Thu, february 11 - lecture 10 mitochondria part 2 (cell death) Slide 4 cells can grow, there needs to be a limit, and it is advantageous to be able to get rid of cells. Slide 5 there are cell cycle checkpoints where they check cells to make sure that they are healthy, being useful. etc. Slide 6 each nematode identical number of cells, making them easy to track (very unlike humans), limited number of cells makes it easy to compare it to organisms with more cells. Slide 7 when they develop into adult nematodes, the same 131 cells apoptose every time. Necrosis: the cell swelled and membrane bursts (as soon as it swells it is inevitable that the cell will die. Apoptosis: the cell shrinks and breaks into fragments, Apoptosis is a very clean process and does not effect outside environment, whereas necrosis is when the membrane bursts, allowing all it"s inner substances out into the environment, affecting other cells.
