AS Biology - Cells (eukaryote and prokaryote), Viruses, and Microscopy

This comprehensive set of instructional slides covers the fundamental principles of cell biology and virology. The resource transitions from basic cellular classification to the detailed structural analysis of pathogens and organelles.

Embedded past exam questions and answers from Edexcel B. However, the slides can be used for any specification.

Core Content Areas:

• Cell Classification: Eukaryote cell structure including all major organelles. Detailed comparison between Eukaryotes and Prokaryotes, including the specific composition of the peptidoglycan cell wall in bacterial cells.
• Organelle Analysis: A comparative study of mitochondria and chloroplasts, focusing on structural similarities and functional differences.

**Virology: **
An overview of virus structure and classification. Includes specific case studies required for Edexcel, on:

• Tobacco Mosaic Virus (TMV)
• Lambda Phage
• HIV
• Ebola

**Microscopy and Quantitative Skills: **
An introduction to microscopy techniques and a step-by-step guide on how to calculate actual cell size and magnification using the magnification formula.

**Diagram-Led: **
Includes clear structural diagrams of viruses and cell types to support visual learners.

**Skill-Based: **
Includes practice opportunities for magnification calculations.
