Note to Pupils:
Changes in Plants:
Plants go through different changes during their life cycle. These changes are essential for their growth and survival.
Some of these changes are;
– Leaf fall
- When the tree doesn’t need the leaves to make food anymore, it lets them go.
- This is a natural process to conserve energy during the winter months.
– Color of leaves
- Leaves are usually green because of a pigment called chlorophyll.
- In the fall, as the days get shorter and there is less sunlight, the chlorophyll breaks down. That’s why leaves change color.
– Flowers and fruits
- Flowers are an important part of a plant’s life cycle. They contain the reproductive parts of the plant.
- When a plant is ready to reproduce, it produces flowers with bright colors and sweet scents to attract pollinators like bees and butterflies.
Evaluation:
- Why do leaves fall from trees?
- Can you name a season when leaves often change color? Why?
- What is the purpose of flowers and fruits in plants?
