GENERAL HISTOLOGY

Detailed explanation-1: -Photosynthesis is a process by which green plants prepare their own food from carbon dioxide and water in the presence of sunlight. During this process, oxygen is released.

Detailed explanation-2: -Plants, algae and cyanobacteria release oxygen during photosynthesis. Photosynthesis is also needed for carbon fixation.

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: -Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.

Detailed explanation-5: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
