If a student wants to observe cells that are actively dividing to increase the length of a plant stem or root, which specific tissue should they examine under the microscope?
Apical meristem
The apical meristem is present at the tips of roots and shoots, where its cells actively and continuously divide by mitosis to bring about an increase in the length of the stem or root (primary growth).
Lateral meristem increases girth, permanent tissue does not divide, and intercalary meristem occurs at the base of internodes.
Hence, the correct answer is Apical meristem (B).
