Eukaryotic cells contain a membrane bound nucleus; this contains the DNA.

Organisms that are made up of more than one cell are multicellular.

Prokaryotic cells have no membrane bound nucleus; DNA is free floating in the cytoplasm.

An organism that consists of only one cell is unicellular.

Combined science

Cells

Light microscopy: observing and drawing cells

Animal cells: common structures and specialised cells

Plant cells: common structures and specialised cells

Common structures of prokaryotic cells

The size and scale of cells: the basics

Pupils will learn about biological molecules that are essential to life, including sugars and other carbohydrates, proteins and lipids, and the role of enzymes in catalysing the chemical reactions in which these substances are used and made.

Pupils learned that photosynthesis in producers makes glucose, a type of carbohydrate, which is used to make biomass and as a fuel for cellular respiration.

This unit covers the structure and function of sub-cellular components in eukaryotic and prokaryotic cells and explores DNA as the genetic material of organisms. It explains genetic terms, protein synthesis, and how genetic variants influence phenotypes.
