Question

............ gives flexibility to the plants.

• A. Collenchyma
• B. Parenchyma
• C. Aerenchyma
• D. Sclerenchyma

Answer 1

The correct option is A Collenchyma

• Parenchyma cells are thin-walled, flexible and loosely packed cells. They are often alive at maturity. Their shape changes as per function. They are filler tissue in soft parts of the plant. In leaves, parenchyma cells carry out photosynthesis. They are also involved in wound repair.
• In many aquatic plants, parenchyma cells have large air cavities to give buoyancy to the plant and enable them to float in water. Such parenchyma cells are called as aerenchyma.
• Sclerenchyma cells are dead, long, thin and narrow with thickened walls without any intercellular space. This tissue makes the plant hard and stiff.
• Collenchyma cells are living, elongated and irregularly thickened at corners with less intercellular space. It allows easy bending of plant parts without breaking.

So, the correct answer is option A.
