Photosynthesis inputs and outputs in leaves

Steps:

• Identify process: Glucose formation in leaves is photosynthesis, using light, CO2, and H2O.
• List inputs: CO2 enters via stomata; H2O via roots and veins; light absorbed by chloroplasts.
• List outputs: O2 released through stomata; glucose stored or used.
• Match diagram: Select one showing CO2 and H2O entering, O2 exiting.

Why B is correct:

• B illustrates the photosynthetic equation (6CO2 + 6H2O + light → C6H12O6 + 6O2) with arrows for CO2/H2O in and O2 out.

Why the others are wrong:

• A: Omits water input, incomplete for photosynthesis.
• C: Shows O2 entering, reverse of photosynthetic gas exchange.
• D: Depicts respiration (O2 in, CO2 out), not glucose formation.

Final answer: B
