Cell division
20 review questions with answers for Cell division. Read them here, or play the set as a class game on the projector. Free to host, and students join with a code.
Division that produces two genetically identical diploid cells for growth and repair?
- Meiosis
- MitosisRight answer
- Fertilisation
- Differentiation
What this set covers
From mitosis and meiosis to cancer and stem cells, this set follows the cell cycle: interphase, metaphase, anaphase, cytokinesis, sister chromatids, benign and malignant tumors, differentiation, meristems and therapeutic cloning.
- Common mix-up
- Students often mix up mitosis and meiosis: mitosis gives two identical diploid cells for growth and repair, while meiosis gives four different haploid gametes, with 46 versus 23 chromosomes in humans.
- Review tip
- Write the stages of mitosis in order, add a one-line description of what the chromosomes are doing at each, then cover the list and rebuild it.

Answer: Therapeutic cloning
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.
