Digital file- Question & Answer sheet - AQA GCSE Combined Science-Mitosis & the Cell cycle

These question and answer sheets cover AQA GCSE Combined Science: Trilogy 8464 – 4.1.2.2 Mitosis and the Cell Cycle:

• Cells divide in a series of stages called the cell cycle.

• During the cell cycle, genetic material is doubled and then divided into two identical cells.

• Before a cell divides, it grows and increases the number of sub-cellular structures such as ribosomes and mitochondria.

• The DNA replicates, forming two copies of each chromosome.

• During mitosis, one set of chromosomes is pulled to each end of the cell and the nucleus divides.

• Finally, the cytoplasm and cell membranes divide to form two identical cells.

• Students should understand the three overall stages of the cell cycle but do not need to know the phases within mitosis.

• Mitosis is important for the growth and development of multicellular organisms.

• Be able to recognise and describe situations where mitosis is occurring in context.

Even if you’re studying a different exam board, these cards are a useful way to review core biology concepts such as cell division and growth. Check your own syllabus to focus on exactly what you need.
