Answer:
Vascular Tissue- allows the transport of water, nutrients, and food between the ground and the body of the plant
a. Xylem- brings water and nutrients up from the roots to the rest of the plant; This tissue is dead at maturity
b. Phloem- carries glucose made during photosynthesis (predominately in the leaves) to the rest of the plant cells. This tissue is alive at maturity.
Explanation:
Xylem and phloem are two vascular tissues in plants. Their primary purpose is to transport different substances around the plant.
Xylem is mostly used to transport water and nutrients that it collects from the roots to fuel the rest of the plants, such as the leaves that require water for photosynthesis. The xylem needs to overcome the forces of gravity to transport substances around.
Phloem moves in the opposite direction, transporting sugar generated by photosynthesis to the non-photosynthesizing cells of the plants that still require energy. It simply works through diffusion as it does not need to overcome gravity.
