a by-product. This process is called photosynthesis. Temperature‚ carbon dioxide concentration and light intensity are factors that can limit the rate of photosynthesis. Plants also need mineral ions‚ including nitrate and magnesium‚ for healthy growth. They suffer from poor growth in conditions where mineral ions are deficient. Photosynthesis Photosynthesis is the chemical change which happens in the leaves of green plants. It is the first step towards making food - not just for plants but ultimately
