Compare the processes of photosynthesis and cellular respiration in terms of energy transformation.

• Photosynthesis converts chemical energy into light energy, while cellular respiration converts light energy into chemical energy.

• Photosynthesis converts light energy into chemical energy, while cellular respiration converts chemical energy into usable energy (ATP).

• Both processes convert chemical energy into light energy.

• Both processes convert light energy into chemical energy.

Analyze the impact of removing chlorophyll from a plant on its ability to perform photosynthesis.

• The plant would perform photosynthesis more efficiently.

• The plant would be unable to absorb sunlight, halting photosynthesis.

• The plant would produce more oxygen.
