Explain in 2-3 lines each of the following terms with the help of examples taken from different plant tissues
? (a) Differentation,(b) De differenatiation ,(c ) Re- differentiation

Explanation

(a) Differentiation is permanent in size structure composition and function of cells tissue or rogans . For example the meristematic tissues in plants gives rise to new cells which mature and get differnetiataeedd into special tisseu or an organ of the plant e.g cells distal to root apical meristem form root cap , cell of the periphery form epiblema flolowed by corted endodermis , pericycle and vasuclar
(b) De differenctiation is the process of despeciallisation of differtiated cells so that they aganin become fiferentiated and able to dive e.g in dicot stem, the cortical cells get de differentiated and become meristematic to form cambium (interfascicular cambium and fascicular cambiums) ltrbgt (c ) Re- differentiation The cambium cells thus formed again re differentiation to form secondary cortex cells secondary xylem and phloem elements and phelloderm in case of secondary trowth of woody dicot plants
