Introduction Photosynthesis is the most important set of chemical reactions in the world. Yes, it is. The result of photosynthesis is a metabolic product called oxygen which is the basis of aerobic metabolism. In addition, plants that use photosynthesis also the mainstay of all civilizations. Indigenous people in Peru, grew potatoes, in Mexico it was corn, in the Middle East (Iran and Iraq) it was wheat, in China it was rice. The biological importance of photosynthesis cannot be overestimated nor can its current financial clout. Huge multinational industries are designed around producing the staples (flour, rice, beans, and potatoes) to support the world. The term “photosynthesis” is somewhat misleading. Literally, it means “making light” which plants do not do. Photosynthesis is a set of chemical reactions occurring in plants to produce energy for the plant in the form of ATP which is used to power all the anabolic activities of the plant cell. What is most remarkable about this process is that the plant cell is able to grow needing only carbon dioxide, water and sun light. It is the ultimate solar gathering system. The ability to take certain wavelengths of sunlight to be subsequently used to produce all the chemical needs of a weed to a tree is remarkable. Photosynthesis

The plant cell is the functional unit of plants. It differs from animal cells in that it has a cell wall in addition to a plasma membrane. It serves a variety of functions from protecting the cell to regulating the life cycle of the plant. In addition, plants have Chloroplasts which are the structure that converts light energy to electrical energy. Interestingly, the plant cell also has mitochondria which produce energy when light is not available for the Chloroplasts. Each plant cell has a large single vacuole that stores compounds, helps in plant growth and plays an important structural role. Notice that all the cellular machinery that was noted in the animal cells to make proteins is also in the plant cell. The nucleus, nucleolus, nuclear envelope, rough endoplasmic reticulum, Golgi bodies and ribosomes are all present. The working part of the plant cell are the Chloroplasts which are All of the green structures in plants, including stems and unripened fruit, contain Chloroplasts, but the majority of photosynthesis activity in most plants occurs in the leaves. On the average, the chloroplast density on the surface of a leaf is about one-half million per square millimeter. The chloroplast, basically, is the organelle responsible for photosynthesis.
