Question

photosynthesis
photosynthesis is an important process that takes place in plants and other autotrophs, where they convert light energy from the sun into stored chemical energy in the form of glucose. this process primarily occurs in the chloroplasts of plant cells, which contain chlorophyll, the green pigment responsible for capturing light energy.
the overall chemical equation for photosynthesis can be represented as:
6co₂ + 6h₂o → c₆h₁₂o₆ + 6o₂
during the photosynthesis process, light energy is absorbed by chlorophyll and used to split water molecules into hydrogen and oxygen. the hydrogen combines with carbon dioxide to form glucose, while the oxygen is released into the atmosphere. this transformation of light energy into chemical energy is essential not only for the survival of plants but also for all living organisms that rely on plants for food and oxygen.

a
photosynthesis removes carbon dioxide from the atmosphere.
b
photosynthesis uses glucose in plants to make atp.
c
photosynthesis releases carbon dioxide into the atmosphere.
d
photosynthesis stores carbon as glucose in plants.
e
photosynthesis removes carbon from the soil

Explanation:

To solve this, we analyze each option:

• Option A: The photosynthesis equation is \(6\text{CO}_2 + 6\text{H}_2\text{O}

ightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2\). This shows \(\text{CO}_2\) (carbon dioxide) is taken from the atmosphere (as a reactant), so photosynthesis removes \(\text{CO}_2\) from the atmosphere.

• Option B: Photosynthesis produces glucose, and ATP is made in cellular respiration, not photosynthesis using glucose. Eliminate B.
• Option C: Photosynthesis releases \(\text{O}_2\), not \(\text{CO}_2\), into the atmosphere. Eliminate C.
• Option D: Photosynthesis converts light energy to chemical energy (stored in glucose), but the key here is about carbon movement. The equation shows \(\text{CO}_2\) (from atmosphere) is used, so A is more accurate about carbon removal from the atmosphere.
• Option E: Photosynthesis uses \(\text{CO}_2\) from the atmosphere, not carbon from the soil. Eliminate E.

Answer:

A. Photosynthesis removes carbon dioxide from the atmosphere.
