Detailed explanation-1: -Final answer: Sclerenchyma tissues have dead cells.
Detailed explanation-2: -Mature sclerenchyma cells are usually dead cells that have heavily thickened secondary walls containing lignin. The cells are rigid and nonstretchable and are usually found in nongrowing regions of plant bodies, such as the bark or mature stems.
Detailed explanation-3: -Sclerenchyma cells has dead cell, it consists of heavily thickened walls which contains lignin, it makes impermeable to wall and cells can’t survive.
Detailed explanation-4: -Collenchyma is living tissue. Similar cells make up their structure. A strong primary cell wall consisting of cellulose and pectin makes up the only component of collenchyma cells, which are often alive cells.
Detailed explanation-5: -So, the correct answer is ‘Sclerenchyma’.
