1.	Which of the following processes lead to formation of callus in plant tissue culture carried out in a laboratory?(a) No differentiation(b) Dedifferentiation(c) Differentiation(d) RedifferentiationI have been asked this question by my school teacher while I was bunking the class.The doubt is from Plant Growth and Development in portion Plant Growth and Development of Biology – Class 11
Answer» The correct choice is (b) Dedifferentiation Easiest explanation: Dedifferentiation leads to FORMATION of cork cambium and interfascicular cambium. Dedifferentiation is the PHENOMENON that leads to regaining the lost capacity of cells or TISSUES of plants to divide under special conditions. Differentiation is the division and growth of cells in order to attain maturity. Redifferentiation is the maturation of dedifferentiated cells thereby specializing for a particular function. Development INCLUDES all the CHANGES undergone by a living plant from seed emergence to death.
