Cell Division and the Cell Cycle

What the resources cover

The page follows the cell cycle from interphase to division. The mind map Mitosis starts with chromatin, histones and chromosomes, and explains how DNA is replicated and wound up before a cell divides. A-Level Biology: Cell Division places mitosis and meiosis in eukaryotic cells and gives examples such as the lining of the small intestine, which is replaced, and liver cells, which divide only rarely.

Where to start

Begin with a mind map to see the whole sequence. Then read a short set of notes, such as the ones titled The Cell Cycle, to fill in the detail. Flashcards help with the stage order and key words: the deck on the process of cell division for Honors Biology Chapter 10 covers G1, S, G2, prophase, metaphase, anaphase, telophase and cytokinesis.

Using quizzes and maps together

Use a quiz after each map, not before. The Cell Cycle/Mitosis/Meiosis Practice Exam asks about G2 phase and the plane where chromosomes line up at metaphase. The IB Bio - Mitosis Quiz checks interphase and what stays the same after mitosis. Note which questions you miss, go back to the matching map branch, then try again.

• Mitosis: growth and repair, with identical daughter cells.
• Meiosis: the Meiosis mind map covers prophase I and metaphase I, where homologous pairs line up.
• Chromosome counts: the Meiosis, Karyotypes, and Reproduction Practice Test has counting questions.

Control and cancer

The CANCER mind map links mutations in genes that aid cell division, such as proto-oncogenes, to uncontrolled growth. The Cell division and cancer quiz is a good follow-up once the basics feel secure.

Where this fits

This unit sits in the Molecules and Cells strand of Biology and natural sciences. Resources mention exams including GCSE Biology, A-level Biology, IB Biology, AP Biology and MCAT, so pick the ones that match your course. Choose one mind map and one quiz today, and see how far they take you.
