Plants are fascinating – and vital for life. Through photosynthesis they absorb carbon dioxide, and produce oxygen. One tree produces nearly 260 pounds of oxygen each year whereas an acre of trees can remove up to 2.6 tons of carbon dioxide each year. Trees also provide homes to thousands of different animals. One single tree in Peru supports 43 different species of ant. This is approximately the entire number of ant species in the British Isles.
GCSE scientists, you need to be able to describe how to investigate photosynthesis practically, so why not try Part 2 of our “How to work with Photosynthesis” revision guide. This guide follows on from Part 1, and covers how to complete practicals to measure the rate of photosynthesis. It explains what equipment is required, and which variables to control. Instructions on calculating the rate of photosynthesis using the inverse square law is also included.
