Question

A secondary meristematic tissue can develop due to the resumption of power of division in

• A. parenchyma and sclerenchyma
• B. parenchyma and collenchyma
• C. collenchyma and sclerenchyma
• D. parenchyma, collenchyma and sclerenchyma

Answer 1

The correct option is B parenchyma and collenchyma

Simple permanent tissues such as parenchyma and collenchyma can gain the ability to divide by undergoing a phenomenon called dedifferentiation and become meristematic once again. This is possible because both parenchyma and collenchyma are simple, homogenous and living (nucleated).
Sclerenchyma is a simple dead mechanical tissue. So, it cannot become meristematic again.
