Topic 2.1: Cell structure (AQA A-level Biology)

This bundle of 9 lesson PowerPoints and accompanying resources contain a wide variety of tasks which will engage and motivate the students whilst covering the details of topic 2.1 of the AQA A-level Biology specification. Cells and their structure are linked to all of the other 7 topics in this course so a clear understanding is critical to a student’s success.

The tasks which include exam-style questions (with displayed mark schemes), discussion points and quiz competitions will cover the following parts of topic 2.1:

• The structure and function of the cell-surface membrane, nucleus, nucleolus, mitochondria, chloroplasts, Golgi apparatus, lysosomes, ribosomes, RER and SER, cell wall and cell vacuole
• The specialised cells of complex, multicellular organisms
• The structures of a typical prokaryotic cell
• The differences between prokaryotic and eukaryotic cells
• The structure of viruses
• The principles and limitations of optical microscopes, transmission electron microscopes and scanning electron microscopes
• Measuring the size of an object using an optical microscope
• Using the magnification formula
• The principles of cell fractionation and ultracentrifugation
