Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF- Dedifferentiation is the process by which mature, differentiated cells revert to a less specialized, more embryonic state. This reversion allows the cells to regain meristematic activity, which is essential for forming a callus in plant tissue cultures.
- During dedifferentiation, cells lose their specialized functions and gain the ability to divide and form new tissues. This is a crucial step in plant regeneration and wound healing.
- Dedifferentiation is typically induced by plant hormones such as auxins and cytokinins, which stimulate cell division and growth.
- Differentiation is the process by which unspecialized cells become specialized into specific cell types. This is the opposite of dedifferentiation, as it involves cells acquiring distinct functions rather than reverting to a meristematic state.
- Redifferentiation refers to the process by which dedifferentiated cells specialize again into a new cell type. This is a subsequent step to dedifferentiation and is essential for the formation of specific tissues from the callus.
- Cytodifferentiation is the process of differentiation at the cellular level, where cells develop specific structures and functions. It is not the process by which cells revert to a meristematic state to form a callus.
