Why specialised transport systems are needed

Why specialised transport systems are needed

Larger organisms cannot rely on diffusion alone because, as size increases, surface area to volume ratio falls and many cells are far from the body surface. Oxygen and nutrients would arrive too slowly, and wastes would be removed too slowly, for a high metabolic rate.

Step-by-step lessons covering Eduqas A Level Biology Adaptations for transport for A Level Biology. Each lesson works through exam-style questions in Component 1, Component 2 and Component 3 format. 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.
