A type of reproduction that combines the genetic material of two organisms to produce genetically different offspring.

An organism's sex cells that contain half the number of chromosomes.

A type of cell division that forms the gametes.

Highly coiled strands of DNA found inside the nucleus of eukaryotic cells.

A cell with half the number of chromosomes.

Making gametes: meiosis

Combined science

Growth in multicellular organisms

The cell cycle and cell division: mitosis

Observing mitosis in plant cells using a light microscope

The structure of DNA: including nucleotides

Errors in cell division and cancer: beyond the basics

Pupils will learn about unspecialised cells in animals and plants, how they become specialised, and potential benefits and issues with using stem cells in medicine. 

Pupils learned about dominant and recessive alleles, and how to use models of single gene inheritance to make predictions about the genotypes and phenotypes of offspring.

This unit covers mitosis and the cell cycle in growth, cancer as uncontrolled cell division, and the role of mutations in genetic variation. It explains meiosis in gamete formation and chromosome reduction. The emphasis is on recording observations and interpreting patterns to draw conclusions.

Cell division: mitosis and meiosis

What word is used to describe the sex cells?

where the sperm and egg fuse to form the zygote

involves two parents producing genetically different offspring

Match each process to the correct description. 

The chromosomes line up and DNA is mixed.

Put the stages of meiosis into the correct order. 

What word is used to describe cells with half the number of chromosomes?

Which of the following are true for mitosis?

Reproduction that involves two organisms is called ...

What is the name of the process where the sperm and the egg fuse together?

What is the name of the cell that is produced by the fusing of the sperm and the egg during fertilisation?

chromosomes line up along the middle of the cell

chromosomes are pulled to either end of the cell

Put these stages of the cell cycle and cell division in order. 

Gametes are the name given to sex cells; what are the sex cells in humans?
