What are the 4 types of photosynthesis?
What are the 4 types of photosynthesis?
The three main types of photosynthesis are C3, C4, and CAM (crassulacean acid metabolism). In college I had to memorize some of their pathways and mechanisms, but I will highlight what gives one an advantage over another and what types of crops, forages, and weeds have specialized C3 and C4 photosynthesis.
What is photosystem 1 and 2 in photosynthesis?
Photosystem I and photosystem II are the two multi-protein complexes that contain the pigments necessary to harvest photons and use light energy to catalyse the primary photosynthetic endergonic reactions producing high energy compounds.
What is the process of oxygenic photosynthesis?
During oxygenic photosynthesis, light energy transfers electrons from water (H2O) taken up by plant roots to CO2 to produce carbohydrates. In this transfer, the CO2 is “reduced,” or receives electrons, and the water is “oxidized,” or loses electrons. Oxygen is produced along with carbohydrates.
What is photosynthesis 4th grade?
Photosynthesisis a process by which plants make their own food in their leaves and give off oxygen and water that they are not using.
What is photosynthesis 7th class?
The process of making food by green plants in the presence of sunlight and chlorophyll is known as photosynthesis. Photosynthesis is the combination of two words- Photo + Synthesis. ‘Photo’ means light and ‘Synthesis’ means to make.
What is C3 C4 and CAM plants?
C3, C4 and CAM are the three different processes that plants use to fix carbon during the process of photosynthesis. Fixing carbon is the way plants remove the carbon from atmospheric carbon dioxide and turn it into organic molecules like carbohydrates.
What is difference between photosystem 1 and photosystem 2?
The main difference between photosystem 1 and 2 is that PS I absorbs longer wavelengths of light (>680 nm) whereas PS II absorbs shorter wavelengths of light (<680 nm).
What is difference between ps1 and ps2?
The key difference between both the photosystems – Photosystem I and photosystem II is that PS I tends to absorb light of longer wavelengths > 680nm, whereas PS II absorbs light of shorter wavelengths <680 nm.
What is oxygenic photosynthesis give one example?
In plants, algae and cyanobacteria, photosynthesis releases oxygen. This is called oxygenic photosynthesis. Although there are some differences between oxygenic photosynthesis in plants, algae, and cyanobacteria, the overall process is quite similar in these organisms.
Why is it called oxygenic photosynthesis?
The form of photosynthesis that first comes to mind when the term is mentioned is that carried out by the plants we see around us. It is called oxygenic photosynthesis because one of its products is molecular oxygen, resulting from the oxidation of water [5].
