On the basis of location, meristems are of three types, apical, intercalary and lateral.

On the basis of location, meristems are of three types, apical, intercalary and lateral.(i) Apical: It is present at the apices of stem, root and their branches.

On the basis of location, meristems are of three types, apical, intercalary and lateral.(i) Apical: It is present at the apices of stem, root and their branches.Functions: It helps in growth in length and formation of primary tissues.

On the basis of location, meristems are of three types, apical, intercalary and lateral.(i) Apical: It is present at the apices of stem, root and their branches.Functions: It helps in growth in length and formation of primary tissues.(ii) Intercalary: It is found above or below stem nodes and leaf bases.

Function: Formation of protective cork (phellem) and aerating lenticles on the outside and secondary cortex (phelloderm) on the inner side.

Function: Formation of protective cork (phellem) and aerating lenticles on the outside and secondary cortex (phelloderm) on the inner side. (b) Vascular Cambium: In stem it is formed from intra-fascicular cambial strips and interfascicular strips. In root it develops from conjuctive parenchyma and pericycle. Function: Formation of secondary phloem on the outer side and secondary xylem on the inner side. Vascular rays are formed at intervals for radial conduction.

Answer 2

We know that there are three types of meritism. The three types of Meritism are given as –

• Lateral Meritism – This Meritism is located at side of mature tissues of roots and shoot. The function of this meritism is to increase the circumference of plant.

• Apical Meritism – This Meritism is located at the tips of roots & shoots. The function of Meritism is to enlarge length of the plants.

• Intercalary Meritism – This Meritism is located between the matured tissues ( group of cells ). The function of Meritism is to regenerate the grass afterwards it's taken inside the stomach of any animal (cattle) such as : Cow, Goat, Etc,..
