What is differentiation dedifferentiation?
Dedifferentiation is the regaining of the capacity to divide by differentiated cells in a particular part of the plant body. It allows a part of the plant to produce new cells. Therefore, differentiated cells generally undergo dedifferentiation preliminary to major physiological or structural change.
What is cellular differentiation in plant tissue culture?
➢The process of the growth accompanied by. morpho-physiological specialization of the cells produced by the meristems is called differentiation. ➢In plant tissue culture, differentiation is used to. describe the formation of different cell types and. organs in the callus or cell culture.
What is differentiation dedifferentiation and redifferentiation in plants?
The major distinction between dedifferentiation and redifferentiation is that dedifferentiation is the process of differentiated cells in plants regaining the ability to divide mitotically, whereas redifferentiation is the process of dedifferentiated cells losing the ability to divide.
What is plant tissue culture simple definition?
Plant tissue culture is defined as culturing plant seeds, organs, explants, tissues, cells, or protoplasts on a chemically defined synthetic nutrient media under sterile and controlled conditions of light, temperature, and humidity.
What is dedifferentiation and redifferentiation in tissue culture?
In dedifferentiation process, the cells that have lost the capability to divide, regains its dividing property under certain conditions. On the other hand, redifferentiation process is where the cells divide and produce cells which once again lose their dividing capacity but matures to perform specific functions.
What is the phenomenon of differentiation?
The living differentiated cells that have lost the capability to divide can regain the capacity of the division under certain conditions; this phenomenon is called dedifferentiation.
What is differentiation and growth?
In a developing organism, differentiation implies increasing structural and functional complexity. One kind of differentiation concerns changes in gross shape and organization. Such activities, related to molding the body and its integral parts into form and pattern, comprise the processes called morphogenesis.
What is redifferentiation in biology?
Redifferentiation is the process of maturing of dedifferentiated cells to perform specific functions and lose their capacity to divide again. E.g. Formation of secondary phloem, secondary xylem, secondary cortex, cork, etc. from interfascicular cambium and cork cambium.
What are the different types of tissue culture?
Types of Tissue Culture
- Seed Culture. In this culture, the explants are obtained from an in-vitro derived plant and introduced into a laboratory where they proliferate.
- Embryo Culture.
- Callus Culture.
- Organ Culture.
- Protoplast Culture.
- Other Types.
- Initiation Phase.
- Multiplication Phase.
Which one is an example of redifferentiation?
Where does differentiation occur in plants?
meristems
Cell division in plants occurs in regions called meristems . Cells of the meristem can differentiate to produce all types of plant cells at any time during the life of the plant. The main meristems are close to the tip of the shoot, and the tip of the root.
What is differentiation in biology tissues?
Differentiation in (developmental biology) refers to the normal process by which a less specialized cell undergoes maturation to become more distinct in form and function. It is also called cell differentiation.
What is the purpose of cell differentiation?
Cell differentiation is an important process whereby a single cell gradually develops various tissues and organs. It helps in the development of an organism from a single cell zygote.
Which is an example of dedifferentiation?
What are the basic principles of tissue culture?
Tissue culture is in vitro maintenance and propagation of isolated cells tissues or organs in an appropriate artificial environment. Many animal cells can be induced to grow outside of their organ or tissue of origin under defined conditions when supplemented with a medium containing nutrients and growth factors.
What is tissue culture in biotechnology?
However, in general, the tissue culture includes the term tissue culture as well as cell culture, organ culture and suspension culture also. Plant tissue culture is fundamental to most aspects of biotechnology of plants. It is evident now that plant biotechnology is one of the most beneficial of all the sciences.

How did the methods of plant tissue culture develop?
With the identification of a variety of chemicals like cytokinin, auxin, other hormones, vitamins, etc. and their role in affecting cell division and differentiation, the methods of plant tissue culture developed in a proper manner.
Why is cell differentiation important in plants?
The differentiation of the cells is an important event of the development of plants. The differentiation of different types of cells from the cultured cells is known as cytodifferentiation. When an undifferentiated callus re-differentiates into whole plant, it first undergoes cytodifferentiation.
