Plants might seem passive, defenceless and almost helpless. But they are most definitely not! Thanks to a war with animals that's lasted over 300 million years, they've developed many terrifying and devious ways to defend themselves and attack their enemies. Vicious poisons, lethal materials and even cunning forms of communicating with unlikely allies are just some of the weapons in their armoury. Using these and other tactics, plants have seen off everything from dinosaurs to caterpillars.
In the 2009 Royal Institution Christmas Lectures, Prof Sue Hartley will show you plants as you've never seen them before. They are complicated, cunning, beautiful and with plenty of tricks up their sleeve. And what's more, we humans are dependent on them in ways you'd never imagine. As well as much of our food, our drugs, medicines and materials are all by-products of this epic 300 million year war.
In 2009, the lectures have moved to a new home on More4, starting on Monday 21 December and then every night that week at 7pm. You can access More4 on Freeview Channel 14, Freesat Channel 124, Sky Digital Channel 138 and Virgin Media Channel 145. You will also be able to watch them whenever you want on the Channel 4 on demand service, 4OD.
