Document Summary
Bacterial cells are prokaryotic and do not contain a nucleus or other membrane bound organelles. Our cells are eukaryotic and as shown in the diagram contain many compartments bounded by membranes. This is a general structure, showing similarities between cells, keep in mind they are not all the same and will vary in different tissues (bacterial cell something similar is a plasma membrane the green layer. Some have flagella, some are rod shaped) Ba(cid:272)teria (cid:272)ells do(cid:374)"t ha(cid:448)e (cid:373)e(cid:373)(cid:271)ra(cid:374)e (cid:271)ou(cid:374)d organelles but eukaryotic cells do (ex. nucleus is a membrane bound organelle which cells are encased in it) All cells are enclosed by a plasma membrane, which is a lipid bilayer (2 layers with their polar groups facing the aqueous environment on either side: purple balls depict polar area. Inside is polar, and the lipid parts stick together (hydrophobic and hydrophobic stick together; things facing the outside and water environment need to be polar)
