Surface area to volume ratio for cell growth. |
Surface area: Increase by a factor of four.
Volume: Increase by a factor of eight. |
|
|
Sexual vs. Asexual reproduction |
Sexual: Create a new organism (multicellular organisms).
Asexual: Create a copy of itself (split a mother cell into a daughter cell) (unicellular organisms). |
|
|
Stages of the cell cycle: |
1. Interphase -> Cell prepares for cell division (Mitosis): a.) Rapid growth b.) DNA Synthesis/replication c.) Centrioles replicate (prep. for cell division)
2. Mitosis -> Division of a cell's nucleus: a.) Prophase - Visable chromosomes/(-) nuclear envelope/doubled chromosomes/sister chromatids b.) Metaphase - Chromosomes move to the equator c.) Anaphase - centromeres split/sister chromatids pulled apart (going to opposite poles of the cell) d.) Telophase - two daugther cells are fromed/cells seperate in cytokinesis/nuclear membrane reappears
3. Cytokinesis -> Division of a cell's cytoplasm |
|
|
What is the purpose of mitosis? |
Allow for growth and repair of tissues. |
|
|
Possible causes of cancer: |
Radiation, certain chemicals, some hormones (e.g. increased estrogen levels), genes, etc.). |
|
|
How do embryonic cells differentiate into many types. |
Process of differentation -> A cell can become a precursor to a different type of cell |
|
|
Benefits of stem cell research. |
Repair damaged organs, help those with cancer, contribute to research, save people from death, etc. |
