transport | The Biology Corner - Free Printable

Let's solve this diagram step by step. This is a concept map about cell transport, and we need to fill in the blanks based on biological principles.

🔹 Step 1: Understand the overall structure

The diagram shows:
- Cell Transport is regulated by something.
- That regulator is made of proteins (as shown by the arrow pointing to a membrane with embedded proteins).
- Cell transport includes active and passive transport.
- Active transport requires energy and includes specific types.
- Passive transport involves water and includes movement from high to low concentration until equilibrium.

We'll go through each blank one by one.

🔹 Fill in the blanks:

#### 1. Cell Transport → regulated by → [ ]
This should be membrane proteins or more specifically, transport proteins.

But looking at the next box: "made of" → points to a membrane with proteins embedded.

So the first blank must be:
✔ Membrane proteins

> Because cell transport is regulated by membrane proteins.

---

#### 2. Membrane proteins → made of → [ ]
Already given: proteins → so this is correct.

---

#### 3. Cell Transport → includes → [ ] and [ ]
We already see active and passive are branches.

So the two boxes before them are:
✔ Active and Passive

Wait — actually, the diagram shows “which includes” branching into active and passive.

So the two top-level categories are active and passive.

But the leftmost blank above “active” is missing — it’s pointing to “requires”.

Let’s look carefully.

Actually, the diagram has:

```
Cell Transport
↓ regulated by → [Membrane Proteins] → made of → [Proteins]
↓ which includes
[ ] ←→ active ←→ passive
```

Wait — no, the structure is:

- Cell Transport → regulated by → [Box A] → made of → [Proteins]
- Cell Transport → which includes → [Active] and [Passive]

So the blank directly after “which includes” is not needed — it's split into two: active and passive.

But there's an empty box on the left side, connected to “requires” and leading to “active”.

So let’s trace:

---

#### 4. [Blank] → requires → active

What does active transport require?

✔ Energy (ATP)

So the blank is: Energy (or ATP)

> So: Energy → requires → active transport

---

#### 5. Active → includes → [ ] and [ ]

Active transport includes:
- Endocytosis
- Exocytosis
- Primary active transport (e.g., Na+/K+ pump)
- Secondary active transport (e.g., symporters)

But looking at the images below:

- The left image shows molecules being pulled into the cell via a vesicle → that's endocytosis
- The right image shows molecules moving out via vesicles → that's exocytosis

So the two types of active transport shown are:
✔ Endocytosis and Exocytosis

So fill in:
- First box under active: Endocytosis
- Second box under active: Exocytosis

> Note: There are other forms of active transport (like pumps), but since these two are illustrated, they’re likely the intended answers.

---

#### 6. Passive → includes → [ ]

Passive transport includes:
- Simple diffusion
- Facilitated diffusion
- Osmosis

But the diagram shows:
- One branch says: involves water
- And then a diagram showing water moving across a membrane (osmosis)

So this suggests:
✔ Osmosis

So the blank under "includes" for passive is: Osmosis

But wait — the diagram shows:
- Passive → includes → [Box] → involves → water

So the box is Osmosis

✔ Yes.

---

#### 7. Passive → includes → [ ] → where molecules move from high concentration to [ ] → until [ ]

This is describing diffusion.

So the first blank here (after "includes") is likely Diffusion.

But wait — it’s already split: passive includes Osmosis and another type.

Looking at the right side:

- Passive → includes → [Box] → where molecules move from high concentration to [ ] → until [ ]

And it shows a diagram of particles spreading from high to low concentration.

So this is simple diffusion or just diffusion.

But osmosis is a special case of diffusion involving water.

So perhaps:

- Passive includes: Osmosis and Diffusion

But the diagram only shows one "includes" box → maybe it's diffusion?

Wait — the layout:

```
Passive
↓ includes
[Box A] → involves → water → (osmosis diagram)
[Box B] → where molecules move from high conc → low conc → until equilibrium
```

Ah! So two types under passive:

- One is osmosis (involves water)
- The other is diffusion (molecules move from high to low)

So the second blank under "includes" is: ✔ Diffusion

Then:
- Diffusion → where molecules move from high concentration to → ✔ low concentration
- Until → ✔ equilibrium

---

#### 8. Final check:

Let’s now fill in all blanks:

---

✔ Completed Diagram:

```
Cell Transport
↓ regulated by → [Membrane Proteins] → made of → [Proteins]
↓ which includes
[Energy (ATP)] → requires → active
↓ includes
[Endocytosis] [Exocytosis]

passive
↓ includes
[Osmosis] → involves → water → (diagram of water movement)
[Diffusion] → where molecules move from high concentration
→ to → [low concentration]
→ until → [equilibrium]
```

📌 Summary of Answers:

| Blank | Answer |
|------|--------|
| Regulated by | Membrane proteins |
| Made of | Proteins (already filled) |
| Requires → active | Energy (ATP) |
| Active includes | Endocytosis and Exocytosis |
| Passive includes | Osmosis and Diffusion |
| Molecules move from high to → | low concentration |
| Until → | equilibrium |

💡 Explanation:

- Cell transport is controlled by membrane proteins (channels, carriers, pumps).
- Active transport needs energy (ATP) and includes endocytosis (bringing in materials via vesicles) and exocytosis (expelling materials).
- Passive transport does not require energy and includes:
- Osmosis: diffusion of water across a membrane.
- Diffusion: movement of molecules from high to low concentration until equilibrium is reached.

The diagrams support this:
- Left: Endocytosis (cell engulfing material).
- Right: Exocytosis (cell releasing material).
- Water movement: osmosis.
- Particle spread: simple diffusion.
