Such a vascular bundle is called bicollateral vascular bundle. What are the constituents of phloem? Phloem: It transports prepared food from the leaves to every part of plants. Xylem and phloem are both conducting tissues and also known as vascular tissues; together both them constitute vascular bundles. Also, the chlorenchyma of phloem parenchyma prepares food by process of photosynthesis. Xylem is composed of cells of four different types: 1. Log in. All the cells of xylem except the xylem parenchyma are dead. Xylem and phloem are known as complex tissues as they are made up of more than one type of cells. Phloem has no mechanical function. Phloem conducts organic food. Differentiate between (i) Xylem and phloem (ii) Vessel and sieve tube (iii) Tracheid and vessel Answer: (i) Xylem and phloem – Xylem: Xylem consists of tracheids, vessels, xylem parenchyma and xylem fibres.
