What is xylem and phloem ? |
|
Answer» Xylem- It consists of\xa0tracheids, vessels, xylem parenchyma\xa0and\xa0xylem fibres.Tracheids and vessels are hollow tube-like structures that help in conducting water and minerals. The xylem conducts only in one direction i.e vertically. The xylem parenchyma is responsible for storing the prepared food and assists in the conduction of water. Xylem fibres are supportive in function.Phloem- It consists of four of elements:\xa0sieve tubes, companion cells, phloem fibres\xa0and the\xa0phloem parenchyma. Unlike the xylem, phloem conducts in both directions. It is responsible for transporting food from the leaves to the other parts of the plant. Phloem contains living tissues except for fibres that are dead tissues. They are vascular tissue of plants and help to transport food,water,nutrients etc.in plants |
