AApical meristem
BLateral meristem
CIntercalary meristem
DVascular cambium
Answer & Solution
Correct answer: C. Intercalary meristem
1. Meristematic tissues are named by location, and one of the three is restricted to monocots.
2. Intercalary meristems sit at the bases of leaf blades and at nodes, and they occur only in monocots.
3. This tissue lets a monocot leaf blade lengthen from its base, which is why lawn grass regrows after mowing.
4. Apical meristems sit at stem and root tips in all vascular plants, so they are not monocot specific.
5. Lateral meristems and the vascular cambium add girth in woody plants rather than length at a leaf base.
