Which of the following is not a permanent tissue
A
xylem
B
collenchyma
C
lateral meristem
D
epidermal
Explanation: 

Detailed explanation-1: -Thus the correct answer is Option (A)-Intercalary meristem. Note:-Once the tissue differentiates, it is no more capable of dividing. It forms a permanent tissue.

Detailed explanation-2: -Lateral Meristem It increases the thickness of the plant. Vascular cambium and cork cambium are the two lateral meristems. These divide preclinically or radially and give rise to secondary permanent tissues.

Detailed explanation-3: -Intercalary meristem is present in internodes or stem regions and hence it is not a lateral meristem.

Detailed explanation-4: -There are three primary meristems: the protoderm, which will become the epidermis; the ground meristem, which will form the ground tissues comprising parenchyma, collenchyma, and sclerenchyma cells; and the procambium, which will become the vascular tissues (xylem and phloem).

Detailed explanation-5: -A plant has four kinds of meristems: the apical meristem and three kinds of lateral-vascular cambium, cork cambium, and intercalary meristem.
