Contains genetic material
Contains instructions for production of ppcs
Nucleus
Produces ribosomal subunits and assembles ribosomes
Nucleolus
Allows exit of mRNA after transcription = translation can occur in cytosol
Nuclear pore
Site of Link reaction, Krebs cycle and Oxidative Phosphorylation
Site of ATP production
Mitochondria
Site of lipid, carbohydrate and steroid hormone synthesis, storage and transport
SER
Site of protein and glycoprotein synthesis
Site of folding ppc into secondary or tertiary structure
Proteins packaged into vesicles
RER
Site of translation of mRNA
Ribosomes
Assembles ppcs into proteins
Packages proteins and lipids
Addition of glycocalyses and phosphate groups
Proteins sorted into vesicles
Golgi apparatus
Transports proteins and lipids within cell
Golgi vesicles
Remove unwanted cell structures, organelles and chemicals in cell
Role in phagocytosis and apoptosis
Lysosomes
Organise spindle fibres in nuclear division
Migrate to poles during prophase
Centrioles
Site of light independent stage of photosynthesis
Chloroplast
Supports cell, aids turgidity
Reservoir for water
Large permanent vacuole
Gives cell shape, supports cell, prevents bursting when water enters by osmosis
Cell wall
Transfers materials and chemicals between cells
Plasmodesmata
Possible site of aerobic respiration
Mesosome
Enable bacteria to adhere to each other or other surfaces
Pili
Enables motility and movement of bacteria
Flagellum
