1.A) Two main forms of cells exist: eukaryotic cells and prokaryotic cells. Prokaryotic cells are smaller and do not have membrane-bound nucleus or membrane- bound organelles‚ but do have: plasma membrane‚ cytosol and cytoplasm‚ and ribosomes. Prokaryotes contain much less DNA than eukaryotes and have circular chromosomes. Eukaryotic cells have information processing organelles‚ such as the nucleus which houses most of the cell’s DNA‚ and ribosomes which use information from DNA to produce proteins
