PARTS OF A PLANT AND THEIR FUNCTIONS

1. ROOTS

The part of the plant that remains under the ground is called the root. They also help to stop the soil erosion. They held the soil together. So, they stop the soil from getting washed away by water or blown away by the wind.They bring water to the upper parts of the plants. Roots take in minerals ans water from the soil and pass them to the centre of the root. They are then carried to all parts of the plant. Roots also give the plant support and keep it in position.


2. STEMS

3. LEAVES

The leaves are the food factories for the plant. They use carbondioxide, sunlight and water to make their food.



4. BUD

The bud grows into the flower.


5. FLOWER

Flowers are of many shapes, sizes and colours. Many flowers give fragrance too. They have bright colourful petals so that insects get attracted to them.The main function of a flower is to make  s eed. These seeds later become fruits.

6. FRUIT

A fruit grows from a flower.

7. SEEDS

The seeds when planted give another plant of the same type. All plants need seeds to grow. The seeds have a tiny baby plant inside them, which is protected by the seeds.
