(o) primary meristem
(c) Intercalary meristem(d) Apical meristem​

Answer 1

c.lntercalary meristem

Explanation:

the elongation in grasses occurs due to that the lntercalary meristem .

Answer 2

Answer: The correct answer is intercalary meristem.

Explanation: The intercalary meristem is the part involved in elongation because meristematic tissue is considered totipotent as every cell of meristematic tissue have the ability to grow and differentiate into a new cell and they are divided in lateral which helps in the development of girth because these meristems differentiate in a horizontal direction towards the periphery then there is apical meristem which grows in the apex region to form the shoot and primary meristem is the one which helps in the growth of primary structures of the plant and intercalary meristem grows in or differentiates in the longitudinal or vertical direction so helps in elongation and also the stem of grasses and related plants elongate by the activity of intercalary meristem. In angiosperms, intercalary meristems occur only in monocot stems at the base of nodes and leaf blades. Horsetails also exhibit intercalary growth. Intercalary meristems are capable of cell division, and they allow for rapid growth and regrowth of many monocots. Intercalary meristems at the nodes of bamboo allow for rapid stem elongation, while those at the base of most grass leaf blades allow damaged leaves to rapidly regrow. This leaf regrowth in grasses evolved in response to damage by grazing herbivores but is more familiar to us in response to lawnmowers.
