Build Your Membrane Transport Map
Turn your biology notes into a branching map of every transport process you need to know.
Map from your own notes
Upload a PDF, Word file or slides from class, and the AI extracts the transport processes automatically.
Passive versus active branches
Separate processes that need energy from those that follow the concentration gradient, so the differences stay clear.

Concept Map of Movement Across Membranes
A concept map of movement across membranes shows how substances cross the cell's phospholipid bilayer. The topic divides into passive transport, which needs no energy and follows the concentration gradient, and active transport, which needs energy, usually from ATP, to move substances against it. Passive transport includes simple diffusion, facilitated diffusion through channel and carrier proteins, and osmosis, the diffusion of water.
- Passive transport: movement down a concentration gradient, no energy needed
- Simple diffusion: small or nonpolar molecules pass directly through the bilayer
- Facilitated diffusion: channel and carrier proteins help specific molecules cross
- Osmosis: net movement of water across a selectively permeable membrane
- Active transport: movement against a gradient using ATP and pumps such as Na+/K+
Use the map to revise for exams, compare the two main categories, and check your understanding of each process. You can create a personalized version from your own notes with CogniGuide.

Membrane Transport Questions
Answers on the main transport processes and on building your own map.
What is the difference between diffusion and osmosis?
Diffusion is the movement of any particle from high to low concentration. Osmosis is the diffusion of water across a selectively permeable membrane, from a region of lower solute concentration to higher solute concentration.
Why does active transport need energy?
Active transport moves substances against their concentration gradient, which is uphill movement. Cells supply this energy mainly by hydrolysing ATP to power pumps such as the sodium-potassium pump.
Which file types can I use to build the map?
You can upload PDF, Word (DOCX), PowerPoint (PPTX), text or Markdown files, or images of your notes. You can also type the topic directly and the AI will build the map from it.
Is it free to make a transport map with CogniGuide?
Yes, the free plan includes 5 creations a week and needs no payment. Paid plans raise these limits. Each map can also be turned into a quiz to test your knowledge.
