NEET BIOLOGY

Detailed explanation-1: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Detailed explanation-2: -In most plants, the leaves are the main food factories. They capture the sun’s energy with the help of chlorophyll in the leaf cells. The chlorophyll traps and packages the energy from the light of the sun in a process called photosynthesis. Leaves usually have a large surface so they can collect the most sunlight.

Detailed explanation-3: -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-4: -Plants capture only about 1% of the solar energy that falls on them and use it for photosynthesis. The energy harnessed by the primary producers, flows in the food chain from producers to consumers to decomposers.

Detailed explanation-5: -Green plants convert solar energy to chemical energy by the process of photosynthesis. This reaction is directly or indirectly responsible for nearly all life on earth. During photosynthesis, carbon dioxide, a gas, is combined with water and solar energy, and converted to carbohydrates, a solid.
