प्रश्न
Both animals and plants grow. Why do we say that growth and differentiation in plants is open and not so in animals? Does this statement hold true for sponges also?
उत्तर
In animals, once one type of tissue is developed, it cannot be changed into another. Furthermore, all organs of the animal's body stop growing at a specific age. Plant growth, on the other hand, is indeterminate since a plant component can develop into an unlimited number of numbers. In plants, a senescent component is frequently replaced. If a need arises, differentiated cells in plants undergo dedifferentiation. Sponges are unusual animals in the animal realm. The growth of a sponge is open.
