What is meristematic cell division?
What is meristematic cell division?
Meristematic cells are undifferentiated or incompletely differentiated. They are totipotent and capable of continued cell division. Division of meristematic cells provides new cells for expansion and differentiation of tissues and the initiation of new organs, providing the basic structure of the plant body.
What is meristematic tissue explain with diagram?
Meristematic tissue consists of cells that are capable of division and possesses totipotency—that is, capability to give rise to all cell types of the body. Its cells divide and help in increasing the length and girth of the plant. The meristematic cells are compactly arranged and have thin cellulosic cell walls.
Does meristem cell undergo cell division?
Some of these cells, known as initials, maintain the meristem as a continuing source of new cells and may undergo mitosis (cell division) many times before differentiating into the specific cells required for that region of the plant body.
What is the function of meristematic cell?
Meristematic tissue consists of undifferentiated cells, which are active and capable of dividing throughout their life. The continued cell division initiates new cells for expansion, differentiation of tissues and new organs.
What is the difference between meristematic and stem cells?
While meristem cells share a number of characteristics with stem cells of animals, one of the main differences between the two lies in the fact that meristem cells can be restored and continue dividing which in turn allows indeterminate growth in plants (as long as the necessary resourses are available).
What is meristematic tissue class 11?
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.
What is the other name of meristematic tissue?
Supplement. A meristem is comprised of indeterminate, actively dividing cells that give rise to differentiated tissues such as epidermis, trichomes, phellem, and vascular tissues. The meristem (also called meristematic tissue) is responsible for the growth of plants.
Does mitosis happen in meristems?
1 Answer. In plants, mitosis only occurs in the meristematic tissue.
Does mitosis occur in the meristem?
Mitosis occurs in terminal zones of cells called the meristem, of which there are two types—apical meristems, discussed here, and lateral meristems which will be discussed briefly in 7 Sect.
What are the characteristics of meristematic cells?
The cells are isodiametric with thin cellulosic cell walls with no secondary cell wall.
Where is meristem located?
Meristems are regions of unspecialised cells in plants that are capable of cell division. Meristems make unspecialised cells that have the potential to become any type of specialised cell. They are only found is certain parts of the plant such as the tip of roots and shoots and in between the xylem and phloem.
Where are meristematic cells found?
Meristem cells are a group of cells that reside at the shoot and root tips of plants. As undifferentiated (or slightly differentiated cells) they are considered as stem cells given that they are the origin of many of the cells that go on to rapidly differentiate/specialize and form various parts of the plant.
What are the main features of meristematic tissue?
Features of meristematic tissues:
- (i) Cells divide repeatedly.
- (ii) Cell walls are thin.
- (iii) Vacuoles are not found.
- (iv) Metabolically very active.
- (v) They have dense cytoplasm.
- (vi) They have prominent nucleus.
What are the features of meristematic cells?
Characteristics of Meristematic Tissue Every time the cell divides, one cell remains identical to the parent cell, and the others form specialized structures. They have very small and few vacuoles. The meristematic tissue is living and thin-walled. The protoplasm of the cells is very dense.
Where are meristem cells located?
Meristems make unspecialised cells that have the potential to become any type of specialised cell. They are only found is certain parts of the plant such as the tip of roots and shoots and in between the xylem and phloem.
What is meristematic tissue function?
Where is meristematic tissue located?
Meristematic tissues are found in many locations, including near the tips of roots and stems (apical meristems), in the buds and nodes of stems, in the cambium between the xylem and phloem in dicotyledonous trees and shrubs, under the epidermis of dicotyledonous trees and shrubs (cork cambium), and in the pericycle of …
What is function of meristematic tissue?
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. The cells actively divide to produce new cells.
Which kind of cell division takes place in the apical meristem?
The type of cell division that occurs in apical meristem of plants is Mitosis.
