Meristems are tissues that contains undifferentiated or meristematic cells. These are found in the plant part like stem and root tip where growth takes place
for class 10-Meristematic tissues contain living cells with varied shapes. They possess a large nucleus devoid of the vacuole. The cells have no intercellular space. The zone where these cells exist is known as meristem.
for class 9-Meristematic tissues are the cells or groups of cells that have the ability to divide. These cells divide continuously and thus helps in increasing the length and thickness of the plant.
for class 8-
Tissues made up of actively dividing cells are called meristematic tissues or meristems. Meristematic tissues are responsible for plant growth. They are present at the tips of roots,stem and branches. The cells present in these tissues constantly divide to produce new cells.
for class 7- Meristematic tissues are the plant tissues which are made up of actively dividing cells. These tissues actively divide and lead to the growth of the plant body. They are found at the growth points of the plant like tips of root, stem and branches etc.06-May-2020
Explanation:
DEFINITION
Characteristics of meristematic tissue
The Meristem is plant tissue capable of cell divison forming new tissues. It actively divides cells adding new cells to plant. Meristem contains undifferentiated cells procuding specialized cells structures. Apical meristem, intercalary meristem and lateral meristem are categories of Meristematic Tissue.
The characteristics of meristematic tissue are as follows:
1. Cells are small and usually cubical.
2. Cell walls are thin and Nuclei are large.
3. Vacuoles are almost absent.
4. Cells tightly packed with almost intercellular spaces.
5. The new cell produced is transformed into mature permanent tissues.
6. Meristematic tissues are classified on the basis of origin, position, and function.
DEFINITION
Types of meristematic tissue
