Answer:
Meiosis allows reproduction to happen and mitosis allows the growth and development of the organism. All of this contributes to the survival of the individual and the species.
Explanation:
The importance of mitosis is that it provides the growth and development of our body, and also acts by replacing lost cells. Meiosis, on the other hand, is fundamental for the maintenance of the life of multicellular beings, because it is through it that the reproduction cells are formed.
Moreover, mitosis is important because it generates daughter cells identical to the mother cell, acting on vegetative processes such as regeneration, hypertrophy. Meiosis is already responsible for the genetic variability of the offspring, and is therefore more evolutionarily adaptive, and, therefore, used in the gametogenesis of many species (Not all, as is the case with plants, very important multicellular beings that form the gametes by mitosis, although they form the spores by meiosis.).
