Photosynthesis

  • Plants make their food using sunlight, water, carbon dioxide and nutrients and minerals from the soil. This process is called photosynthesis.

 

  • Chlorophyll, a green color pigment, present in leaves helps plant in absorbing energy of light.

 

  • Plants leaves have small pores called as stomata. Each stoma is guarded by  2 sausage-shaped cells called as guard cells. Guard cells help in opening and closing of stoma.

 

  • Plant exchange gases through stomata. Stomata are found on the underside of leaves.

 

 

  • The process of photosynthesis occurs in leaves. Thus leaves are called kitchen of plants or food factory of plants.

 

  • Glucose, starch or food produced by photosynthesis is stored within the plant.

 

  • Oxygen is a by-product of photosynthesis.

 

  • Plant are green because their cell contains chloroplast which has green coloured pigment known as chlorophyll. Chlorophyll helps plant in absorbing energy of sunlight.
