Show Answer

Answer:

Correct Answer: B

Solution:

Even, if there is more than one tunica layer in the stem apex, only the outer layer will develop into the epidermal cells. The stem has three simple cell types, i.e. the parenchyma, collenchyma and sclerenchyma cells which are responsible for the metabolic functions, repairing and healing wounds and storing starch.

The correct option is B.
