AP Biology Unit 2: Cell Structure and Function
3 ready-made review sets for this unit, 43 questions in all, to play as a class game on the projector. Free to host, and students join with a code.

- Rough ER
- Golgi ApparatusRight answer
- Mitochondria
What Unit 2 covers
Unit 2 moves from molecules to the cell: what each organelle does and how the endomembrane system works as one (rough ER to Golgi to vesicle), why cells stay small (the surface area to volume ratio), and the fluid mosaic membrane, with what crosses it by diffusion, facilitated diffusion and active transport, and what goes in and out by endocytosis and exocytosis. It ends with tonicity, water potential, compartmentalization and the endosymbiotic origin of mitochondria and chloroplasts.
Where students slip
- Hypertonic and hypotonic compare one solution with another. Students attach the word to the wrong side, and then send the water the wrong way.
- As a cell grows, its volume grows faster than its surface area, so the surface area to volume ratio falls.
- Water moves from higher to lower water potential, and adding solute lowers water potential.
- Prokaryotes do have ribosomes. What they lack is a nucleus and other membrane-bound organelles.
The sets
Play this set opens the set in splycr, where you can read every question and host it for your class straight away. Hosting needs no account, and students join with the code on the board. A free account lets you copy a set and edit it.
The questions come from the Biology by Bradford flashcard bank, written by an IB and AP Biology teacher. Each one plays as multiple choice, and the wrong options are other answers from the same set.
As a cell grows larger, which increases faster: volume or surface area?
Answer: Volume
Molecule that helps regulate membrane fluidity at different temperatures?
Answer: Cholesterol
Diffusion of polar or charged molecules through a transport protein?
Answer: Facilitated Diffusion
Specialized channel protein used specifically for rapid water transport?
Answer: Aquaporin
Shrinking of a plant cell's cytoplasm and membrane away from the wall in a hypertonic solution?
Answer: Plasmolysis
A protein is found in the plasma membrane. Where was it originally synthesized?
Answer: Rough ER
Game modes that suit this unit
Every set plays in all eight modes. These two fit this unit best.
Racer in teams
In team Racer each teammate sees different options and only one has the right answer, so the team has to talk. Organelles and transport suit this: someone has to explain why it is the rough ER and not the Golgi before anyone taps.
Kaboom
The answers in these sets are short (an organelle, a kind of transport, a word like hypotonic), so the bomb moves fast and every student answers many times. Nobody is knocked out: the holder just loses points when it goes off.
