Module 2.1.1: Cell structure (OCR A-level Biology A)

As cells are the building blocks of living organisms, and Biology is the study of life, it’s fairly obvious that a clear understanding of cell structure is going to be critical for the success of an A-level student on the OCR A-level Biology A course. The 6 lessons included in this bundle are highly detailed and have been intricately planned to contain the detail needed at this level and to make links to topics in the other modules of the specification.

The lesson PowerPoints and accompanying resources contain a wide range of tasks which will engage and motivate the students whilst covering the following specification points in module 2.1.1:

• The use of microscopy to observe and investigate different types of cell and cell structure in a range of eukaryotic organisms
• The use of the eyepiece graticule and stage micrometer
• The use of staining in light microscopy
• The use and manipulation of the magnification formula
• The difference between resolution and magnification
• The ultrastructure of eukaryotic cells and the functions of the different cellular components
• The interrelationship between the organelles involved in the production and secretion of proteins
• The importance of the cytoskeleton
• The similarities and differences in the structure and ultrastructure of prokaryotic and eukaryotic cells
