Define growth, differentiation, development, dedifferentiation, redifferentiation, determinate growth, meristem and growth rate.
(a) Growth It is an irreversible and everlasting manner, performed through an growth withinside the length of an organ or organ elements or even of an person mobileular. (b) Differentiation It is a manner wherein the cells derived from the apical meristem (root and shoot apex) and the cambium undergo structural modifications withinside the mobileular wall and the protoplasm, turning into mature to carry out particular functions. (c) Development It refers back to the diverse adjustments taking place in an organism throughout its lifestyles cycle - from the germination of seeds to senescence. (d) De-differentiation It is the method wherein everlasting plant cells regain the energy to divide below sure conditions. (e) Re-differentiation It is the system wherein de-differentiated cells turn out to be mature once more and lose their ability to divide. (f) Determinate boom It refers to restricted increase. For example, animals and plant leaves prevent developing after having reached maturity. (g) Meristem In plant life, increase is confined to specialized areas wherein lively mobileular divisions take place. Such a vicinity is called meristem. There are 3 styles of meristems - apical meristem, lateral meristem, and intercalary meristem. (h) Growth rate It may be described because the extended boom in vegetation according to unit time.
