Question 3
In the longitudinal section of a root tip, region A — A′ lies just above the root cap. What is found there?
The right answer is the one marked above.
Cells that are dividing constantly, all much alike. That is the meristematic region, and it is why the growing tip of a root is soft and pale.
Region B — B′, further up, is where several kinds of cell appear, noticeably different in form. That is permanent tissue.
