The process shown in the diagram is Photosynthesis (option D)
What is photosynthesis?
Photosynthesis stands as an important process by which green plants, algae, and certain bacteria harness light energy, usually from the sun, and convert it into chemical energy. This intricate conversion unfolds within the chloroplasts of plant cells, chiefly employing chlorophyll, a light-absorbing pigment.
Within photosynthesis, carbon dioxide (CO2) sourced from the atmosphere and water (H2O) amalgamate under the influence of light energy, yielding glucose (a sugar variant) and oxygen (O2) as consequential products.
