Organisms make more of the species to keep them from going extinct >> Reproduction
Explanation:
Growth refers to the irreversible process by which organisms/tissues/cells increase in size and mass. Moreover, development can be defined as the progression from earlier to later maturation stages (e.g. fertilized ovule develops into a seed that will produce a mature tree). Cell replacement is a natural mechanism that occurs when cells become aged or in response to external/internal damage. During cell replacement, cells are produced from other cells by cell division. Finally, reproduction is a key biological process by which organisms (called parents) produce new genetically related organisms (i.e., offspring). According to the mode of transmission of genetic information, reproduction can be divided into sexual reproduction (offspring are different from parents) and asexual reproduction (offspring are the same as parents).
During interphase, the cell grows and the DNA replicates. After that there's the mitotic phase where the replicated DNA and the contents in the cytoplasm are sperated in a way that the cell divides.
