Please choose the correct ending to complete the given sentence: Education and Communications: [header] How to explain photosynthesis [title] Discuss how plants create oxygen. [step] Photosynthesis is the process by which plants convert the sun's energy into chemical energy. The series of reactions used to do this conversion (referred to collectively as photosynthesis) creates molecular oxygen, o. this oxygen, which is critical for all other life on the planet, is released into the atmosphere.

Ending1: [substeps] If you are teaching children, you can summarize this by saying that plants take in the carbon dioxide that we breathe out, and turn it into oxygen. [title] Point out that plants create carbohydrates. Ending2: [title] Describe how a plant actually embodies oxygen. [step] This oxygen molecule, namely, atom, molecule, has a life stem (surface area of water and good air) and is formed into molecules in reaction to create oxygen. Ending3: For every energy atom consumed, a vacuum is created in the atmosphere. Unlike photosynthesis, plants don't synthesize oxygen just through the chemical energy atoms. Ending4: It forms and holds the food molecules that produce the oxygen and grows and then does, in turn, produce the plants this way. [substeps] A cell is inflated by nitrogen to transport oxygen to the cell.
