Let's solve this step-by-step. The image is a worksheet about the structure of a flower, with a diagram to label and a word fill-in exercise.

🔹 Step 1: Understand the Diagram



The diagram shows a typical flower with its main parts labeled by lines pointing to various structures. Based on standard floral anatomy, here’s what each part should be:

#### 🌸 Key Flower Parts:
- Sepals – green leaf-like structures at the base (protects bud)
- Petals – colorful parts that attract pollinators
- Stamen – male reproductive organ
- Made up of:
- Anther – produces pollen (male gametes)
- Filament – supports the anther
- Pistil – female reproductive organ
- Made up of:
- Stigma – receives pollen
- Style – connects stigma to ovary
- Ovary – contains ovules (female gametes)

Now let’s label the diagram based on typical labeling order in such diagrams.

🔹 Labeling the Diagram (from top to bottom / left to right):



Assuming the arrows point to:

1. Top left petalPetal
2. Top right petalPetal
3. Outer curved structure below petalsSepal
4. Small oval structure on top of stamenAnther
5. Thin stalk supporting antherFilament
6. Tip of central structure (top)Stigma
7. Long tube connecting stigma to ovaryStyle
8. Bottom swollen part (central)Ovary
9. Structure inside ovary (small circles)Ovule

So, the labels are:

- Petal
- Petal
- Sepal
- Anther
- Filament
- Stigma
- Style
- Ovary
- Ovule

> ⚠️ Note: The diagram likely has multiple lines — you'll need to match them correctly. But based on common layouts, these are the correct terms.

🔹 Now, Complete the Word Fill Exercise



> "The male part of the flower is called the ____________ consists of the ____________ and ____________. The female part of the flower is called the ____________ consists of the ____________, ____________ and ____________. The male gamete is made in the ____________ and is found inside the ____________ grain. The female gamete is found in the ____________ and is called an ____________."

Let’s fill it in:

The male part of the flower is called the *stamen* consists of the *anther* and *filament*.
The female part of the flower is called the *pistil* consists of the *stigma*, *style* and *ovary*.
The male gamete is made in the *anther* and is found inside the *pollen* grain.
The female gamete is found in the *ovule* and is called an *ovum* (or egg).

Final Answer:



#### 📝 Diagram Labels (from top to bottom/left to right):
1. Petal
2. Petal
3. Sepal
4. Anther
5. Filament
6. Stigma
7. Style
8. Ovary
9. Ovule

*(Note: Exact placement depends on arrow direction, but these are the correct terms for those positions.)*

#### ✍️ Word Fill-in:

> The male part of the flower is called the stamen consists of the anther and filament. The female part of the flower is called the pistil consists of the stigma, style and ovary. The male gamete is made in the anther and is found inside the pollen grain. The female gamete is found in the ovule and is called an ovum.

---

🔍 Explanation:



- Stamen = male part → makes pollen (sperm cells).
- Pistil = female part → receives pollen and houses eggs.
- Anther = produces pollen grains (male gametes).
- Ovule = inside ovary → contains the female gamete (egg).
- Pollination occurs when pollen lands on the stigma, travels down the style, and fertilizes the ovule.

This completes both the labeling and the written exercise.
