Meristematic tissues are classified into three main types based on their location and function: apical meristems, found at the tips of roots and shoots; intercalary or basal meristems, located in the middle regions of stems or leaves, enabling regrowth; and lateral meristems or cambium, responsible for secondary growth in woody plants. At the ...
The quiescent centre is a group of cells, up to 1,000 in number, in the form of a hemisphere, with the flat face toward the root tip of vascular plants. [1] It is a region in the apical meristem of a root where cell division proceeds very slowly or not at all, but the cells are capable of resuming meristematic activity when the tissue surrounding them is damaged.
Vascular tissue is a complex conducting tissue, formed of more than one cell type, found in vascular plants. The primary components of vascular tissue are the xylem and phloem. These two tissues transport fluid and nutrients internally. There are also two meristems associated with vascular tissue: the vascular cambium and the cork cambium.
Meristematic Zone: Right above the root cap and contains the "stem cells" of the plant. In this zone, cells are dividing quickly and there is little to no differentiation present. Root Cap: Protective layer of cells that covers the meristematic tissue. The cells in this part of the root have been seen to play a critical role in gravitropic ...
While plant stem cell exists in the meristematic tissues of plant, callus is obtained as a temporary response to cure wounds in somatic cell. Moreover, callus undergoes dedifferentiation as differentiated cells acquire ability to differentiate; but genetic variation is inevitable in the process because the cells consist of somatic ...
Meristematic tissues that take up a specific role lose the ability to divide. This process of taking up a permanent shape, size and a function is called cellular differentiation. Cells of meristematic tissue differentiate to form different types of permanent tissues. There are 2 types of permanent tissues: simple permanent tissues
The meristem can be defined as the tissue or group of plant tissues that contain undifferentiated stem cells, which are capable of producing any type of cell tissue.Their maintenance and development, both in the vegetative meristem or the meristem of the inflorescence is controlled by genetic cell fate determination mechanisms.
Although it is composed of non-vascular parenchyma cells, it's still considered part of the vascular cylinder because it arises from the procambium as do the vascular tissues it surrounds. [citation needed] In eudicots, it also has the capacity to produce lateral roots. Branch roots arise from this primary meristem tissue.
