Educational worksheet for labeling the parts of a flower.

Let's solve this step-by-step by identifying and labeling the parts of the flower using the Word Box provided.

🔍 Step 1: Understand the Flower Structure

The image shows a typical flowering plant, with both male and female reproductive parts. We'll identify each labeled part based on its position and function.

---

🌸 Key Parts of a Flower:

#### ✔ Female Reproductive Part: Carpel
- Stigma: The top part that receives pollen.
- Style: The stalk connecting stigma to ovary.
- Ovary: The base, contains ovules (future seeds).
- Ovule: Inside the ovary; develops into seed after fertilization.

#### ♂️ Male Reproductive Part: Stamen
- Anther: Produces pollen.
- Filament: The stalk that holds the anther.

#### 🌿 Other Parts:
- Petal: Colorful part that attracts pollinators.
- Sepal: Green leaf-like structure at the base, protects the bud.
- Receptacle: The base of the flower where all parts attach.
- Stem: Supports the flower.
- Pollen tube: Grows from pollen grain down the style to deliver sperm to ovule.

🔧 Now, Match Each Label in the Diagram

We’ll go through each blank line and assign the correct term from the Word Box.

Let’s label them from left to right, top to bottom, following the lines:

---

📝 Final Labels (Based on Standard Flower Diagram):

1. Top-left line pointing to petal → Petal
2. Line below petal pointing to sepal → Sepal
3. Left side, middle line pointing to stem → Stem
4. Below stem, pointing to receptacle → Receptacle
5. Right side, top line pointing to anther → Anther
6. Next line down, pointing to filament → Filament
7. Next line, pointing to stigma → Stigma
8. Next line, pointing to style → Style
9. Next line, pointing to ovary → Ovary
10. Bottom-right line pointing to ovule → Ovule
11. Middle line pointing to carpel (entire female structure) → Carpel
12. Bottom-middle line pointing to pollen tube → Pollen tube

> Note: "Carpel" is the entire female structure (stigma + style + ovary). So the large central structure is labeled Carpel.

✔ Final Answer – Fill-in-the-Blanks:

Here’s how the blanks should be filled in order from the diagram:

| Line | Label |
|------|---------------|
| 1 | Petal |
| 2 | Sepal |
| 3 | Stem |
| 4 | Receptacle |
| 5 | Anther |
| 6 | Filament |
| 7 | Stigma |
| 8 | Style |
| 9 | Ovary |
| 10 | Ovule |
| 11 | Carpel |
| 12 | Pollen tube |

> ⚠️ Note: The word "Stamen" is not used directly in the labels because it's the combination of anther and filament. But since the diagram separates them, we label Anther and Filament individually.

---

💡 Summary:

- Stamen = Anther + Filament (male part)
- Carpel = Stigma + Style + Ovary (female part)
- Pollen tube grows from pollen grain down the style to reach the ovule
- Ovule becomes a seed after fertilization
