What is meristem cells?
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.
How do meristem cells work?
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.
Where are meristems found?
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 are the types of meristem?
Based on the positions, meristems are of three types – lateral meristem, intercalary meristem and apical meristem. Lateral meristems – seen in the stems and roots on the lateral side. They increase the thickness of the plant. The two lateral meristems are cork cambium and vascular cambium.
What is meristem write the types of meristem?
There are three types of meristem which are differentiated based on position of the meristem are apical meristem, intercalary meristem and lateral meristem. These meristems perform different activities based on their location. Apical meristem is located at the tip of roots, stem and branches.
What is the unique feature of meristem?
Meristematic tissue consist of actively dividing cells this is found in regions such as the tips of stems or roots and lead to increase in length and thickness of the plant this cells are spherical oval polygonal and rectangular and have thin cells walls.
Does meristematic cells differentiate?
As cells leave the meristem, they undergo differentiation to form specific cell types.
Are meristem cells stem cells?
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 is meristematic tissue write its characteristics?
The meristematic tissue is living and thin-walled. The protoplasm of the cells is very dense. The meristematic tissues heal the wounds of an injured plant. The cells of the meristematic tissue are young and immature.
What is the location of meristematic tissue?
The apical meristem, also known as the “growing tip,” is an undifferentiated meristematic tissue found in the buds and growing tips of roots in plants. Its main function is to trigger the growth of new cells in young seedlings at the tips of roots and shoots and forming buds.
