Where does oxygenic photosynthesis occur?
Answers
Answer:
OXYGENIC PHOTOSYNTHESIS. In plants the photosynthetic process occurs inside chloroplasts, which are organelles found in certain cells.

Summary
The primary source of energy for nearly all life is the Sun. The energy in sunlight is introduced into the biosphere by a process known as photosynthesis, which occurs in plants, algae and some types of bacteria. Photosynthesis can be defined as the physico-chemical process by which photosynthetic organisms use light energy to drive the synthesis of organic compounds. The photosynthetic process depends on a set of complex protein molecules that are located in and around a highly organized membrane. Through a series of energy transducing reactions, the photosynthetic machinery transforms light energy into a stable form that can last for hundreds of millions of years. This introductory chapter focuses on the structure of the photosynthetic machinery and the reactions essential for transforming light energy into chemical energy.
Definition
Oxygenic photosynthesis is a non-cyclic photosynthetic electron chain where the initial electron donor is water and, as a consequence, molecular oxygen is liberated as a byproduct. The use of water as an electron donor requires a photosynthetic apparatus with two reaction centers. It is present in cyanobacteria and its evolutionary related eukaryotic organelles, the chloroplast. Oxygenic photosynthesis was responsible for the transformation of the Earth’s primitive anoxygenic atmosphere to one with molecular oxygen.
