Question

Which tissue provides flexibility to plants?

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

Answer 1

Answer: (B)

Collenchyma

A. Parenchyma is the most common and abundant tissue in plants which is made up of thin walled living cells having a distinct nucleus. This tissue stores food material.

B. Collenchyma is a specialised simple permanent tissue that provides support and flexibility to plants. This tissue is made up of living cells having uneven thickenings of cellulose, pectin and hemicellulose on the walls.

C. Sclerenchyma is a lignified supportive tissue made up of thick walled and lignified cells. This tissue provides mechanical support to the plants.

D. Aerenchyma is a type of parenchyma tissue present in aquatic plants. The cells have air spaces or cavities and this provides buoyancy to plants and hence, help them to float.

So, the correct answer is 'Collenchyma'.
