Question

What type of meristematic tissue allows them to regrow after being cut down?

1) Apical meristem
2) Intercalary meristem
3) Lateral meristem
4) All of the above

Answer 1

Lateral meristems are primarily responsible for the regrowth of plants in terms of girth after being cut down, though apical and intercalary meristems also play roles in elongation and leaf blade elongation.

Step-by-step explanation:

Lateral meristems, which include the vascular cambium and cork cambium, are responsible for growth in thickness or girth in a maturing plant. Apical meristems, at the tips of stems and roots, enable a plant to extend in length while intercalary meristems, found only in monocots at the bases of leaf blades and nodes, allow leaf blades to elongate. In this case, all of the above meristems contribute to the regrowth of a plant in different ways, with lateral meristems particularly involved in regenerating girth after a plant has been cut down.
