1. 1.1 Use a light microscope
How do we view cells

2. Essential idea
The evolution of multicellular organisms allowed cell specialisation and cell replacement

3. Understandings, skills, applications
Use a light microscope to investigate the structures of cells and tissues, with drawings of cells.
Calculate the magnification of drawings and the actual size of structures and ultrastructures shown in drawings and micrographs.

4. Internal assessment
Mandatory lab (assessed???)

5. Cellular hierarchy Cells – smallest unit of life
Tissues – group of cells
Organs – groups of tissues
Systems – groups of organs
Organisms – groups of systems

6. Mandatory Practicals 6+1 (Paper 3)
P1 1.1 Calculation of magnification of drawings, actual size of structures from drawings or micrographs
