GCSE Biology - Photosynthesis #48

The video explains photosynthesis, a process occurring in plant leaves where chlorophyll absorbs light energy to convert carbon dioxide and water into glucose and oxygen. The chemical equation is detailed, highlighting its endothermic nature. The video recaps how plants obtain reactants and emphasizes glucose's importance, outlining its five main uses: respiration, cellulose, starch, amino acids, and oils. Finally, it introduces factors affecting photosynthesis rates, such as light intensity, temperature, carbon dioxide concentration, and chlorophyll amount.
