- Nucleus- has a double membrane (envelope), nuclear pores, nucleoplasm, chrosomosomes and nucleolus
- Mitochondrian- double membrane, a cristae (inner memberane extension) and matrix (rest of the organelle)
- Chloroplasts-double plasma membrane, thylakoids which hold the chlorophyll and stroma
- RER- outer membrane, ribosomes present
- SER- more tubular than RER as no ribomsomes
- Golgi Apparatus- stack of membranes making up a flattened sac
- Lysosomes- formed from golgi vesicles containing enzymes
- Ribosomes- cytoplasmic granules, 80S (EUKARYOTIC)

- Allows the passage of large molecules out of the cell eg. mRNA
- Site of aerobic respiration and production of ATP
- Carries out photosynthesis
- Provides a pathway for the transport of materials as well as a large surface area for synthesis of proteins
- Store and transport lipids and carbohydrates
- Secrete carbohydrates, form lysosomes, add carbs to proteins to form glycoproteins
- Break down cells after they have died by releasing emzymes
- Site of protein synthesis
- Provides strength to prevents the cell bursting under pressure
- Support herbaceous plants by making them turgid
