| a layer of carbohydrate moleclues bonded to the phospholipids and protiens of a plasma membrane | Glycocalyx |
| Molecule composed of 2 fatty acids and a phosphate- containin groupo bonded to the three carbons of a glycerol molecule | phospholipid |
| cytoplasm filled extensions of the cell ranging from filameontous to blunt finger like processes | pseudopods |
| what are the 3 principal types of connections between cells? | desmosomes, tight junctions, and gap junctions |
| what junction completely encircles the epithelial cell near its upper end and joins it securely to the adjecent cells? | Tight junctions |
| what type of junction is a patch for interlocking protiens that hold cells together at a specific point | Desmosome |
| formed by a ring of 6 protiens arranged( like segments of orange) | Gap junctions |
| what is the process in which hydrostatic pressure forces fluid through a selectively permeable membrane | filtration |
| what is the net movement of particles from high to low places of concentration | Simple diffusion |
| what is the net movement of water through a selectively permeable from the side where there is relatively low consentration of soludes to the side where there is high solute concentration? | Osmosis |
