(a) Interpretation: If life were to exist elsewhere in the universe, it would require some process like photosynthesis. Concept introduction: The plants use the sun’s light energy to convert water and carbon dioxide to form energy-rich glucose molecules by the process of photosynthesis. Photosynthesis occurs in the chloroplasts of plants. Animals being heterotrophic consume plants or other animals for energy requirements.

Interpretation Introduction

(b)

Interpretation:

If the Starship Enterprise were to land on a distant planet and find no measurable oxygen in the atmosphere, could the crew conclude that photosynthesis is taking place or not.

Concept introduction:

Water acts as the electron donorin photosynthesis to produce glucose and oxygen. The absence of water hampers the process.

(a) It can be argued that, if life were to exist elsewhere in the universe, it would require some process like photosynthesis. Why is this argument reasonable? (b) If the starship Enterprise were to land on a distant planet and find no measurable oxygen in the atmosphere, could the crew conclude that photosynthesis is not taking place?

In photosynthesis, CO2 carbon atoms are transformed to glucose carbon atoms. (a) Are the CO2 carbon atoms being oxidized or reduced in this process? (b) Do the CO2 carbon atoms move to a higher or lower energy state in this process?

The law of conservation of matter states that no matter on earth can be created or destroyed. Using the following equation: 6H2O + 6CO2 + Sunlight—> C6H12O6 + 6O2, explain how the process of photosynthesis is an example of this.
