Answer:
there are two types of cell one eukaryotic cell that have true nucleus (genetic material enclosed in membrane) and membrane bounded organelles and other is prokaryotic cell that donot have have true nucleus (genetic material dispersed in cytoplasm) and membrane bounded organelles.
similarities between PC and EC is that both contains cell membrane, ribosomes (not a membrane bounded organelle) .
examples of PC are bacteria , paramecium,fungi etc
examples of EC are plant and animal cells
there are two names for cell membrane i.e plasmalemma, cell surface membrane,
selectively permeable or semipermeable means cell only allows those material to pass through its cell membrane which it needs.this cell'ability is important because to protection against the poisonous substance and to maintain cell needs .
