Introduction
Photosynthesis is the process of plants converting light energy making chemical energy and storing it in the bonds of sugar.

Chlorophyll a and chlorophyll b are produced in  and are the pigments of photosynthesis.

Keep your head up! So you didn't do as well as you had hoped. You can take this opportunity to continue your study of . To increase your knowledge of this subject, study up on , , and . Once you understand the photosynthesis process, look into the related process of , which explains how organisms use the oxygen produced in photosynthesis.

Algae are capable of photosynthetic generation of energy. There are many different groups of photosynthetic algae. Like higher plants, they all have chlorophyll-a as a photosynthetic pigment, two photosystems (PS-I and PS-II), and the same overall chemical reactions for photosynthesis. Algae differ from higher plants in having different complements of additional chlorophylls. and have chlorophyll-a and chlorophyll-b. , , and have chlorophyll-a and chlorophyll-c. have chlorophyll-a and chlorophyll-d. The different chlorophylls and other photosynthetic pigments allow algae to utilize different regions of the solar spectrum to drive photosynthesis.

The final photosynthetic bacteria are in the genus . Halobacteria thrive in very salty environments, such as the Dead Sea and the Great Salt Lake. Halobacteria are unique in that they perform photosynthesis without chlorophyll. Instead, their photosynthetic pigments are bacteriorhodopsin and halorhodopsin. These pigments are similar to sensory rhodopsin, the pigment used by humans andother animals for vision. Bacteriorhodopsin and halorhodopsin are embedded in the cell membranes of halobacteria and each pigment consists of retinal, a vitamin-A derivative, bound to a protein. Irradiation of these pigments causes a structural change in their retinal. This is referred to as photoisomerization. Retinal photoisomerization leads to the synthesis of ATP. Halobacteria have two additional rhodopsins, sensory rhodopsin-I and sensory rhodopsin-II. These compounds regulate phototaxis, the directional movement in response to light.

Photosynthesis - LabLearner - The Science of Learning

Experiments are centered on the investigation of two areas pertaining to photosynthesis: factors that affect the photosynthetic process; and cellular structures or substances involved in photosynthesis.

Through experiments, students determine that carbon dioxide, light, and chlorophyll are three of the necessary components of photosynthesis. They also discover that during photosynthesis, plants produce oxygen and produce sugar, which is then quickly converted to starch.
