WebbThe studied species of Opuntia have different size of collateral vascular bundles ordered in eustele. The small ones are formed by phloem, and opposite to the phloem on the inner side is the xylem, with two to ten narrow vessels, with helical secondary walls, and disposed in a row, intercalate with parenchyma of the xylem. WebbThe cell cannot function without certain organelles and must rely on the organelles of the companion cells. The companion cell is responsible for all metabolic functions of the sieve tube member. The companion cell is essential for the survival of the sieve tube member. This will cause the member to cease phloem function and kill the plant.

Webbthe entry of water and mineral salts into xylem vessels. • Pericyc1e forms a layer next to the endodermis. • Next to the pericycle is the vascular tissue. • In the Dicotyledonous root, xylem forms a star shape in the centre, with phloem in between the arms. • It has no pith.
WebbThe phloem transports amino acids and sugars in both directions: up and down the plant. The transpiration stream refers to the process of water evaporation from the leaves. The rate of transpiration is affected by: light, temperature, humidity & wind.
