(i) Trap light energy and convert it to chemical energy’s for photolysis of water // carbon (IV)oxide fixation ;
(ii)Most chloroplast located in the palisade mesophyll which is nearer to the upper epidermis and thus exposed to more light // higher light intensity // optimum light intensity hence better rates // optimum photosynthesis.
(iii) Allows entry of carbon (IV) oxide; which combines with hydrogen atoms (from light stage)to form glucose.
