Question

Name the conducting tissue in plants that is made up of dead cells?
`

Answer 1

Hint: A group of more than one type of cells having a common origin and working together as units called complex permanent tissues. The important complex tissue is vascular plant as xylem and phloem. The xylem and phloem tissue both are conducting tissue.

Complete answer: XYLEM: Xylem is the chief conducting tissue of vascular plants responsible for the conduction of water and inorganic solutes. Xylem is a complex permanent tissue that consists of tracheids, vessels, xylem parenchyma, and xylem fibers.
Tracheids, vessels, and xylem fibers are dead cells whereas xylem parenchyma is living.
PHLOEM: Phloem is a complex permanent tissue which consists of sieve-tube members, companion cells, phloem parenchyma, and phloem fibers.
Sieve tube members, companion cells, and phloem parenchyma are living whereas phloem fibres are dead. Mature sieve tubes are without nuclei.
Xylem tissue is mainly composed of dead cells

Additional information: XYLEM :
1. Xylem is mainly concerned with the conduction of water or sap
2. Xylem also provides mechanical support to the plant
3. The treachery elements (i.e. tracheids and vessels) have different types of wall thickenings due to the deposition of lignin.
4. Xylem is generally located towards the inner side of the plant parts.
5. It constitutes the bulk of woody parts.
PHLOEM :
1. Phloem is mainly concerned with the conduction of organic solutes.
2. The main conducting elements ( i.e. sieve tubes) have no wall thickenings.
3. Lignin is absent in phloem.
4. It is generally located towards the outer side of the plant parts.
5. It constitutes a small part of the vascular tissue.

So the correct answer is Xylem

Note: Xylem primarily consists of dead cells while phloem is composed of living cells.
