Redistribution loses the acquired energy of differentiation by different cells. It allows different cells to function as specialized cells in the plant body. Typically, after preparing the plant body for structural differentiation, the differentiated cells return to a regenerated form, performing a specific function.
For example, a divided vascular cambium also divides between the second xylem and the phloem after cell division. However, cells in the second xylem and the second phloem are unable to maintain cell division and after maturation, these cells perform functions that combine food processing and water while providing structural integrity to plant structure.
The production of different cells/tissues that lose the ability to differentiate is called differentiated cells/tissue and event redistribution.
However, plant growth is open, and even plant diversity is open, because, for example, the same apical meristem cells form xylem phloem, fibers, etc., cells/tissues from the same meristem have different properties in maturation. The final structure in the maturation of a cell/tissue from the same meristem is determined by the location of the cell internally.
When new cells are formed from different tissues that act as meristems, the cells lose their ability to continue dividing and separating. Eventually, they mature into the functions of the plant body. The second xylem and the second phloem are excellent examples of the process of redistribution. The separated vascular cambium separates continuously to produce the second xylem on the inside and the second phloem on the outside. The second phloem and the second xylem cells lose their ability to continue dividing; instead, they become mature enough to perform certain bodily functions, including the transport of food and water, respectively. Phelloderm is a second layer of tissue produced by dedifferentiated cork cambium. Similar to the second xylem and phloem, phelloderm cells lose their ability to continue dividing but grow to perform certain functions such as reducing dehydration and preventing germs from invading the plant body due to the destruction of the epidermis.
Summary – Dedifferentiation vs. Redifferentiation
Redifferentiation is the process of maturing different cells to perform certain functions and lose their ability to divide again. Eg. the Composition of the second phloem, the second xylem, the second cortex, cork, etc. from interfascicular cambium and cork cambium.
Plant cells taken from meristems such as root apex, shoot apex, and cambium are isolated. Separately, they are converted into structures that perform certain functions of the plant body. Once isolated, these cells lose the ability to differentiate continuously. Dedifferentiation is a process that occurs under certain conditions in which plant cells are already isolated and divide their energy. When different tissues produce new cells, the produced cells lose their ability to continue dividing but mature to perform specific functions. This process is known as redifferentiation. This is the difference between dedifferentiation and segregation.
Dedifferentiation vs. Redifferentiation
In plants, segregation is a process in which cells are derived from apical roots and shoot-apical meristems and cambium separate and mature to perform specific functions. Once separated, living cells lose their ability to divide. However, under certain conditions, this ability for continuous separation can be recovered. The process by which mature cells reverse their isolation and attain pluripotentiality is known as dedifferentiation. The process by which different cells lose their ability to differentiate and also to specialize in functioning by transforming into a permanent tissue is known as redistribution. This is the main difference between dedifferentiation and redistribution.
Redifferentiation in plant tissue culture:
Redifferentiation also called budding in plant tissue culture, may begin any time after the first callus cell forms. In this process of tissue called an organ, primordia are differentiated from a single or a group of callus cells.

FAQs
What do you understand by the word divide?
Dedifferentiation is a process that causes mature cells to reverse their isolation and gain pluripotential. Redifferentiation is a process in which different cells lose the ability to differentiate and become specialized in function by transforming themselves into permanent tissue.
What kind of difference is seen in plants?
The Distribution Process in Plants: Plant separation is a process in which the root system cells shoot an apical meristem and the Cambium matures to perform certain functions. In a very simple way, we can say that cell division is a process in which a cell changes from one cell to another.
What is the regeneration of plant culture?
It is a re-exchange process in which different cells once again lose their ability to separate and mature to perform a specific task.
