📚 Practice ConceptDefine growth, differentiation, development, dedifferentiation, redifferentiation, determinate growth, meristem and growth rate.
Which scenarios illustrate integration of growth, development, and differentiation? 1. Parenchyma cells dedifferentiate to form cork cambium, later redifferentiate into cork. 2. Auxins induce parthenocarpic fruit in tomato, ethylene accelerates ripening. 3. GA promotes bolting in cabbage before flowering, followed by ABA-induced seed dormancy. 4. Root cap cells from apical meristem undergo rapid senescence.
