Explain the types of meristematic tissues with a neat labelled diagram.Pls answer soon and correctly
Answers
Answer:
Meristematic tissues, or simply meristems, are tissues in which the cells remain forever young and divide actively throughout the life of the plant.
A plant has three kinds of meristematic tissue.
Apical Meristem
These are present at the tips of the roots and shoots and helps in the increase of the height of the plants.
Various cell divisions facilitate the growth of the cells in the roots and shoots and help in cellular enlargement.
Apical meristem is divided into-promeristem zone, which contains actively dividing cells, and the meristematic zone, which contains protoderm, procambium, and ground meristem.
Intercalary Meristem
It is located in the leaves and internodes at the intercalary position.
These help to increase the length of the internode.
It is found in grass, monocots, and pines.
It is a part of apical meristem and adds to the height of the plant.
Lateral Meristem
It is located in the stems and roots on the lateral side.
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.
Answer:
Meristematic tissues, or simply meristems, are tissues in which the cells remain forever young and divide actively throughout the life of the plant. ... A plant has four kinds of meristems: the apical meristem and three kinds of lateral—vascular cambium, cork cambium, and intercalary meristem.
