Think plants are defenceless? Think again! This article looks at some of the hidden plant defences against both pests and dieseases, and how plants can switch on defence-related genes. If you're thinking about studying biology at University, this will challenge and extend your knowledge so far.

Think you know how plants 'see' light? Think again. This article investigates how light influences the activity of thousands of plant genes. If you're thinking about studying biology at University, this will challenge and extend your knowledge so far.

The article examines the complex history of the genetics of chloroplasts, linking it to our understanding of genetics as a whole. If you're thinking about studying biology at University, this will challenge and extend your knowledge so far.

In your science experiments, often you need to know how much material to use or how much of a solute is present in a solution. Almost certainly you will need to do some calculations! This survival guide should help you to do these calculations.

Modelling is key to today's biological research, with computer modelling is set to become one of the main methods biologists use to explain their theories and make predictions. This collection of resources introduces the importance of biological modelling for A-level students and their teachers.
