What are the adaptations of leaf for photosynthesis ?

Explanation

The adaptations of leaf for photosynthesis are :
(i) Surface area : leaves are flat and thin providing more surface area for exchange of gases and for maximum light absorption.
(ii) Position : least is help somewhat outwardly by the petiole so that it can came in contact with pure air and proper sinlight. They are arranged at right angles to the light source in a way that couses overlapping.
(iii) Veins and veinlets : The wide network of veins enables quick transport of substances to and from the mesophyll cells. The middle largest vein is midrib and others are simple small vein. They help in circulation up to the tip of leaf thus hekping in proper exchange of gases and supplying nutrients.
(iv) Chlorophyll : They contain a pigment for photosynthesis called chlorophyll which help in absorbing the light energy required.
(v) Presence of numerous stomata for gaseous excharge and transpiration.
(vi) Presence of lot of parenchyma means there is enough space for fodd storage.
(vii) Enzymes : verious enzymes required in the metabolic process of photosynthesis resides inside the leaf.
