Photosynthesis is part of almost every plant's daily root-ine. But don't let that fool you; nearly all photosynthesis takes place in a plant's leaves, not its roots. There, the process of photosynthesis uses sunlight to turn non-food molecules into glucose, a sugar that stores chemical energy.

Question

Photosynthesis involves a series of chemical reactions. Carbon dioxide and water are the starting substances—the reactants—taken in through a plant’s leaves and roots. They react to form products. In the diagram below, the arrow points from the reactants to the products.

write an observation and correlate it to How do plants convert carbon dioxide into breathable oxygen?

Answer 1

Observation: During the daytime, leaves of plants appear vibrant and are often observed releasing bubbles of oxygen, especially under bright sunlight.

Correlation: This observation correlates with the process of photosynthesis, during which plants absorb carbon dioxide from the air through tiny openings in their leaves called stomata. Utilizing sunlight, which is absorbed by chlorophyll (the green pigment in leaves), plants convert carbon dioxide and water into glucose and oxygen. The oxygen produced as a byproduct is then released back into the atmosphere through the stomata, contributing to breathable oxygen for humans and other organisms. Therefore, plants play a crucial role in the oxygen-carbon dioxide cycle, acting as natural purifiers of the air and essential providers of oxygen.
