Question

Name the components of phloem tissue. Which of these components are dead? Mention its function.

Answer 1

Phloem

Phloem is a type of vascular tissue that conducts the food synthesized to different parts of the body.

Components: The components of phloem tissue are-

• Sieve tubes
• Companion cells
• Phloem parenchyma
• Phloem fibers..

Phloem fibers are the non-living component of phloem as they have lignin thickening in the cell wall which becomes impermeable and thus, the inner protoplasm can not survive.

Function

The main function of phloem is the transport of food synthesized in the green leaves or green parts of the body to the entire body.
