To get proficient on this test, you need to be able to:
□ Recognize the definitions of diffusion, osmosis, passive transport, active transport, exocytosis,
and endocytosis.
□ Identify diffusion, osmosis, passive transport, active transport, exocytosis, and endocytosis by
their pictures.
Ways to Study:
 Flashcards
 The practice questions below
 Vocabulary notes p. 75-77 in Science Notebook
 Textbook Chapter 4, section 1
Test Practice Questions:
1. Describe diffusion:
 Moves things into/out of the cell (circle one or both!)

Moves with/against concentration gradient (circle one)

For large/small molecules (circle one or both!)

Uses/does not use protein doorway (circle one)
2. Describe osmosis:
 Moves things into/out of the cell (circle one or both!)

Moves with/against concentration gradient (circle one)

For large/small molecules (circle one or both!)

Uses/does not use protein doorway (circle one)
3. Describe passive transport:
 Moves things into/out of the cell (circle one or both!)

Moves with/against concentration gradient (circle one)

For large/small molecules (circle one or both!)

Uses/does not use protein doorway (circle one)
4. Describe active transport:
 Moves things into/out of the cell (circle one or both!)

Moves with/against concentration gradient (circle one)

For large/small molecules (circle one or both!)

Uses/does not use protein doorway (circle one)
5. Describe endocytosis:
 Example of active/passive (circle one)

Moves things into/out of the cell (circle one or both!)

For large/small molecules (circle one or both!)
6. Describe exocytosis:
 Example of active/passive (circle one)

Moves things into/out of the cell (circle one or both!)

For large/small molecules (circle one or both!)
Identify each as diffusion, osmosis, passive transport, active transport, exocytosis or endocytosis.
