Question

practice types of cellular transport
read each statement and place a check - mark in the column of the correct choice
part 1: passive vs. active
1 materials move down a concentration gradient
2 requires energy
3 materials move against the concentration gradient
4 materials move from high concentration to low concentration
5 tends to move small, nonpolar molecules across the cell membrane
6 tends to move large, polar molecules across the cell membrane
part 2: types of transport (check all columns that apply. some may be checked more than once.)
7 moves water
8 involves a protein channel
9 moves small particles like o₂ and co₂
10 involves a vesicle
11 moves ions
part 3: types of osmotic solutions (some columns may be checked more than once.)
12 causes cell to shrivel
13 same osmotic concentration as the cell
14 higher osmotic concentration than the cell
15 causes water to move into the cell

Explanation:

Part 1 distinguishes passive (no energy, down gradient) vs active (energy, against gradient) transport. Part 2 identifies specific transport types by their characteristics. Part 3 classifies osmotic solutions by their effect on cells.

Answer:

Part 1:

1. Passive
2. Active
3. Active
4. Passive
5. Passive
6. Active

Part 2:

1. Osmosis
2. Facilitated Diffusion, Molecular Pumps
3. Diffusion
4. Endocytosis, Exocytosis
5. Facilitated Diffusion, Molecular Pumps

Part 3:

1. Hypertonic Solution
2. Isotonic Solution
3. Hypertonic Solution
4. Hypotonic Solution
