Let's go through the Cell Transport Review Worksheet step by step and solve each section with explanations.

Part 1: Complete the table by checking the correct column for each statement

We are given a table with statements about solutions (isotonic, hypotonic, hypertonic) and asked to check which type of solution causes each effect.

| Statement | Isotonic solution | Hypotonic solution | Hypertonic solution |
|---------|-------------------|--------------------|---------------------|
| Causes a cell to swell | | ✔ | |
| Doesn't change the shape of a cell | ✔ | | |
| Causes osmosis | ✔ | ✔ | ✔ |
| Causes a cell to shrink | | | ✔ |

#### ✔ Explanation:

- Hypotonic solution: Has lower solute concentration than the cell. Water enters the cell → causes swelling.
- Isotonic solution: Equal solute concentration inside and outside the cell → no net movement of water → no change in shape.
- Hypertonic solution: Higher solute concentration outside → water leaves the cell → causes shrinking.
- Osmosis occurs in all three because it is the movement of water across a membrane due to concentration differences — even if there’s no net movement (isotonic), osmosis still happens but balances out.

So the completed table should be:

| Statement | Isotonic solution | Hypotonic solution | Hypertonic solution |
|---------|-------------------|--------------------|---------------------|
| Causes a cell to swell | | ✔ | |
| Doesn't change the shape of a cell | ✔ | | |
| Causes osmosis | ✔ | ✔ | ✔ |
| Causes a cell to shrink | | | ✔ |

✔ Corrected and verified.

Part 2: Match the term with its correct description

Terms:
a. energy
b. facilitated diffusion
c. endocytosis
d. passive transport
e. active transport
f. exocytosis
g. carrier protein
h. channel protein

Now match each description:

1. Transport protein that provides a tube-like opening in the plasma membrane through which particles can diffuse
→ This describes a channel protein, which forms a pore.
✔ Answer: h

2. Is used during active transport but not passive transport
→ Energy is required for active transport but not for passive.
✔ Answer: a

3. Process by which a cell takes in material by forming a vacuole around it
→ That's endocytosis.
✔ Answer: c

4. Particle movement from an area of higher concentration to an area of lower concentration
→ This is passive transport (specifically diffusion).
✔ Answer: d

5. Process by which a cell expels wastes from a vacuole
→ That's exocytosis.
✔ Answer: f

6. A form of passive transport that uses transport proteins
→ This is facilitated diffusion (uses carrier or channel proteins).
✔ Answer: b

7. Particle movement from an area of lower concentration to an area of higher concentration
→ This requires energy → active transport.
✔ Answer: e

8. Transport protein that changes shape when a particle binds with it
→ This is a carrier protein (e.g., glucose transporter).
✔ Answer: g

✔ Final Answers for Part 2:

```
_H_ Transport protein that provides a tube-like opening... → h. channel protein
_A_ Is used during active transport but not passive transport → a. energy
_C_ Process by which a cell takes in material by forming a vacuole... → c. endocytosis
_D_ Particle movement from high to low concentration → d. passive transport
_F_ Process by which a cell expels wastes from a vacuole → f. exocytosis
_B_ A form of passive transport that uses transport proteins → b. facilitated diffusion
_E_ Particle movement from low to high concentration → e. active transport
_G_ Transport protein that changes shape when a particle binds → g. carrier protein
```

Part 3: Match the term with its correct description

Terms:
a. transport protein
b. active transport
c. diffusion
d. passive transport
e. osmosis
f. endocytosis
g. exocytosis
h. equilibrium

Descriptions:

1. The diffusion of water through a cell membrane
→ This is osmosis.
✔ Answer: e

2. The movement of substances through the cell membrane without the use of cellular energy
→ This is passive transport.
✔ Answer: d

3. Used to help substances enter or exit the cell membrane
→ This refers to transport proteins (like channels or carriers).
✔ Answer: a

4. When energy is required to move materials through a cell membrane
→ This is active transport.
✔ Answer: b

5. When the molecules of one substance are spread evenly throughout another substance to become balanced
→ This is equilibrium.
✔ Answer: h

✔ Final Answers for Part 3:

```
_E_ The diffusion of water through a cell membrane → e. osmosis
_D_ The movement of substances through the cell membrane without energy → d. passive transport
_A_ Used to help substances enter or exit the cell membrane → a. transport protein
_B_ When energy is required to move materials through a cell membrane → b. active transport
_H_ When molecules are spread evenly... → h. equilibrium
```
