cell-surface membrane - regulates the movement of substances into and out of the cell. it also has receptormolecules on it when allow it to respond to chemicals like hormones
nucleus - controls the cell's activities by controlling the transcription of DNA. DNA contains instructions to make proteins. the pores allow substances e.g. RNA to move between the nucleus and the cytoplasm. the nucleolus makes ribosomes
mitochondria - the site of aerobicrespiration, where ATP is produced. they're found in largenumbers in cells that are very active and require a lot energy
chloroplast - the site where photosynthesis takes place. some parts of photosynthesis happen in the grana and other parts happen in the stroma (a thickfluid found in the chloroplasts)
golgi apparatus - processes and packages new lipids and proteins. it also makes lysosomes
golgi vesicles - stores lipids and proteins made by the golgiapparatus and transports them out of the cell (via the cell-surface membrane)
lysosome - contains lysozymes, digestive enzymes be used to digestinvadingcells or to breakdownwornoutcomponents of the cell
ribosome - the site where proteins are made
rough endoplasmic reticulum - folds and processes proteins that have been made at the ribosomes
smooth endoplasmic reticulum - synthesises and processes lipids
cell wall - supports cells and prevents them from changing shape
cell vacuole - helps to maintain pressure inside the cell and keep the cell rigid. this stops plants from wilting. also involved in the isolation of unwantedchemicals inside the cell
