Why do plants need these things.

In small groups, discuss why plants need water, warmth and air .

Explanation.

Plants need water so that they can have strong stems and be firm leaves. They also use water to transport substances such as food to all parts of the plant.
Most plants grow best when they get warmth. Most grow better if it is not too hot or too cold
Plants make their own food. They need light energy for this. A plant that does not get light energy grows long, thin stems, becomes weak and dies.
Plants are living things. Living things need air. Plants without air will die. Plants always grow towards the source of light energy.
