DENDROLOGY

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.

Detailed explanation-2: -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-3: -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.

Detailed explanation-4: -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-5: -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.
