Question

Differentiate between Xylem and phloem

Answer 1

1. Xylem and Phloem are two different types of vascular tissues, which are mainly involved in the transportation process.
2. These tissues form a vascular bundle and these work together as a unit. The movement of xylem is unidirectional, while the movement of phloem is bidirectional.

Meaning	Complex tissue of plants that transports water and nutrients within the plant.	Living tissue that transports food and organic materials within the plant.
Type of Cell	2. Contains dead cells with the exception of parenchyma.	2. Contains of mostly living cells.
Materials	3. It comprises of fibre, tracheids, and xylem vessels.	3. It comprises of sieve cells, sieve tubes, phloem fibres, phloem parenchyma, and companion cells.
Location	4. The location of xylem is deep in the plant, in the centre of vascular bundle.	4. The location of phloem is on the outer side of the plant’s vascular bundle.
Mechanical Support	5. It provides mechanical support.	5. Provides no mechanical support.
Type of Movement	6. Undirectional.	6. Bidirectional.
Proportion of Plant	7. Xylem constitutes mostly the bulk of the body of the plant.	7. Phloem constitutes a small part of the body of the plant.
Conducting Cells	8. In xylem, the conducting cells are dead.	8. In phloem, the conducting cells are certainly living.
