About cell division and the cell cycle notes
GoConqr OriginalUsing cell division and the cell cycle notes
The notes on this page cover stages of mitosis, the cell cycle, meiosis and chromosomes. The Cell Cycle describes growth and division, while Meiosis Producing Genetic Variation covers segregation, independent assortment and crossing over.
Start with The Cell Cycle if you want an overview before looking at individual stages. For a closer look at mitosis, the notes on cell division list the stages from interphase to cytokinesis. Mitosis and meiosis offers another place to explore the topics together.
Revise with notes and other formats
Read a section, then write a short summary of its stages or key terms. Return to the notes to check what you missed. When you want a different way to review, switch to flashcards on the unit page for terms, or try a quiz to check your understanding.

Frequently asked questions
Which notes should I start with?
Start with The Cell Cycle for an overview of growth and division. If you are focusing on mitosis, the notes on cell division list its stages. For meiosis and variation, Meiosis Producing Genetic Variation covers segregation, independent assortment and crossing over.
Are these notes free to use?
Yes. Every resource listed here is free to open and study, with no account needed. The notes were made by GoConqr users rather than GoConqr. A free account also lets you save quiz scores and make your own quizzes, mind maps, flashcards and notes.
Which levels and exams do the notes suit?
The collection includes material for school and university study. Resources mention exams such as GCSE Biology, A-level Biology, IB Biology and AP Biology. Look at the title and content of a set of notes to see whether its topics match what you are studying.
