- The cell theory states that all living things are made of cells, cells are the basic unit of life, and all cells come from pre-existing cells.
- Prokaryotic cells lack a nucleus and membrane-bound organelles; an example is bacteria.
- Eukaryotic cells have a nucleus and other membrane-bound organelles; examples include plant and animal cells.
- Animal cells contain organelles such as the nucleus, mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, and cytoplasm.
- Plant cells have all the organelles found in animal cells plus a cell wall, chloroplasts, and a large central vacuole.
- The five kingdoms of life are Monera (prokaryotes), Protista, Fungi, Plantae, and Animalia.
- The endoplasmic reticulum is involved in protein and lipid synthesis and transport within the cell.
- Organelles work together to maintain cellular functions; for example, the nucleus directs protein synthesis, ribosomes build proteins, and the Golgi apparatus modifies and packages them for transport.
