Which of the Following Cell Types is Least Likely to Be

Question

Which of the following cell types is least likely to be capable of cell division?
A) mesophyll cell in a developing leaf
B) parenchyma cell 2 mm from the tip of a root
C) parenchyma cell in a dormant axillary bud
D) functional tracheid cell in a stem

Accepted Answer

Functional tracheid cells in a stem are typically fully differentiated and specialized for their function of water transport, which typically means they have lost the ability to undergo cell division. In contrast, both mesophyll cells in developing leaves and parenchyma cells near root tips are likely to retain the ability to undergo cell division when appropriate signals are present. Parenchyma cells in dormant axillary buds may also be capable of cell division if they become activated and start growing.
