Bi 121 GRCC LAB exam 1
1. Diffusion Movement of molecules from an area of higher concentration to an area of lower
concentration. (form of passive transport)
2. selective perme- A property of a plasma membrane that allows some substances to cross more easily
ability than others.
3. passive transport Requires NO energy, Movement of molecules from high to low concentration,
Moves with the concentration gradient
4. concentration A difference in the concentration of a substance across a distance.
gradient
5. isotonic denoting or relating to a solution having the same osmotic pressure as some other
solution, especially one in a cell or a body fluid.
6. Hypertonic Having a higher concentration of solute than another solution. (shrinks)
7. Hypotonic Having a lower concentration of solute than another solution (swells)
8. Solute A substance that is dissolved in a solution.
9. Osmosis Diffusion of water through a selectively permeable membrane (passive transport)
10. active transport Energy-requiring process that moves material across a cell membrane against a
concentration difference
11. Crenation This happens when a cell shrinks and shrivels; can result in cell death if severe.
12. -lysis breakdown of a cell caused by damage to its plasma membrane
13. simple diffusion movement of a solute from an area of high concentration to an area of low
concentration
14. Superior Plane everything above the transverse line (above the waist)
, Bi 121 GRCC LAB exam 1
15. Inferior Plane everything below the transverse line (below the waist). Opposite of superior plane.
16. Anterior (ventral) front of the body
17. Posterior (dorsal) back of body
18. Medial Toward the midline of the body
, Bi 121 GRCC LAB exam 1
19. Lateral Away from the midline of the body
20. superficial near the surface
21. Distal farther from the origin of a body part or the point of attachment of a limb to the
body trunk
22. deep (internal) Away from the body surface; more internal
23. Proximal Closer to the origin of the body part or the point of attachment of a limb to the
body trunk
24. serous mem- Membrane that lines a cavity without an opening to the outside of the body
brane
thin layer of tissue that covers internal body cavities and secretes a fluid that keeps
the membrane moist; also called serosa
