What’s on the The Cell Membrane poster
A 6-row table: Mechanism · Needs ATP? · Moves.
Transport across the membrane, by mechanism.
- Simple diffusion — No — Small, non-polar: O₂, CO₂
- Facilitated diffusion — No — Via channel or carrier proteins
- Osmosis — No — Water, down its potential gradient
- Active transport — Yes — Against the gradient, via a pump
- Endocytosis — Yes — Bulk material in
- Exocytosis — Yes — Bulk material out
The sodium-potassium pump moves 3 Na⁺ out and 2 K⁺ in per ATP, and consumes a large share of a cell's energy budget.

- Who is the The Cell Membrane (Cell biology) poster for?
- The Cell Membrane (Cell biology) belongs to the Biology section rather than to a school year, because life science is not something one grade owns. Anyone learning cell biology can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the The Cell Membrane (Cell biology) poster?
- A phospholipid bilayer with proteins floating in it. Selectively permeable by design. A wall chart earns its place by being glanceable from where the work is happening, so The Cell Membrane (Cell biology) belongs on the wall where that life science work actually happens, within glancing distance, rather than filed away.
- What other posters go with The Cell Membrane (Cell biology)?
- Cell Cycle Control, Differentiation and Cell Signalling sit alongside The Cell Membrane (Cell biology) in the Biology section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Cell Cycle ControlDifferentiationCell Signalling
- Is the The Cell Membrane (Cell biology) poster free to download and print?
- Yes. The Cell Membrane (Cell biology) downloads as a free PDF with no account, no email and no watermark, like everything else in the Biology section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the The Cell Membrane (Cell biology) poster print at?
- The Cell Membrane (Cell biology) is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of The Cell Membrane (Cell biology) loses nothing.Printing guide
