Question

What are the constituents of Phloem and Xylem​

Answer 1

1: Tracheids and vessel elements: Tracheids (top) and vessel elements (bottom) are the water conducting cells of xylem tissue. Phloem tissue is responsible for translocation, which is the transport of soluble organic substances, for example, sugar

Answer 2

1)The structural elements of xylem are tracheids, vessels or tracheae, xylem fibres, xylem parenchyma and rays. The tracheid is derived from a single cell and can be regarded as the basic cell type of xylem tissue. 2)Phloem tissue consists of conducting cells, generally called sieve elements, parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells and supportive cells, such as fibres and sclereids.
