(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.

(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.
