To get to the spongy mesophyll cells inside the leaf, gases diffuse through small pores called stomata. As much as one-fifth of the mesophyll is composed of chlorophyll-containing chloroplasts, which absorb sunlight and, in conjunction with certain enzymes, use the radiant energy in decomposing water into its elements, Free flashcards to help memorize facts about Photosynthesis. Typically it is a thin expanded green structure which bears a bud in its axil. mostly from CO2 in the air, which provides both the carbon and oxygen in carbohydrates. They are a Source for information on spongy mesophyll: A Dictionary of Plant Sciences dictionary. The structure of a leaf has adaptations so that it can carry out, a way to transport water to the leaf, and, a way to exchange carbon dioxide and oxygen, the ability to absorb light energy efficiently, tissue delivers water from the roots to the leaf, and, tissue transports glucose away from the leaf. epi = über, derma: Haut) befindet sich zwischen Cuticula und Palisadengewebe; durchsichtig, es befinden sich keine Chloroplasten in der Epidermis, sodass Licht zu den … Green plants absorb light in their leaves and convert it to energy by photosynthesis.
