The plant uses sugars produced during photosynthesis to builts its structure. * Petiole - the stalk that attaches the leaf to the stem. * Covering the upper and lower surfaces of the leaf is a transparent layer of cells called the epidermis which forms a waterproof coating‚ the cuticle. * Substances enter and leave the leaf by two routes: veins and stomates. * Photosynthesis occurs in the mesophyll cells that contain numerous chloroplasts. These mesophyll pile up to make

Plant Transport Plants are mostly made up of water. Lettuce is about 94% water and a potato is about 77% water. Plants need water for three main purposes: ------photosynthesis‚ -support -transport of chemicals Water is a raw material for photosynthesis. If water is in short supply‚ the rate of photosynthesis will be limited. Plants need water for support‚ otherwise they wilt. Water is needed to transport many chemicals within plants. Chemicals‚ such as mineral salts‚ dissolve in water and
