- Eukaryotic Cells
- true nucleus
- all organism (bar bacteria)
- Plasma Membrane
- phospholipid bilayer & proteins
- controls entry & exit of molecules
- Nucleus
- contains DNA
- can't escape through nuclear pores
- Nuclear membrane
- protects DNA
- DNA is wound around histones (proteins)
- Nucleoplasm
- contains chromatin
- Nucleolus
- makes rRNA
- protien
- makes rRNA
- Nuclear pores
- transport mRNA, rRNA & ribosomes
- controls all chemical reactions
- contains DNA

- network within a cell
- Rough ER
- studded with ribosomes
- synthesise proteins
- studded with ribosomes
- membrane channels
- cisternae
- Smooth ER
- no ribosomes
- processes lipids
- Ribosomes
- joins acids together to make proteins

- found in
- Cytoplasm
- RER
- in 2 sub-units
- small
- large
- joins acids together to make proteins
- Golgi Apparatus/Body
- modifies & packages
- protein
- lipids
- can add carbohydrate
- gylcoprotein

- bud off Golgi
- transport proteins to cell membrane
- fuse & release contents
- exocytosis
- fuse & release contents
- go to cytoplasm
- lysosomes
- "suicide bags"
