Document Summary

Prokaryotic do not have nuclear membrane or compartmentalization of organelles. Eukaryotic have a true, membrane bound nucleus and organelles. These include plants, animals, unicellular and multicellular fungi, and unicellular protozoans. Plasma membrane surrounds the cell surface and separates the intracellular fluid from the extracellular fluid. Cell interior consists of the nucleus and the cytoplasm: nucleus contains the genetic material, cytoplasm everything outside the nucleus. Includes the cytosol (gel-like fluid) and the organelles. Functions: physical barrier maintains difference in fluid composition between icf and. Ecf: cell-to-cell communication receptors bind signaling molecules arriving at the cell surface, structural support specialized connections exist between the plasma membranes and the extracellular materials, transport the movement of ions, waste, and secretory products. Composition: double layer of lipid molecules, embedded proteins, different ratios of lipids and proteins in each membrane. Fatty acids: carboxylic acid groups with a long chain of hydrogen and carbons, saturated = no double bonds, unsaturated = one or more double bonds, nonpolar.
