| Osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's partially permeable membrane. |

| What are the 5 steps of Prophase? |
|
Definition
- Chromosomes visible (chromatids)
- Centrioles migrate to the poles
- Nuclear membrane disappears
- Nucleolus disappears
- spindle forms[image]

Term
| What happens during Telophase? |
|
Definition
- Chromosomes disappear -- Chromatin
- nuclear membrane reforms
- nucleoli reappears
- spindle disappears
- centrioles duplicate[image]

Term
|
Definition
- Each of the 2 thread-like strands into which a chromosome divides longitudinally during cell division.
- Each contains a double helix of DNA

| Cell division in plants: Name 2 big differences from animal cells? |
|
Definition
- A plant cell DOES NOT have centrioles that form
- A plant cell will produce a CELL PLATE during telophase, which will mature during cytokinesis, that will fully form to officially divide the cell. Basically, this CELL PLATE forms the new cell wall of the daughter cell.
