Question | Answer |
---|---|
what are the stages of the cell cycle? | G1,Synthesis,G2,Mitosis |
How did the cell advance? | Originally there were only two parts in the cycle they were inter phase and mitosis |
why are there 3 parts of inter phase | cells carry out there normal functions then undergo growth and then grow some more and prepare for cell division |
what happens during G1 | the increases in size and organelle's increase in number |
why does a cell go through synthesis | to make a copy of cell DNA and nucleus to make a new cell |
what happens during G2 | to out normal functions and more growth occurs |
what are the stages of mitosis | the stages of mitosis is mitosis and cytokinesis |
What happens at the end of mitosis | A new cell is duplicated and now have 2 cells |
why do cells grow at different rates | if a cell does not have a cell membrane,organelles and cytoplasm the cell divides much faster |
why does everyone's cell cycle different | everyone's cell cycle is different because of the rate of growing and your brain singals. |
why is the cell size important | if the cell is too small the cell may not live and die |
why do chromosomes condense at start of mitosis | chromosomes must condense to be divided into 2 nuceli. |
what are all the stages of the cell cycle | G1,Synthesis,G2,Mitosis, pro-phase meta-phase ,anaphase, teleophase and cytokinesis |
why does DNA stay tight | DNA stays tight to wrap around new organizing proteins |
How does a cell cycle work for a plant cell | During cytokinesis in a plant cell the membrane can not pinch in ward due to the cell wall |
