1. Why is cell division essential to living things?
Ifk

As living things grow, some cells die or become damaged and need replacements. Some single-celled organisms use a type of mitosis as their only way to reproduce. In multi-celled organisms, cell division allows individuals to grow and change by expanding the number of total cells in the host.

it allows a living being to replace dead, old or damaged cells, and it also helps some organisms become bigger

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
