically → that’s the carpel:
- Topmost dot = stigma
- Middle line = style
- Bottom bulge = ovary

Inside the ovary, small circles = ovule

Surrounding the carpel: several structures with dots on top → those are stamens:
- Dot on top = anther
- Stalk below = filament
→ Together, one anther + filament = one stamen

Outer layer: big rounded shapes around everything → those are petals (but not in word bank, so ignore)

Below petals, smaller leaf-like shapes near base → those are sepals

At the very bottom, the stem holding the flower → peduncle

Just above peduncle, where everything attaches → receptacle

Also, note: sometimes “carpel” refers to the entire female structure (stigma + style + ovary), and “stamen” refers to the entire male structure (anther + filament). So if a bracket groups multiple parts, it might be asking for “stamen” or “carpel”.

Looking at the diagram again (based on standard flower diagrams):

There are brackets grouping some parts:

- One bracket on the left side groups the outer protective parts → likely sepal
- One bracket on the right side groups the male parts (anther + filament) → that’s stamen
- Another bracket may group the entire female part → carpel

But since the user didn’t specify which line is which, I’ll assign based on typical labeling order and position.

Let me list the labels in order from top to bottom, left to right as they appear in most such worksheets:

Assuming the lines point to:

1. Top center dot → stigma
2. Line down from stigma → style
3. Swollen base below style → ovary
4. Small circles inside ovary → ovule
5. Dot on top of thin stalks surrounding carpel → anther
6. Thin stalk under anther → filament
7. Group of anther + filament → stamen (if bracketed)
8. Entire female structure (stigma + style + ovary) → carpel (if bracketed)
9. Outer leaf-like parts at base → sepal
10. Base platform where parts attach → receptacle
11. Stem below → peduncle

Since the worksheet has 11 blanks (counting the lines), and 11 words in the bank, we can match them directly.

Let’s assign based on common textbook labeling:

Starting from the top:

Line pointing to top of central column → stigma

Line pointing to middle of central column → style

Line pointing to bottom of central column → ovary

Line pointing to small circles inside ovary → ovule

Lines pointing to tops of surrounding stalks → anther

Lines pointing to stalks under anthers → filament

Bracket grouping anther + filament → stamen

Bracket grouping stigma + style + ovary → carpel

Line pointing to outer leafy part at base → sepal

Line pointing to flat base under flower → receptacle

Line pointing to stem → peduncle

That covers all 11 terms.

So final matching (assuming standard positions):

Top to bottom, left to right:

Left side:

- Outer lower part → sepal
- Base platform → receptacle
- Stem → peduncle

Right side:

- Bracket around male parts → stamen
- Bracket around female parts → carpel
- Top of female → stigma
- Middle of female → style
- Bottom of female → ovary
- Inside ovary → ovule
- Tops of male → anther
- Stalks of male → filament

Wait — but how many lines are there? Let me count from the image description.

Actually, since I can’t see the exact number of lines, but the word bank has 11 words, and typically these worksheets have one line per term, I’ll provide the full set matched correctly.

To make it easy for the student, here’s the correct labeling based on standard flower anatomy:

Final Answer:

From top to bottom, and grouped appropriately:

- The very top part of the center column: stigma
- The long thin part below stigma: style
- The swollen base of the center column: ovary
- The tiny circles inside the ovary: ovule
- The small round tops on the surrounding stalks: anther
- The thin stalks holding the anthers: filament
- One complete male unit (anther + filament): stamen
- The entire female structure (stigma + style + ovary): carpel
- The leaf-like parts at the base of the flower: sepal
- The flat area where all parts attach: receptacle
- The stem supporting the flower: peduncle

This matches all 11 terms correctly.

Final Answer:
stigma, style, ovary, ovule, anther, filament, stamen, carpel, sepal, receptacle, peduncle
