Guard cells are adapted to their function of allowing gas exchange and controlling water loss within a leaf. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Hydrochloric acid plays a major role in the process of digestion. Guard cells (a) Control the size of the aperture. The structure of the leaf is adapted for gas exchange. A pair of guard cells surrounds the stoma. A. To support … Di tumbuhan dikotil seringkali banyak stomata atas epidermis bawah dibanding epidermis atas. The plant cuticle is an extracellular hydrophobic layer that covers the aerial epidermis of all land plants, providing protection against desiccation and external environmental stresses. Functions : Absorption of CO 2; Release of O 2 during day time. The remaining function of the light-dependent reaction is to generate the other energy-carrier molecule, NADPH. Its main function is conduction of water and mineral salts from root to the top of plant.Primary xylem elements originate from procambuim of apical meristem.Secondary xylem elements originate from the vascular cambium of lateral meristem. It's the skin. 5.0 4 votes 4 votes Rate! FUNCTION. 1 See answer ipbalbido14 is waiting for your help. Thus, the stomata help in the process of transpiration. The human body loses water in the form of sweat through the sweat pores in the skin. How relevant it is in photosynthesis? 5.0 2 votes 2 votes Rate! Likewise, if a plant is already dehydrated, it may close its stomata to prevent futher water loss. Remembering the function of chloroplasts, in which parts of the leaf is photosynthesis taking place. They can either be present on either the sides or just on one side of the leaf. They are surrounded by gaurd cells which help in closening and opening of stomata.
