B4.2 Plant Nutrition (Combined Science)

For self-assessment questions, with exercises and discussions, just click on the correct topic at Biology GCSE & IGCSE Question Bank. Powerpoints can be downloaded from the same site here. The s-cool revision site lets you revise the topic, summarizes the topic & tests you on it. Skoool gives you a lesson, including progress questions, for each Biology topic but you’ll need sound on for it. GCSE Bitesize has revision pages (that take you through the topic), a test and an activity.

Here are the key terms and some definitions: Key Terms B4.2

Many assessment statements are also covered by Stephanie Castle (with more being added all the time).

A lovely site about polymers that includes starch and cellulose (with a nice animation), and hers’s a short, simple animation to show glucose in water. Finally, here is an excellent lesson from TED-Ed on what is fat? – in a bit more detail than we need.
