Name the plant tissue having dead cells.

The correct option is A

Xylem

The correct option is A.

Explanation of the correct option:

1. The plant tissue with dead cells is called the xylem.
2. Dead cells make up these tissues since they can give plants mechanical strength and don't need a lot of maintenance.
3. It is a type of plant vascular tissue.
4. Mechanical strength can be helped by xylem fibers.
5. Except for the xylem parenchyma, every part of the xylem is dead.

Explanation of the incorrect options:

Option B:

1. The majority of plant tissues are made up of parenchyma and collenchyma, two cellular structures.
2. Collenchyma cells are alive, in contrast to parenchyma cells.
3. They are made of water and cellulose, which helps the plants maintain their shape.

Option C:

A basic permanent tissue known as parenchyma makes up a large portion of the ground tissues of plants, where vascular tissues and other tissues are attached.

Option D:

Phellogen creates the periderm, a protective tissue that takes the place of the epidermis when the secondary growth displaces and eventually kills the epidermis of the original plant body.

Final Answer: - The plant having dead cells is Xylem.
