The correct answers are:
1. cellular respiration and photosynthesis both involve water.
Water is broken down to form oxygen during photosynthesis, while in cellular respiration oxygen combined with hydrogen forms water.

2. cellular respiration uses sugar, and photosynthesis produces sugar. Photosynthesis makes the glucose that is used in cellular respiration to make ATP.

The two statements that correctly describe one similarity and one difference between cellular respiration and photosynthesis are:

  • Cellular respiration and photosynthesis both involve water.

  • Cellular respiration uses sugar, and photosynthesis produces sugar.

The water is used for the chemical and biochemical processes that support the metabolism of the plant.

Cellular respiration involves the splitting of pyruvic acid (produced by glycolysis) into carbon dioxide and water, together with the production of adenosine triphosphate (ATP) molecules.

  • Energy is released through the stepwise breakdown of sugar (glucose) and other molecules.

Photosynthesis is the metabolic process by which green plants convert inorganic substances (carbon dioxide and water) into organic substances.

  • The plant uses sunlight to separate water into hydrogen and oxygen.

  • Hydrogen then uses carbon dioxide in the air to form sugar, while oxygen is discharged into the atmosphere and forms water vapor.

Therefore, we can conclude that cellular respiration and photosynthesis both involve water and they differ in cellular respiration uses sugar, and photosynthesis produces sugar.
