- microtubles
- hollow rods of protein, (e) making up part of cytoskeleton, involved in cell contraction.
- gen
- origin, development.
- mitosis
- replication of chromosomes, production of 2 nuclii in 1 cell, usually followed by ctokinesis.
- (e)
- organism whose membrane and nucleus are enclosed protist,fungi, plant or animal.
- (p)

- cell theory
-
1. All living things are made of 1+ cells.
2. Unit of structure and function in all organisms.
3. All cell come from preexisting cells. - Mitosis and Cytokinesis
- prophase, metaphase, anaphase, telophase.
- cytoplasm
- entire contents of cell,except nucleus.
- geo
- earth
- diffusion
- movement of substance down it's concentration gradient.
- mitochondria
- organelle, (e) carry on cellular respiration, release energy, store ATP.
- osmosis
- movement of water across membrane.
- cytokinesis
- division of the cytoplasm of the cell after cell division.
- cytosol
- gelatin like portion of cytoplasm, bathes organelles of the cell.
