Question

what is the adaptation of leaf for photosynthesis

Answer 1

Chlorophyll- they contain a pigment for photosynthesis called chlorophyll which help in absorbing the light energy required.

Surface area- leaves are flat and thin thus providing more surface area for exchange of gases.

Veins and veinlets- the middle largest vein is midrib and others are simply small veins. They help in circulation up to the tip of leaf thus helping in proper exchange of gases and supplying nutrients.

Position- leaf is held somewhat outwardly by the petiole so that it can come in contact with pure air and proper sunlight.

Enzymes- various enzymes required in the metabolic process of photosynthesis resides inside the leaf.

I hope this helped.

Thanks!

Answer 2

Adaptation of leaves for photosynthesis are : The adaptations of leaf for photosynthesis are: (i) Large surface area for maximum light absorption. (ii) The presence of chlorophyll containing chloroplast. (iii) The presence of numerous stomata on the surface for gaseous exchange.
