Passive transport (no energy required)
- Diffusion: simple diffusion — movement of molecules from an area of higher concentration to an area of lower concentration until equilibrium is reached.
- Facilitated diffusion: movement of molecules down their concentration gradient through membrane proteins (channels or carrier proteins); no ATP required.
- Osmosis: diffusion of water across a semipermeable membrane from a region of lower solute concentration (higher water potential) to a region of higher solute concentration (lower water potential).
Difference between hypertonic and hypotonic environments
- Hypertonic: solution with a higher solute concentration than the cell — water leaves the cell; cell shrinks (crenation/plasmolysis).
- Hypotonic: solution with a lower solute concentration than the cell — water enters the cell; cell swells and may burst (lysis).
What is mitosis?
- Mitosis is the process of nuclear division in eukaryotic cells that produces two genetically identical daughter nuclei (and, with cytokinesis, two daughter cells). It preserves chromosome number and is used for growth, tissue repair, and asexual reproduction. (Major stages: prophase, metaphase, anaphase, telophase.)
