Ultrastructure, micrographs and scale
Ultrastructure means the fine internal detail of cells and organelles that is too small to resolve clearly with a light microscope. A micrograph is an image produced by a microscope. To study ultrastructure, biologists usually use electron microscopes.
Step-by-step lessons on Edexcel A A Level Biology Eukaryotic and prokaryotic cell ultrastructure. Each one builds up to exam-style questions. Build a strong foundation in cell biology and biochemistry early on, since later topics on genetics, ecology and physiology all draw on these core concepts.
