|
Mitosis |
Portion of the Mitotic phase in which the nucleus divides |
|
|
Mitotic Phase |
Cell reproduces during this phase Follows interphase, shorter than interphase |
|
|
Results of cell division |
Reproduction, growth, replacement, repair |
|
|
Cytokinesis in a plant cell |
New cell wall (cell plate) starts to grow and forms from vesicles in the middle of the plant cell. Growth of the cell plate continues into two new cells are formed |
|
|
Daughter Cells |
Two new cells that are formed as a result of mitosis and cytokinesis |
|
|
About 24 hr |
Length of human cell cycle |
|
|
Interphase |
Period during the cell cycle of a cell's growth and development. Cell spends most of its life in interphase. |
|
|
Metaphase |
Chromosomes line up in single file in the middle of the cell |
|
|
Centromere |
Center structure that holds sister chromatids together (looks like a knot) |
|
|
Chromatin |
Long thin strands of DNA |
|
|
4 Phases of Mitosis |
1. Prophase 2. Metaphase 3. Anaphase 4. Telophase |
|
|
Chromosome |
Coiled up strands of DNA |
|
|
Cytokinesis |
Portion of the Mitotic phase in which the cytoplasm and it's contents divide
|
|
|
Cytokinesis in an animal cell |
Cell membrane squeezes together around the middle, forming a crease (furrow) in the center of the cell Furrow pinches together and divides the cell into two new ones |
|
|
2 stages of the Mitotic phase |
1 - Nucleus divides (mitosis) 2- Cytoplasm divides (cytokinesis |
|
|
Anaphase |
- Sister chromatids separate - Spindle fibers shorten and begin to pull chromatids to opposite sides of the cell - cell gets longer |
|
|
3 stages of the interphase |
1 - Rapid growth and copying of membrane bound organelles (G1) 2- Copying of DNA (S) 3- Preparation for cell division (G2) |
|
|
Cell Cycle |
Cells in an organism go through a cycle of growth, development, and division |
|
|
Sister Chromatids |
Two identical chromosomes, make up a duplicated chromosome |
|
|
Telophase |
- Nuclear membrane forms around the chromatid -Chromosomes begin the uncoil - Spindle fibers begin to breakdown - two identical nuclei form |
|
|
Mitotic phase creates |
2 identical new cells, the original cell no longer exist |
|
|
Prophase |
- Copied DNA coils up (condenses) into chromosomes - Nucleolus disappears - nuclear membrane breaks down - spindle fibers begin to form |
