prokaryotic cells are smaller than eukaryotic cells and eukaryotic cells contain a nucleus, while prokaryotic cells don’t
what are plasmids
small, circular loops of DNA found free in cytoplasm

function of the nucleus is…
to control cellular activities
function of cytoplasm is…
first stage of respiration
function of cell membrane…
controls what goes in and out of the cell
function of ribosomes…
where protein synthesis happens
what does vacuole contain
cell sap
what is cell differentiation
the process which cells become specialised
advantages of using a light microscope
cheap, portable and easy to use
disadvantages of using an electron microscope
expensive, too big, need specific training
