IGCSE Bio Topic 6 – Plant Nutrition

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.

Topic 6 revision notes in downloadable word format.

6.1 PHOTOSYNTHESIS

The simple story of photosynthesis and food from TED-Ed (4m 1s).

7.1 Diet

Nice concept map to help revise this section:

The six major nutrients (you also need fibre):

Science Bank 21 (Food & Digestion): part 1 – Food Tests; part 2 – the Digestive System (from 4m 40s); part 3- Digestive Enzymes (from 9m):

7.1 Diet revision notes in downloadable word format.

Bitesize Top 20 Demos – Food as a Fuel (2m 16s).

A lesson in Nutrition. Vitamins, minerals, balanced diet from Ms Cooper (14m 19s) and in Nutrition, Carbohydrates, proteins and lipids (20m 50s).

Here’s a useful powerpoint, although it doesn’t cover everything we need to know:
