The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question:** The question asks to select the incorrect statement regarding photosynthesis. We need to analyze each option carefully to determine which statement is false. 2. **Analyzing the Options:** - **Option 1:** "Plants require carbon dioxide from the atmosphere." - This statement is true. Plants take in carbon dioxide (CO2) from the atmosphere for photosynthesis. - **Option 2:** "Plants convert energy coming from the sun into chemical energy." - This statement is also true. During photosynthesis, plants convert light energy from the sun into chemical energy in the form of glucose. - **Option 3:** "Chemical energy produced by photosynthesis is used for the growth and sustenance of our biosphere." - This statement is true as well. The chemical energy stored in glucose is utilized by plants and other organisms for growth and sustenance. - **Option 4:** "CO2 is the source of O2 evolved." - This statement is incorrect. The oxygen (O2) produced during photosynthesis comes from the photolysis of water (H2O), not from carbon dioxide. Water molecules are split to release oxygen. 3. **Conclusion:** After analyzing all the options, the incorrect statement is **Option 4**: "CO2 is the source of O2 evolved." **Final Answer:** Option 4 is the incorrect statement regarding photosynthesis. ---
