Photosynthesis process:

It is the process through which plants use the energy in sunlight to make their own food.

► Green plants use their leaves to collect sunlight and carbon dioxide from the air.
► Inside the green plant, sunlight allows carbon dioxide to combine with water to make
sugar, which gives the plant the energy it needs to grow.

► Give reasons:

Light is important for plant to grow
Because plants use light to make their own food, so the plant without light does not grow
well because it had less food.

-You leave a plant in a dark room for five days.
