Question

Which among the following statements are correct with respect to simple permanent tissues?

• A. Chlorenchyma is involved in photosynthesis.
• B. Collenchyma allows bending of tendrils without breaking.
• C. Sclerenchyma is a hard, non lignified and dead tissue.
• D. Parenchyma is the most common simple permanent tissue.

Answer 1

Answer: (A), (B), (D)

The correct options are
A Chlorenchyma is involved in photosynthesis.
B Collenchyma allows bending of tendrils without breaking.
D Parenchyma is the most common simple permanent tissue.

• Parenchyma which contains chloroplasts is called chlorenchyma. It is involved in the process of photosynthesis.
• Collenchyma allows bending of various plant parts like tendrils and stems of climbers without breaking.
• Sclerenchymatous cells are generally dead. As the cell matures, high levels of lignin gets deposited in their walls making it impermeable to water, thus making the cell dead.
• Parenchyma is a simple permanent living tissue. It is made up of thin walled similar isodiameric cells. It is the most abundant and common tissue of plants.
