Mitosis
Part C
Term | Definition |
---|---|
Interphase | the cell is growing & devloping |
syntehtsis phase | the chromosomes replicat ein the cucleus x 2 chromosomes |
growth phase | cell is growing and developing its organelles |
prophase | centrioles move to opposite poles - nucelsu evelope dissapears - chromosomes coil up into visible structures |
metaphase | spindle fibres attach onto the chromosome and liene them up in the middle - spindle fibres attach on the the centriomeres |
anaphase | - spindle fibres retract and pull 1/2 the chrromosomes towards each centriole |
telophase | spindle fibres areback in the centrioles - nuclear enveliopes starts to form back around both sets of chromosomes - chromosomes uncoilt o become chromatin |
cell checkpoints | cell checkpoint - not enough nutrients to grow |
cytokinesis | cell membranes, pinches off in the middle & separates into 2 daughter cells |
apoptosis | cells die when it is too old to function |
cancer cells | - can undergo mitosis an ulmimited number of times |
tumor | cells that clump together due to an uncontrollable urge to divide |
