Detailed explanation-1: -chloroplast, structure within the cells of plants and green algae that is the site of photosynthesis, the process by which light energy is converted to chemical energy, resulting in the production of oxygen and energy-rich organic compounds.

Detailed explanation-2: -In the process of photosynthesis, plants create sugars and release oxygen (O2). The oxygen released by the chloroplasts is the same oxygen you breathe every day. Chloroplasts are found in plant cells, but not in animal cells.

Detailed explanation-3: -Scientists estimate that roughly half of the oxygen production on Earth comes from the ocean. The majority of this production is from oceanic plankton-drifting plants, algae, and some bacteria that can photosynthesize. One particular species, Prochlorococcus, is the smallest photosynthetic organism on Earth.

Detailed explanation-4: -Carbon dioxide and water go through a series of chemical reactions in the chloroplasts of plants to produce glucose with oxygen as a byproduct. In the leaf of the plant, there are several different tissues. The upper and lower most tissues are composed of small, boxed-shaped cells known as the epidermis.

Detailed explanation-5: -Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP. This process releases carbon dioxide and water as waste products.
