About Growth and Development
Embryonic development covers fertilization, cleavage, formation of the blastula and gastrula, germ layers, organ formation and differentiation. Regeneration describes the replacement of lost tissues or body parts, whereas ageing involves gradual cellular and physiological changes linked to reduced repair, altered metabolism and declining organ function.
