Question

For single celled, asexual organisms, cell division is used for ___.For multicellular organisms, simple cell division is used for___
a.growth and repair; growth, repair, and reproduction
b.reproduction; growth and repair
c.reproduction; growth, repair, and reproduction
d.growth, repair, and reproduction; growth, repair, and reproduction

Answer 1

Answer:

c. reproduction; growth and repair

Explanation:

When a cell divides, it creates new cells. In asexual single-celled organisms it used for reproduction only. However, in multicellular cells it is usually used for growth and repair. This is because multicellular organisms have levels of organisation (cells --> tissues --> organs --> organ systems --> organisms). The cells are the smallest components of the organism. So when a cell divides it can replace cells to repair tissues or organs. Single-celled organisms can't repair tissues and organs because they don't have any - they are made up of only one cell.
