Detailed explanation-1: -They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels. Without this process, life on Earth as we know it would not be possible.
Detailed explanation-2: -The plant requires cellular respiration in order to release the bound chemical energy in the glucose and make ATP for the use of metabolic activities of the cell. Cellular respiration requires carbohydrates and oxygen. Hence, plants need to have the ability to find oxygen and carbohydrates.
Detailed explanation-3: -Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
Detailed explanation-4: -During photosynthesis, carbon dioxide, a gas, is combined with water and solar energy, and converted to carbohydrates, a solid. Formation of carbohydrates is a chemical way to store the sun’s energy as “food.” Carbohydrates produced from photosynthesis provide energy for all plant growth and maintenance.
Detailed explanation-5: -Plant carbohydrates, in the form of sugars are the energy source by which all plants carry out their major functions. All plants must photosynthesize, transpire and respire to survive. Sugar plays a vital role in all of these. Simple sugars are made by plants through the process of photosynthesis.
