| Question | Answer |
|---|---|
| In multicellular ordanisms, what is the celldivision used for? | used for growth, development, and repair of the organism. |
| what is cell division controlled by? | dna |
| how does bacteria reproduce? | by a simple process called binary fission. |
| what are somatic cells? | general body cells. |
| what are gametes? | sex cells. |
| what do gametes consisit of? | consisting of eggs in females and sperm in males |
| what is mitosis? | specifically the process of division of the chromosomes |
| what is cytokenisis? | officially the process of division of the cytoplasm to form two cells |
| what do centriols consist of.? | consist of nine sets of three microtubules |
| where do centrioles occur? | occur in animal cells only |
| What are the stages of mitosis? | (interphase), prophase, metaphase, anaphase, and telophase |
| What happens during interphase? | may appears to be a “resting” stage, but cell growth, replication of the chromosomes, and many other activities are taking place during this time. |
| What happens during prophase? | the chromosomes start to coil, shorten, and become distinct |
| what is metaphese characterized as? | characterized by the lining up of the chromosomes along the equator of the cell or what is called the metaphase plate. |
| what happens during anaphase? | sister chromatids separate at the centromeres, thus can now be called chromosomes. These are pulled to the poles of the cell by the mitotic spindle |
| what happens during telophase? | new daughter nuclei and nuclear envelopes start to reform and the chromosomes uncoil |
| what are the products of mitosis? | daughter cells that are genetically identical to parent cell with same set of chromosomes. |
| How many cells does mitosis produce? | 2 |
| Are daughter cells haploid or diploid? | diploid |
| What kind of cells does mitosis produce? | body cells. |
| What kind of reproduction does mitosis use? | asexual reproduction. |
