1. The process by which water moves across a membrane is called

A. Osmosis

B. Resolution

C. Active transport

D. Exocytosis

2. Some substances but not others can cross the

______________________________________ membrane of a cell.

Match the term with its definition by writing the letter of the correct definition in the right

column on the line beside the term in the left column.

3. _____ osmosis a. the process by which large molecules are engulfed by a cell

4. _____ exocytosis b. the process by which molecules tend to move from an area

of higher concentration to an area of lower concentration

5. _____ diffusion c. the process by which large molecules are expelled from a

cell.

6. _____ endocytosis d. the process by which water moves across a semi-permeable

membrane.
