In the following question, a Statement of Assertion (A) is given follo...
Statement: Collenchyma is dead cell.
Reason: Walls of collenchyma cells are completely thickened.
Solution:
The given statement and reason are both incorrect. Here's the explanation:
Collenchyma Cells:
1. Collenchyma cells are living cells found in the plants.
2. They provide mechanical support to the growing parts of the plant, such as stems and petioles.
3. These cells have irregularly thickened primary cell walls, which can be localized at the corners or throughout the cell wall.
4. The thickening of the cell walls in collenchyma cells is due to the deposition of cellulose, hemicellulose, and pectin.
5. Collenchyma cells also have living protoplasts, which occupy the central region of the cell.
Explanation:
1. The assertion that collenchyma is a dead cell is incorrect because collenchyma cells are actually living cells.
2. The reason provided is also incorrect because although the walls of collenchyma cells are thickened, they are not completely thickened.
3. The thickening of cell walls in collenchyma cells provides strength and flexibility to the plant, allowing it to withstand mechanical stress.
4. Collenchyma cells play a crucial role in supporting young and growing plant parts.
Conclusion:
Therefore, neither the assertion nor the reason is true. The correct answer is option D: Both Assertion and Reason are false.
Reason: Walls of collenchyma cells are completely thickened.
