Detailed explanation-1: -The apical meristem is a group of cells that retain the ability to continue divisions, forming new cells continuously as the plant grows. This PRIMARY growth is responsible for growth in height.
Detailed explanation-2: -All plants exhibit at least one form of apical meristem consisting of one or more cells that are functionally analogous to metazoan stem cells because they are histogenetic, i.e., able to generate specialized tissues.
Detailed explanation-3: -A plant has four kinds of meristems: the apical meristem and three kinds of lateral-vascular cambium, cork cambium, and intercalary meristem.
Detailed explanation-4: -The shoot apical meristem produces the three primary meristems: procambium, ground meristem, and protoderm.
