Question

Can plants survive without photosynthesis?

Answer 1

Photosynthesis is the process of converting light energy into chemical energy by the green plants. So during this process plants convert the light energy to the useful product which is used for their own purpose. In photosynthesis oxygen is the bi product and carbon dioxide is converted into useful products. Plants used sugar for the growth during photosynthesis.

Complete answer:
Plants using the photosynthesis process to make food from sunlight, carbon dioxide and water in the atmosphere. Getting energy from the photosynthesis process is the primary source of energy. So, photosynthesis is an important process because it produces oxygen as the end product. Without the photosynthesis process oxygen level will be reduced in the atmosphere. Photosynthesis plays a vital role in our daily life.
All human beings directly or indirectly depend on this natural process. This process is used to synthesize the food. First stage of photosynthesis is to break the water molecule by sunlight. Second stage of this process is called the Calvin cycle. Photosynthesis process takes two molecules of carbon and two molecules of water to form a one molecule of glucose. During autumn, plants change their color to perform photosynthesis. They use different pigments to perform this process because it is the essential one in green plants.

Note:
Without photosynthesis the carbon cycle will not happen because of low oxygen levels in the atmosphere. Sometimes chlorophyll is also used for the photosynthesis process and combined with carbon dioxide to produce the ATP. Living systems use this energy for charging. Photosynthesis process is used to maintain the oxygen and carbon level on earth.
