Document Summary
Weightlifting and muscles get larger: hyperplasia: cells grow in numbers, ex. Developing feet callus: can be normal, development refers to function changes, (cid:862)differentiations(cid:863) in text, 9. ) Good for viewing small things: scanning electron microscope (sem) uses a specimen coated with vaporized metal (usually gold) where the electron beam strikes the specimen and discharges secondary electrons form the metal coating. Egg cells and white blood cells: discoid: disc-shaped. Red blood cells: fusiform: spindle or toothpick shaped. Cytoplasm: the material enclosed by the plasma membrane: contains the cytoskeleton, a supportive framework of protein filaments and tubules. If too high, cholesterol in the membrane can inhibit the action of its enzymes and other proteins: about 5% of lipids are glycolipids: Phospholipids with short carbohydrate chains bound to them. Only on the extracellular face of the membrane: plasma membrane can self-repair, membrane proteins: Integral protein: penetrate at least partially into the phospholipid bilayer.
