maintains shape of cell
mitochondria
site of cellular respiration
cytoplasm
medium where chemical reactions occur

site of protein synthesis
plasma membrane
separates contents from external environment
smooth e.r
synthesises lipids
rough e.r
transports proteins
lysosomes
digestive compartment
centrioles
form spindle fibres during cell division
golgi apparatus
sorts and packages proteins into secretory vesicles
