How are the growth and development of a baby related to the process of mitosis? Mitosis regulates hormonal balance. Mitosis is relevant only to plants. Mitosis is a means of adding new cells. weight is increased by adding new cells.

Mitosis is a means of adding new cells. weight is increased by adding new cells.

Why don't blue-green algae and bacteria reproduce by mitosis? Because they are not organisms. They are not cells. They only contain one chromosome. They contain two chromosomes.

They only contain one chromosome.

Match the following. 1. Reproduction in which the offspring are genetic copies of the parent 2. Discreet units of chromatin which appear during cell division 3. The cell produced as a result of cell division 4. Having chromosomes in homologous pairs 5. Chromosomes that are the same in size, shape, and control the same characteristics 6. Cell division in which two daughter cells are genetic copies of the parent cell 7. Cell division by means of mitosis 8. A single individual plant or animal 9. The cell which begins the process of cell division __parent cell __chromosome __mitotic division __asexual reproduction __diploid __mitosis __daughter cell __homologous chromosomes __organism

9. parent cell 2. chromosome 7. mitotic division 1. asexual reproduction 4. diploid 6. mitosis 3. daughter cell 5. homologous chromosomes 8. organism

How does mitosis differ in plants and many animals? additional numbers of cells is not needed in most animals after maturity animals need cell repair, plants do not plants usually continue to grow throughout their existence mitosis relates to plants, meiosis relates to animals

additional numbers of cells is not needed in most animals after maturity plants usually continue to grow throughout their existence
