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.
