What is True About Plant Meristematic Cells

Question

What is true about plant meristematic cells?
A) They are the main cells involved with transpiration.
B) They produce outgrowths called root hairs.
C) They are undifferentiated cells that produce new cells.
D) They are distributed evenly in all tissues throughout the plant.
E) They subdivided into three distinct cell types named parenchyma, collenchyma, or sclerenchyma.

Accepted Answer

Plant meristematic cells are undifferentiated cells that continuously produce new cells, enabling the plant to grow and develop. They are responsible for primary and secondary growth in plants. Option A is incorrect because transpiration is primarily controlled by specialized cells called stomata. Option B is incorrect because root hairs are extensions of differentiated root epidermal cells, not meristematic cells. Option D is incorrect because meristematic cells are concentrated in specific regions of the plant called meristems. Option E is incorrect because parenchyma, collenchyma, and sclerenchyma are types of mature, differentiated plant cells, not meristematic cells.
