A2.2 Cell Structure - Full Lesson

This complete IBDP Biology lesson pack supports teaching of A2.2 Cell Structure, helping students understand cells as the basic unit of life and develop key microscopy skills.

The resources cover cell theory, structures common to all cells, prokaryotic and eukaryotic cell structure, microscopy, micrographs, endosymbiosis, cell differentiation and the evolution of multicellularity. The pack also includes a practical-style microscopy activity using an interactive simulator, allowing students to practise calibration, measurement and biological calculations.
Designed for IBDP Biology teachers, this resource provides structured lesson materials, student notes, presentation notes and activities to support both classroom teaching and independent study.
