- cells
- tissue
- organ
- organ system
Difference between unicellular and multicellular
- unicellular- single celled organism
- multicellular- multi celled organisms
cell wall
supporting layer around of the cell membrane in plants
cell membrane
regulates what enters and leaves the cell
differences between prokaryotes and eukaryotes
- prokaryotes are bacteria; eukaryotes are plants, animals, fungi
- prokaryotes don’t have a nucleus; eukaryotes do have a nucleus

- cells are the basic unit of structures and functions in living things
the diffusion of water through a selectively permeable membrane
osmosis
the process of when particles tend to move from an area with high concentration to an area with low concentration
diffusion
the diffusion of glucose across the membrane
facilitated diffusion

permeable- a substance can be pass through the membrane
impermeable- a substance cannot be pass through the membrane
how are factories and Golgi bodies similar?
