Which of the following statement is/are NOT true about photosynthesis?...
Explanation:
The correct answer is option D - P, Q, R, and S only. Let's break down each statement and determine whether it is true or not about photosynthesis:
P - Carbon dioxide is essential for photosynthesis to take place: This statement is true. Carbon dioxide is one of the key reactants required for photosynthesis. Plants take in carbon dioxide from the atmosphere through small openings called stomata on the surface of leaves.
Q - The products of photosynthesis are simple sugars: This statement is true. The primary product of photosynthesis is glucose, a simple sugar. Glucose is then converted into other carbohydrates, such as starch, which the plant uses for energy and growth.
R - Photosynthesis occurs in the green leaves of plants: This statement is true. Photosynthesis mainly occurs in the chloroplasts of the green parts of plants, including leaves. Chlorophyll, the pigment responsible for capturing light energy, is abundant in the chloroplasts of these green tissues.
S - Sunlight is not used as an energy source by plants to make food during photosynthesis: This statement is false. Sunlight is indeed used as an energy source during photosynthesis. The chlorophyll in the chloroplasts absorbs light energy from the sun and converts it into chemical energy, which is then used to power the synthesis of glucose and other organic molecules.
Therefore, the only statement that is NOT true about photosynthesis is statement S. Sunlight is a crucial source of energy for plants during the process of photosynthesis.
