Q11. Match the seeds below to their features:

We are given three types of fruits (seed dispersal mechanisms) and three features. We need to match each type with its correct feature.

#### Given:
Type of fruit:
- Glider
- Parachute
- Shaker

Features:
- Openings at the top
- Stiff wings
- Light, fluffy parts

Now let’s analyze:

1. Glider – This refers to seeds that have stiff wings which help them glide through the air when they fall from the parent plant. Example: Maple seeds (helicopter seeds).
→ Glider → Stiff wings

2. Parachute – These seeds have light, fluffy parts (like fine hairs or feathery structures) that catch the wind and allow the seed to float away. Example: Dandelion seeds.
→ Parachute → Light, fluffy parts

3. Shaker – These fruits have openings at the top that release seeds when shaken by wind or animals. Example: Poppy or some pods that burst open.
→ Shaker → Openings at the top

✔ Final Matching:
- Glider → Stiff wings
- Parachute → Light, fluffy parts
- Shaker → Openings at the top

Q12. Label each of the stages in the life cycle of a dandelion plant:

We are given six images showing different stages in the life cycle of a dandelion. The labels to use are:
- Fertilisation
- Flowering
- Growth
- Pollination
- Germination
- Seed dispersal

Let’s go through the diagram clockwise (as indicated by arrows):

#### Step-by-step analysis:

1. Top left circle: A mature dandelion plant with a yellow flower.
→ This is Flowering.

2. Top right circle: A bee on the flower.
→ This shows Pollination (transfer of pollen by an insect).

3. Middle right circle: A close-up of a developing seed inside the ovary after pollination.
→ This is Fertilisation (the fusion of gametes to form a zygote).

4. Bottom right circle: A dandelion with white fluff (seed head), ready to blow away.
→ This is Seed dispersal.

5. Bottom left circle: A seed germinating in soil, with roots and shoot emerging.
→ This is Germination.

6. Middle left circle: A young plant growing in soil.
→ This is Growth.

Now label the boxes accordingly:

- Top left box: Flowering
- Top right box: Pollination
- Middle right box: Fertilisation
- Bottom right box: Seed dispersal
- Bottom left box: Germination
- Middle left box: Growth

✔ Final Answers:

#### Q11:
- Glider → Stiff wings
- Parachute → Light, fluffy parts
- Shaker → Openings at the top

#### Q12: Life Cycle Labels (clockwise from top left):
1. Flowering
2. Pollination
3. Fertilisation
4. Seed dispersal
5. Germination
6. Growth
