How is light used in photosynthesis

Webshone light from a lamp with a red light bulb onto the pondweed counted the bubbles of gas produced by the pondweed every minute for three minutes. The pupils repeated their experiment using a blue light bulb, a green light bulb and a yellow light bulb. A control is used in order to make the investigation fair. Web10 jul. 2024 · Principle of Oxygen Release in Photosynthesis. During oxygenic photosynthesis, light energy transfers electrons from water (H 2 O) to carbon dioxide (CO 2), to produce carbohydrates.In this transfer, the CO 2 is “reduced,” or receives electrons, and the water becomes “oxidized,” or loses electrons. Ultimately, oxygen is produced …
