Phloem - Phloem transports products of photosynthesis (sugar and food) from the leaves where they are synthesized to other parts of the plant. It is made up of 4 types of elements - sieve tubes, companion cells, phloem fibres and the phloem parenchyma. Xylem transports water and minerals obtained through soil. Xylem consists of tracheids, vessels, xylem parenchyma and xylem fibres. Tracheids and vessels are tubular structures. These allow them to transport water and minerals vertically. The parenchyma stores food and helps in sideways conduction of water. Fibres are mainly supportive in function. Both phloem and xylem are known as conducting tissues. Therefore, water conducting channel in plants is xylem. Stomata are the tiny pores present on the surface of leaves. Exchange of gases takes place through these pores for the process of photosynthesis. These openings are surrounded by guard cells which, through changes in their size and shape, alter the size of stomatal openings and thus regulate the gas exchange. During transpiration, large amounts of water can be lost through these stomata. The plant closes its pores when it does not require CO2 for photosynthesis. The opening and closing of stomata is a function of guard cells. The guard cells swell when water flows through them causing the stomatal pore to open. Similarly, the pore closes if the guard cells shrink. Lenticels are the pores on the plant stem through which gaseous exchange takes place.
