Tissue with dead cells:

Sclerenchyma tissue is the correct answer. Sclerenchyma is a type of plant tissue that provides structural support to the plant. It is composed of cells with thick cell walls made of lignin, a complex polymer that makes the cell walls rigid and impermeable to water. These cells are dead at maturity and have no living contents.

Explanation:

Sclerenchyma tissue:
- Sclerenchyma tissue is a type of permanent tissue found in plants. It is responsible for providing mechanical support and protection to the plant.
- The cells of sclerenchyma tissue are characterized by thick, lignified cell walls.
- These thick cell walls contain a high amount of lignin, a complex polymer that makes the cell walls rigid and impermeable to water.
- The presence of lignin in the cell walls gives sclerenchyma tissue its characteristic hardness and strength.
- Unlike other plant tissues, the cells of sclerenchyma tissue are dead at maturity and have no living contents. This is because the thickened cell walls occupy most of the cell's volume, leaving little room for other cellular components.
- The dead cells of sclerenchyma tissue provide strong structural support to the plant, allowing it to withstand mechanical stresses and maintain its shape.

Other tissue types:
- Parenchyma tissue: Parenchyma tissue consists of living cells with thin cell walls. It is found in various parts of the plant, such as leaves, stems, and roots. Parenchyma cells play a role in photosynthesis, storage, and secretion.
- Collenchyma tissue: Collenchyma tissue consists of living cells with unevenly thickened cell walls. It provides mechanical support to young parts of the plant, such as growing stems and petioles.
- Epithelial tissue: Epithelial tissue is found in animals and covers the surfaces of organs, lines body cavities, and forms glands. It is composed of tightly packed cells that protect underlying tissues, absorb nutrients, and secrete substances.

In summary, the tissue with dead cells is sclerenchyma tissue. It is characterized by thick, lignified cell walls and provides strong structural support to the plant. Parenchyma, collenchyma, and epithelial tissues, on the other hand, consist of living cells.
