NEET BIOLOGY

Detailed explanation-1: -The Sun! The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas. After the sugar is produced, it is then broken down by the mitochondria into energy that can be used for growth and repair.

Detailed explanation-2: -Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.

Detailed explanation-3: -Choice (c) is correct. The products of cellular respiration are carbon dioxide and water, which are the raw materials for photosynthesis.

Detailed explanation-4: -photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Detailed explanation-5: -Complete explanation: Option A: The dark reaction can show up in absence of light however is established upon the end product of the light reaction. So, photosynthesis will no longer take place in the absence of light.
