Let's solve the concept map step by step based on the topic:
Transport Through Membranes.
We are given the following words/phrases to use:
- simple diffusion
- energy
- bigger concentration
- lower concentration
- osmosis
- passive
- facilitated diffusion
---
Step 1: Understand the Concept Map Structure
The main idea is
"Transport through membranes", which branches into two types:
1.
Active transport
2.
Passive transport
So, we can fill in:
-
4. passive (since active and passive are the two main categories)
---
Left Side: Active Transport
Active transport:
- Requires
energy → so
1. energy
- Uses
transport proteins
- Moves materials
from a region of lower concentration to a region of
higher concentration (against the gradient)
So:
-
2. lower concentration
-
3. higher concentration
> Note: "bigger concentration" is likely meant to be "higher concentration", and vice versa.
---
Right Side: Passive Transport
Passive transport:
- Does
not require energy
- Examples include:
-
Simple diffusion
-
Facilitated diffusion
-
Osmosis
So:
-
5. simple diffusion
-
6. facilitated diffusion
-
7. osmosis
These all move materials from a region of
higher concentration to a region of
lower concentration (down the concentration gradient).
So:
-
8. higher concentration
-
9. lower concentration
---
Final Answers:
1.
energy
2.
lower concentration
3.
higher concentration
4.
passive
5.
simple diffusion
6.
facilitated diffusion
7.
osmosis
8.
higher concentration
9.
lower concentration

Explanation of Concepts:
-
Active transport: Moves substances against their concentration gradient (from low to high concentration). Requires energy (usually ATP) and transport proteins (e.g., sodium-potassium pump).
-
Passive transport: Moves substances down their concentration gradient (from high to low concentration), no energy required.
-
Simple diffusion: Small nonpolar molecules (like O₂, CO₂) diffuse directly through the membrane.
-
Facilitated diffusion: Polar or charged molecules (like glucose) use channel or carrier proteins.
-
Osmosis: Diffusion of water across a semipermeable membrane from low solute concentration to high solute concentration.
