Which simple tissue has non-living cells: parenchyma, collenchyma, or sclerenchyma?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Sclerenchyma is the simple tissue that consists of non-living cells at maturity. While parenchyma and collenchyma tissues contain living cells with active cytoplasm, sclerenchyma cells die after they develop thick, lignified cell walls. This death is functional—the rigid, empty cell walls provide maximum mechanical support and protection without requiring metabolic maintenance. The lignified walls make sclerenchyma extremely durable, which is why this tissue is used in making ropes, mats, and provides hardness to structures like nutshells.
