GOOD LUCK!!!

1) Name of the process by which vesicles containing cell products move towards the cell membrane and expel their contents into the extra-cellular fluid.

3) The bursting of an animal cell due to osmosis.

4) The spontaneous movement of particles from an area of high concentration to an area of low concentration

5)The fluid bathing the outside of a cell.

6) Type of solution where cytolysis occurs

7) Microscope that uses beams of electrons instead of light to produce
Images.

8) The cell membrane’s bilayer is composed mainly of this type of molecules.

9)Since the phospholipid bilayer has a fluid consistency and is studded with protein molecules, this is the name of the model representing it.

10) The steady state that results from maintaining near-constant conditions in the internal environment of a living thing

11) A cell that is permeable to some substances, like water, but not to others

12) What is the difference in concentration between two regions called?

13) The diffusion of water across a selectively permeable membrane.

14) The process of moving substances against their concentration gradient

(ions) to pass through

16) The most specific type of endocytosis.

17) The ability to clearly separate details.

18) Cell “drinking”.

19) Cell “eating”.

20) Small spherical structure formed by pinocytosis, containing E.C.F

21) Type of solution where crenation may occur.

22) Type of solution where plasmolysis may occur.

23) Type of solution where plants are more likely to wilt.

24) Type of solution where turgor pressure decreases.

25) Type of solution where turgor pressure increases.

26) Type of solution where dynamic equilibrium exists
