cell biology

osmosis - 

• the movement of water molecules across a partially permeable membrane from a higher water concentration to a lower water concentration.

diffusion - 

• The spreading out of particles from an area of higher concentration to an area of lower concentration.
• Bigger concentration gradient = faster diffusion rate.

cells - 

• prokaryotic -  Smaller and simpler E.g. bacteria.
• Eukaryotic - Include animal and plant cells. Complex.
• Animal - Nucleus, Mitochrondria, Cell membrain,Ribosomes, Cytoplasm.
• plant - …
