Question

which is the word equation for photosynthesis?
○ carbon + hydrogen + oxygen → glucose + water
○ glucose + water → carbon dioxide + oxygen
○ carbon dioxide + water → glucose + oxygen
○ glucose + oxygen → carbon + water + oxygen

Explanation:

Photosynthesis is a process in which plants use carbon dioxide and water (reactants) to produce glucose and oxygen (products) in the presence of sunlight. The first option is incorrect as it doesn't represent the actual reactants and products of photosynthesis. The second option has glucose as a reactant which is wrong (glucose is a product in photosynthesis). The fourth option also has incorrect reactants and products. The third option correctly shows carbon dioxide and water as reactants and glucose and oxygen as products.

Answer:

carbon dioxide + water → glucose + oxygen
