About Eduqas A Level Biology 1.2 Cell Structure and Organisation

This topic covers cell ultrastructure and how cells are organised into tissues and organs. Expect microscope calculations and organelle function questions.

What you need to know

  • Eukaryotic organelles Nucleus, RER, SER, Golgi, mitochondria, chloroplasts, lysosomes, ribosomes and centrioles, each with a specific function.
  • Prokaryotic cells No nucleus, circular DNA, plasmids, 70S ribosomes and a peptidoglycan cell wall.
  • Viruses Non-cellular, with nucleic acid inside a protein capsid.
  • Organisation Cells, tissues, organs and organ systems.

Common mistakes in 1.2 Cell Structure and Organisation

  • Saying prokaryotes contain no DNA.
  • Confusing magnification and resolution.
  • Giving the wrong units in size calculations.

Try three 1.2 Cell Structure and Organisation exam-style questions

1. State the function of the rough endoplasmic reticulum. (1 mark)

Show the mark scheme answer

Synthesis and transport of proteins.

2. An image is 25 mm and the magnification is x5000. Calculate the actual size in µm. (2 marks)

Show the mark scheme answer

25 / 5000 = 0.005 mm (1) = 5 µm (1).

3. Give two structural differences between prokaryotic and eukaryotic cells. (2 marks)

Show the mark scheme answer

Any two: no nucleus, no membrane-bound organelles, smaller ribosomes, circular DNA (1 each).

1.2 Cell Structure and Organisation FAQs

What does Cell Structure and Organisation cover?

Eukaryotic and prokaryotic cell structure, viruses and levels of organisation.

Do I need magnification calculations?

Yes. Actual size = image size / magnification, with unit conversions.

Which practical links here?

Using a light microscope and making drawings, with a graticule to measure cells.
