The chloroplast contains chlorophyll<span> within its thylakoids, which absorbs light energy and gives chloroplasts its green color. Stacks of thylakoids are known as grana, which exist in the open space of the chloroplast known as the stroma.</span>
Oxygen would slowly deplete into carbon dioxide as there is no photosynthesis to create more. Earth would not be able to support human life later on.
Carbon fixation is the process in which plants remove the carbon from atmospheric carbon dioxide and turn it into organic molecules like carbohydrates.
Because different type of plants are located in regions with different conditions they are different types of carbon fixation. Plants that live in arid regions need to conserve water, while plants that live in more moist conditions will not need to conserve water.
The carbon fixation in C3 plants is one-step process. An oxidation reaction occurs because of the enzyme RuBisCo. During the oxidation some of the energy used in photosynthesis is lost in a process known as photorespiration.
