BASIC NEEDS OF PLANTS

 PLANTS NEED AIR

Ø  Plants need oxygen from the air for respiration .

Ø  Plants also need carbon dioxide from the air to make food.

Ø  Plants make food through photosynthesis.

Ø  Plants will die without air.

PLANTS NEED WATER

Ø  Plants absorb water from the soil through their roots.

Ø  Plants need water for:

·         Making food during photosynthesis

·         Transporting food and minerals to the plant tissues

·         Keeping the plants cells turgid

PLANTS NEED SUNLIGHT

Ø Green plants can make their own food through photosynthesis.

Ø Sunlight is necessary for photosynthesis.Without sunlight plants will die.

Ø Green leaves contain chlorophyll to trap sunlight.

Ø Sunlight provides the energy needed or water to combine with carbon dioxide to produce glucose in the leaves.Oxygen is produced as a by-product.
