Answer will be D

Answer

Cork cells are dead cells that make up the outer bark of a tree. They are responsible for providing protection and insulation to the tree. Cork cells have several unique characteristics that set them apart from other types of plant cells.

Structure and Function of Cork Cells:

Cork cells are derived from the cork cambium, which is a type of meristematic tissue found in the outermost layer of a plant stem. As the cork cambium divides, it produces new cells that are gradually pushed towards the outer surface of the stem. These cells undergo a series of changes, including loss of their protoplasts (cell contents) and deposition of a substance known as suberin in their cell walls. This process is called corkification.

Once cork cells have completed the process of corkification, they become dead and fully mature cells. The suberin in their cell walls makes them impermeable to water and gases, allowing them to provide an effective barrier against pathogens, mechanical injuries, and water loss.

Importance of Cork Cells:

Cork cells play a crucial role in the survival and growth of woody plants. Some of their key functions include:

1. Protection: The thick layer of cork cells acts as a protective barrier, shielding the underlying tissues from physical damage, pathogens, and extreme temperatures.

2. Insulation: The dead cells and the air-filled spaces between them provide insulation, helping to regulate the temperature inside the plant and prevent heat loss.

3. Waterproofing: The impermeable nature of cork cells prevents water loss through the outer surface of the stem, reducing the risk of dehydration.

4. Buoyancy: The air-filled spaces in cork cells also contribute to the buoyancy of certain tree species, enabling them to float in water.

Conclusion:

In conclusion, cork cells are dead cells that make up the outer bark of a tree. They are structurally modified to provide protection, insulation, and waterproofing to woody plants. Although they are dead, their unique characteristics and functions make them essential for the survival and growth of trees.
