Question

Name the plant tissue which have dead cells? How did they become non-functional? Where is such a type of tissue in plants?​

Answer 1

Answer:

Sclerenchyma cells are dead cells at maturity and have a very thick cell wall due to the deposition of lignin.

They are either present in the form of fibres or sclereids (stone cells).

They are located in the leaf veins, hard coverings of the seeds and vascular bundle.

Its main function include- 1) provide rigidity and mechanical support to the plant body, 2) It also makes the plant stiff and hard.

So, the correct answer is 'Sclerenchyma'.

Answer 2

Answer:

schlerenchyma. They are known to have extremely thick cell walls and do not participate in many of the other activities of the developing plant, such as photosynthesis, because their focus is strictly on support and structure.

They are found mainly in the cortex of stems and in leaves.
