Question

Compare the statements a and b
Statement a : Sclerenchyma cells do not have plasmodesmata.
Statement b : Cell walls of some permanent tissues are heavily lignified.

• A. Statement a is correct and b is wrong
• B. Both the statements a and b are wrong
• C. Both the statements a and b are correct
• D. Statement a is wrong and b is correct

Answer 1

The correct option is C Both the statements a and b are correct

Plasmodesmata are narrow channels that act as intercellular cytoplasmic bridges to facilitate communication and transport of materials between plant cells and are not found in Sclerenchyma cells. Sclerenchyma fibres are long and narrow and have thick lignified cell walls. They provide mechanical strength to the plant and allow for the conduction of water. Sclereids are specialised sclerenchyma cells with thickened, highly lignified walls with pits running through the walls.

So, the correct option is C.
