Leaves contain chloroplasts located inside the leaf cells which have chlorophyll, a green pigment to capture light energy and use it to carry out photosynthesis. Leaf cells contain vacuoles, storage compartments to store water, or to store excess food that is produced. Sometimes, extra glucose can be converted to starch and stored elsewhere in a plant. For example, if the leaves of a plant produce extra glucose, some can be transported via phloem cells to be stored as starch above or underground in the fleshy stem or roots. These phloem cells are vascular tissue located in the veins, and along with xylem cells which conducts water from the soil up, function as a transport system in plants. In a desert environment, to reduce the loss of water by evaporation, plants have a fleshy stem to store water and the leaf surface is reduced to that of a needle. This cuts down on surface area and minimizes water loss. Also, there are less pores called stomates on these needles which reduces water loss. Desert plants have a waxy cuticle to protect the plant from dehydration.
i agree with the above ans..........but i think its matter with pressure flow theory..
