Question

1. halle is doing a report on photosynthesis. she draws a diagram to represent the materials used by plants to make food and the byproducts that this process produces. which is the correct diagram? (a) sunlight + carbon dioxide + water → sugar + oxygen (b) sunlight + oxygen + water → sugar + carbon dioxide (c) sunlight + carbon dioxide + sugar → water + oxygen (d) sunlight + oxygen + sugar → carbon dioxide + water

Explanation:

Photosynthesis is the process by which plants use sunlight, carbon dioxide (\(CO_2\)), and water (\(H_2O\)) to produce sugar (glucose) and oxygen (\(O_2\)). Option A correctly represents the reactants (sunlight + carbon dioxide + water) and products (sugar + oxygen) of photosynthesis. Option B has oxygen as a reactant which is incorrect (oxygen is a product). Option C has sugar as a reactant which is wrong (sugar is a product). Option D has incorrect reactants (oxygen and sugar) and products (carbon dioxide and water).

Answer:

A. sunlight + carbon dioxide + water → sugar + oxygen
