Read the following statements regarding meristematic cells and select the CORRECT ones (i) Root apical meristem occupies the tip of the root while the shoot apical meristem occupies the distant most region of the stem axis. (ii) The meristem which occurs between mature tissues is known as intercalary meristem. (iii) Both apical meristems and intercalary meristems are secondary meristems.

Options

  1. A(i) and (ii)
  2. B(ii) and (iii)
  3. C(i) and (iii)
  4. D(i), (ii) and (iii)

Correct answer

A. (i) and (ii)

Step-by-step solution

The meristems which occur at the tips of roots and shoots and produce primary tissues are called apical meristems. Root apical meristem occupies the tip of a root while the shoot apical meristem occupies the distant most region of the stem axis. During the formation of leaves and elongation of stem, some cells ‘left behind’ from shoot apical meristem, constitute the axillary bud. Such buds are present in the axils of leaves and are capable of forming a branch or a flower. The meristem which occurs between mature ti
