Intercalary Meristem:- They are present at the base of the leaves or internodes of the twigs. They are actively growing meristems that differ clearly from apical meristems and are located between more or less differentiated tissues usually at the base of each internode. The term meristem was coined by Nageli (1858). Differentiate between self & cross pollination. The apical meristem is the growth region in plants found within the root tips and the tips of the new shoots and leaves. Meristematic tissue cells are either undifferentiated or incompletely differentiated, and they continue to divide and contribute to the growth of the plant. Meristematic tissues consist of three types, based on their location in the plant. What are the function of Ligaments and Tendons? The product of two natural numbers is 9222.

Apical meristems contain meristematic tissue located at the tips of stems and roots, which enable a plant to extend in length. Function-This tissue helps in increase of the length of organs like leaves and internodes. b) Veins have valves in them. In desert plants it may be even more thick and waxy. Lateral meristems facilitate growth in thickness or girth in a maturing plant. The meristematic tissue is usually found in the apices of the root systems and the shoots and is in a continuous state of division. Basal meristematic tissue is within mature plant tissue and allows growth at the base (like grass still growing after the top is cut off) and the lateral growth in plants (growth in di.
