Investigate biological material at the microscopic level

What this standard covers

• Preparing biological material for viewing under a light microscope — tears, sections, impressions, cavity slides and stains
• Viewing two different plant tissues and one unicellular organism, and working out the magnification
• Recording what you see in biological drawings that follow the accepted conventions
• Identifying specialised features: cell shape, the arrangement of cells, and which organelles are present and how many
• Relating each feature to the function of the cell or tissue, and giving the reason it does that job well
