The cellular structures that are the machines that essentially build proteins needed for the cell to grown and survive, would be the ribosomes, these small granule like organelles are found throughout the cell, whether they be freely floating in the cytoplasm of the cell or attached to the endoplasmic reticulum. They are the site for where the tRNA's complementary base pair their anticodons to the codons present on the mRNA strand.
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
The offspring would have genes from both parents instead of just one so it so it would have a better chance at adapting to their environment and survive as a species
