After exploring this lesson, you'll be able to define and identify C4 plants. Learn about what a C4 plant is and what makes C4 plants unique. Then you can test your knowledge with a quiz.

Fig. 85 C3 and C4 plants . Starch formation in C4 plants. C3 plants and C4 plants a grouping of higher plants, related to the carbon content of the compound produced when carbon dioxide is fixed during PHOTOSYNTHESIS. In C3 plants (the most common type), carbon dioxide combines with 5-carbon ribulose diphosphate to produce two molecules of 3-carbon ...


What Is the Definition of a C4 Pathway? The C4 pathway is a method plants use to convert atmospheric carbon dioxide into a chemical compound containing four carbons. About.com explains that plans that utilize this pathway usually originate in subtropical areas.


C 4 carbon fixation or the Hatch–Slack pathway is a photosynthetic process in some plants. It is the first step in extracting carbon from carbon dioxide to be able to use it in sugar and other biomolecules. It is one of three known processes for carbon fixation."C 4" refers to the four-carbon molecule that is the first product of this type of carbon fixation.


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.


Science · Biology · Photosynthesis · Photorespiration: C3, C4, and CAM plants C3, C4, and CAM plants How the C4 and CAM pathways help minimize photorespiration.


A plant that more efficiently metabolizes necessary carbon through the use of a malate or oxaloacetate shuttle mechanism between mesophyll and bundle-sheath cells. Angiosperm species preferring dryer climates, such as maize, are typical members of the C4 pathway, tending to have Krantz anatomy as well.


In C4 plants, the C3 style cycle only occurs in the interior cells within the leaf; surrounding them are mesophyll cells which have a much more active enzyme, called phosphoenolpyruvate (PEP) carboxylase. Because of this, C4 plants are those that thrive on long growing seasons with lots of access to sunlight.


Well C4 plants get their name because in their cycle, a molecule made up of four carbon atoms is made but we won't go into too much into that process because our focus is on the C3 plant.
