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.

What is the process by which bacterial cells divide?

Short ring of DNA that can cause variation when transferred.

A type of cell with no nucleus, usually between 1-5 µm in length.

A type of cell with a nucleus, usually between 5-100 µm in length.

A membrane bound sub-cellular structure that usually contains DNA.

Match the term to its correct definition. 

During binary fission, the DNA splits in half.

Two genetically identical cells are produced during binary fission.

Prokaryotic cells are usually more complex than eukaryotic cells.

Prokaryotic cells usually contain a cell wall, cytoplasm and a cell membrane.

What is the name of the substance that carries the genetic information in cells?

Which sub-cellular structure is **not** present in this bacterial cell?

What is the correct symbol for micrometres?

The cell wall allows substances to enter and exit the cell.

The cell wall is where many chemical reactions take place.

The cell wall provides structure and gives the cell its shape.

The cell wall controls the activities of the cell.

What is the function of the cell wall in many cells?
