Question

All life owes its existence to chlorophyll. Give reason.

Answer 1

Chlorophyll is the green colouring matter found in plants. It is contained in microscopic cell organelles called chloroplasts. Chloroplasts are minute oval bodies bounded by a double membrane, and their interior contains closely packed flattened sacs (thylakoids) arranged in piles (grana) lying in a colourless ground substance called the stroma. Ordinarily, there may be 40-50 chloroplasts in a cell. The pigment chlorophyll converts light energy to chemical energy, carbohydrates in plants. This is the source of nutrition for all organisms on earth. Hence, all life owe their existence to chlorophyll.
