WEBMar 1, 2024 · In chemical terms, photosynthesis is a light-energized oxidation–reduction process. (Oxidation refers to the removal of electrons from a molecule; reduction refers to the gain of electrons by a molecule.) In plant photosynthesis, the energy of light is used to drive the oxidation of water (H 2 O), producing oxygen gas (O 2 ), hydrogen ions (H ...

WEBPhotosynthesis ( / ˌfoʊtəˈsɪnθəsɪs / FOH-tə-SINTH-ə-sis) [1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their activities.

WEBJul 17, 2016 · The ecological importance of photosynthesis. Photosynthetic organisms, including plants, algae, and some bacteria, play a key ecological role. They introduce chemical energy and fixed carbon into ecosystems by using light to synthesize sugars. Since these organisms produce their own food—that is, fix their own carbon—using light …

WEBMar 20, 2024 · Photosynthesis (Google doc) Most life on Earth depends on photosynthesis .The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O 2) and chemical energy stored in glucose (a sugar). Herbivores then obtain this energy by eating plants, and carnivores …

WEBPhotorespiration: C3, C4, and CAM plants. The Calvin cycle enzyme rubisco is essential...but it also has a bad habit. Rubisco sometimes acts on oxygen rather than carbon dioxide, leading to a carbon-wasting side process called photorespiration. Learn about the strategies C4 and CAM plants use to minimize photorespiration.

WEBThe whole process of photosynthesis is a transfer of energy from the Sun to a plant. In each sugar molecule created, there is a little bit of the energy from the Sun, which the plant can either use or store for later. Imagine a pea plant. If that pea plant is forming new pods, it requires a large amount of sugar energy to grow larger.
