Cell structure
18 review questions with answers for Cell structure. Read them here, or play the set as a class game on the projector. Free to host, and students join with a code.
Organelle where most aerobic respiration takes place?
- Ribosome
- MitochondrionRight answer
- Nucleus
- Chloroplast
What this set covers
Organelles and cell types are the focus here: mitochondrion, ribosome, nucleus, chloroplast, vacuole, cell wall and membrane, plus prokaryotic features such as plasmids and flagella, and specialized cells like root hair and palisade cells.
- Common mix-up
- Students often mix up the cell membrane and the cell wall: the membrane is partially permeable and controls entry, while the wall is a rigid outer layer of cellulose in plants or chitin in fungi.
- Review tip
- Sketch one plant cell and one bacterium side by side, label every structure from memory, then circle the parts the bacterium lacks.

Play it as a class game
Play this set opens it in splycr, where you can host it for your class straight away. Hosting needs no account: put the room code on the projector, and students join from a phone with the code and their first name. Each question plays as multiple choice, and the three wrong options were written for that question.
