H2o and sunlight and the major sources required
Photosynthesis in plants occurs in two stages.
In the photosynthesis takes place in a chloroplast of a thin-walled mesophyll cell and a 4-carbon acid is handed off to a thick-walled bundle sheath cell where the Calvin cycle occurs in a chloroplast of that second cell. This protects the Calvin cycle from the effects of .

Carbon dioxide is captured in a cycle of reactions known as the Calvin cycle or the Calvin-Benson cycle after its discoverers. It is also known as just the C3 cycle. Those plants that utilize just the Calvin cycle for carbon fixation are known as . Carbon dioxide diffuses into the stroma of chloroplasts and combines with a five-carbon sugar, ribulose1,5-biphosphate (). The enzyme that catalyzes this reaction is referred to as , a large molecule that may be the most abundant organic molecule on the Earth. This catalyzed reaction produces a 6-carbon intermediate which decays almost immediately to form two molecules of the 3-carbon compound 3-phosphoglyceric acid (). The fact that this 3-carbon molecule is the first stable product of photosynthesis leads to the practice of calling this cycle the C3 cycle.

Algae are a very diverse group of predominantly aquatic photosynthetic organisms that account for almost 50% of the photosynthesis that takes place on Earth. Algae have a wide range of antenna pigments to harvest light energy for photosynthesis giving different types of algae their characteristic colour. Early work done with algae contributed much to what is presently known about the carbon dioxide fixation pathway and the light harvesting reactions. The processes of photosynthesis in algae and higher plants are very similar. From among the three types of carbon dioxide‐concentrating mechanisms known in photosynthetic organisms, two types are found in different types of algae. Algae are proposed to play a role in the global carbon cycle by helping remove excess carbon dioxide from the environment. Recently, algae are recognized as a promising biodiesel source due to its efficient absorption and conversion of solar energy into chemical energy.

Photosynthesis is a process through which plants produce their food. In this process, plants absorb water from the soil through roots and carbon dioxide gas from the air through leaves and combine both of them to build glucose. There are many factors which are necessary for photosynthesis. These factors are light, chlorophyll, carbon dioxide, water, and temperature.
