Question

Find out the correct sentences.

• A. Parenchymatous tissue have intercellular spaces.
• B. Collenchymatous tissue are irregularly thickened at corners.
• C. Apical and intercalary meristems are permanent tissues.
• D. Both A and B

Answer 1

The correct option is D Both A and B

Meristematic tissue contains cells, which are undifferentiated and can divide and form new cells.
Permanent tissues contain cells, which are differentiated and cannot divide to give rise to new cells. Hence, apical and intercalary meristems are not a permanent type of tissues. Therefore, option C is incorrect.
Meristematic cells perform the role of giving rise to new cells. For this purpose, they have dense cytoplasm and thin cell wall. Vacuoles possess cell sap and provide rigidity and turgidity to the cell. This might pose a problem for cell division. Due to this reason meristematic cells lack vacuole. Therefore, option D is incorrect.
Parenchyma cells are live cells with thin cells walls. These cells are loosely packed. Therefore, they have intercellular spaces. Hence, option A is correct.

Collenchymatous cells are elongated cells with irregularly thickening at corners. They have less intercellular spaces. Therefore, option B is correct.

So, the correct answer is option D.
