Structure of phloem drawing
WebIt is a critical structure for phloem function. The parenchyma consists of unspecialised cells used for storage and two specialised cells namely – companion cells and albuminous cells. The companion cells, as the name suggests are the companion of the sieve tube cells that help in carrying out the metabolic functioning of the sieve elements. WebStructural support Food storage Xylem tissue is made up of four cell types that function together: Tracheids (long, narrow tapered cells with pits) Vessel elements (large with thickened cell walls and no end plates when mature) Xylem parenchyma Sclerenchyma cells (fibres and sclereids)

WebPhloem is a complex tissue made up of various cell types; its bulk is made up of sieve tube elements which are the main conducting cells and companion cells. Other cell types of phloem tissue also include parenchyma for storage and strengthening fibres. Mature phloem tissue contains living cells, unlike xylem tissue. Structure of phloem tissue. WebThe region of ground tissue that is between the vascular cylinder and the epidermis is called the cortex. Similar to the monocots, the primary xylem is located in the region of the vascular tissue facing the center of the stem, while the primary phloem is produced toward the exterior of the stem.

WebPhloem mostly contains sugar molecules dissolved in water forming a very thick sugary sap, which is food for them. And if you're wondering what these things are over here at the sides, that is some leftover cytoplasm. The cells don't lose all of their cytoplasm. And similarly, this is the cell walls.
