Master Mitosis: A Crucial Process in Biology

Biology Quiz - Unit 2 - Mitosis (Questions)

This GCSE Biology quiz on mitosis tests how cells divide for growth and repair, following chromosomes as they line up, separate, and form two identical daughter cells.

Fascinating Fact:

Spindle fibres form and attach to the centromeres of each chromosome, helping to move chromatids during division.

In GCSE Biology, mitosis is the process that produces new body cells for growth and repair. You study how chromosomes are copied, arranged on the spindle, and separated into two identical nuclei.

Key Terms

Mitosis: Cell division that produces two genetically identical diploid cells for growth or repair.
Chromosome: A long, coiled DNA molecule carrying many genes, found in the nucleus of cells.
Spindle fibre: A protein fibre that attaches to chromosomes and helps separate chromatids during mitosis.

Frequently Asked Questions (Click to see answers)

What is mitosis in GCSE Biology?

In GCSE Biology, mitosis is a type of cell division that produces two identical daughter cells. It keeps the chromosome number the same and is used for growth and repair.

How is mitosis different from meiosis?

Mitosis makes two identical diploid cells, while meiosis makes four non identical haploid gametes. Meiosis leads to variation in offspring, but mitosis does not.

Why is mitosis important in the human body?

Mitosis is important because it replaces worn out or damaged cells and allows the body to grow. It also helps heal cuts by making new skin cells.
