NEET BIOLOGY

Detailed explanation-1: -Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls. Starch is stored in seeds and other plant parts as a food source.

Detailed explanation-2: -Inside the chloroplasts within leaves, light, water (H2O), and carbon dioxide (CO2) are transformed into energy and sugar (glucose). Using water, sunlight is converted into energy-storing molecules within the plant cells. The energy from these molecules is then used to create glucose from CO2.

Detailed explanation-3: -Glucose is made as a by-product in the process of photosynthesis because glucose contains much more energy as compared to ATP. During photosynthesis, light energy is converted to chemical energy and is stored in the form of glucose and gets transported to the various parts of the plant.

Detailed explanation-4: -Plants rely on the energy in sunlight to produce the nutrients they need. But sometimes they absorb more energy than they can use, and that excess can damage critical proteins. To protect themselves, they convert the excess energy into heat and send it back out.

Detailed explanation-5: -After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.
