Dead Cells in Sclerenchyma Tissue
Sclerenchyma tissue is the type of plant tissue that contains dead cells. This tissue provides support and protection to the plant.
Characteristics of Sclerenchyma Tissue:
- Sclerenchyma cells have thick, lignified cell walls that provide strength and rigidity to the plant.
- These cells lack protoplasts (living contents) at maturity, making them dead cells.
- Sclerenchyma cells are long and narrow, with tapered ends.
Function of Sclerenchyma Tissue:
- The primary function of sclerenchyma tissue is to provide mechanical support to the plant.
- These cells also provide protection to the plant by forming a hard outer covering in certain plant parts.
Examples of Sclerenchyma Tissue:
- Sclerenchyma cells can be found in the seed coats, shells of nuts, and the hard outer covering of stems and roots.
In contrast, parenchyma and collenchyma tissues contain living cells that are involved in various physiological functions such as photosynthesis, storage, and support. Epithelial tissues are found in animals and also consist of living cells. Therefore, the correct answer is that sclerenchyma tissue contains dead cells.
