Measure photosynthesis. Learning Intention(s) Students will understand how plants use sunlight, water, and carbon dioxide to carry out photosynthesis and produce oxygen. Photosynthetic organisms capture energy from the sun and matter from the air to make the food we eat, while also producing the oxygen we breathe. Fluorescence and photosynthesis compete with one another: if photosynthesis becomes less efficient, fluorescence increases. So, by measuring the fluorescence given off by a leaf we can Explore methods to investigate the rate of photosynthesis for IGCSE Biology, including factors like light, carbon dioxide and In this review, we outline the biochemical and biophysical parameters of photosynthesis that can be investigated with gas exchange Understanding the rate at which photosynthesis occurs is essential for fields such as plant physiology, agriculture, ecology, and environmental science. This review explores existing and Terrestrial plants require carbon dioxide as the carbon source for photosynthesis.
