Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.Nov 22, 2019
The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet’s living systems are powered by this process.
Plants don’t eat food; they have to create it for themselves. They do this through a process known as photosynthesis. Photosynthesis uses water, carbon dioxide from the air and energy from the sun or another light source to create glucose or sugar. This glucose provides the energy the plant needs in order to survive.
The reactants of this process are sunlight, water, and carbon dioxide, and the products are oxygen and energy. The photosynthesis process helps provide oxygen in the atmosphere, which is essential for respiration because animals, especially humans, would die in the absence of oxygen.
(4) The role of Sunlight in photosynthesis – The sunlight supplies energy for the food making process called photosynthesis. The sun’s energy is captured by plant leaves with the help of chlorophyll and converted into chemical energy of food. This chemical energy gets stored in the form of plant food.
Photosynthesis is a physio-chemical process which uses light energy to produce organic compounds. Photosynthesis is essential as it not only is the primary source of food for living entities but it also releases oxygen into the atmosphere which is required to breathe.
The process of photosynthesis is important to all life on Earth because through this process, oxygen is released into the atmosphere. Without oxygen, living things on Earth, would not survive.
Photosynthesis is very important because almost all living things depend on plants for food. Photosynthesis is also important because of the oxygen it produces. Humans and other animals need to breathe in oxygen to survive. Some living things other than plants also make their own food through photosynthesis.
Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die.
Phytoplankton, such as algae, are the plants that make photosynthesis happen in the ocean. These tiny plants live on the surface of the water where they collect their energy from the sun and use it along with nutrients in the water to grow and feed ocean life.
Significance of Photosynthesis:
Photosynthesis is the main way through which the solar energy is made available for different living beings. Green plants are the main producers of food in the ecosystem. All other organisms directly or indirectly depend on green plants for food.
Cellular respiration and photosynthesis are biological processes in which matter and energy flow through the biosphere. These two processes are responsible for the exchange of oxygen and carbon dioxide between living organisms and the environment.
The emission of electrons from chlorophyll takes place by the absorption of light through chlorophyll, the electron emitted is then carried through many different electron carriers and then these electrons are further used in the photolysis of water and also releases ATP and NADH.
Fungi use photosynthesis to decompose dead and decaying plant matter. C) Cold-blooded animals use photosynthesis to convert sunlight into energy for cell functions. … The process of photosynthesis is energy-releasing because the process converts light energy into free energy that can be used for cell functions.
Glucose is the six carbon sugar that is the main product of photosynthesis. Water and carbon dioxide are the reactants in photosynthesis.
Photosynthesis is the main source of food on earth. It releases oxygen which is an important element for the survival of life. Without photosynthesis, there will be no oxygen on earth. The stored chemical energy in plants flows into herbivores, carnivores, predators, parasites, decomposers, and all life forms.
Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas as raw materials. … Plants take in water from the soil and carbon dioxide from the air.
Photolysis of water is a important part of the process of photosynthesis. Because we know that energy currency which is used in plants is NADPH(Nictinamide Adenine Diphosphate ; hydrogen) and ATP but from where the hydrogen of NADPH comes. It is gained by the photolysis of water into hydrogen ions and oxygen.
The light reactions of photosynthesis use energy from photons to generate high-energy electrons (Figure 19.2). These electrons are used directly to reduce NADP+ to NADPH and are used indirectly through an electron-transport chain to generate a proton-motive force across a membrane.
The transfer of electrons in a step-by-step fashion in Photosystems I and II releases energy and heat slowly, thus protecting the chloroplast and cell from a harmful temperature increase. It also provides time for the plant to form NADPH and ATP.
Why is photosynthesis so important? It is the process that plants use to make their own food so that they become the base of the food chain. It produces oxygen that all living things need for cellular respiration.
How is photosynthesis important to a food web? Plants use sunlight and carbon dioxide, which comes from other animals in the food web. Using these materials, they make oxygen, which they give off to other organisms, and glucose. Photosynthesis keeps a plant alive, and also provides food for organisms.
Why is photosynthesis important? Because it converts sunlight energy into chemical bond energy.
Plants are really important for the planet and for all living things. Plants absorb carbon dioxide and release oxygen from their leaves, which humans and other animals need to breathe. Living things need plants to live – they eat them and live in them. Plants help to clean water too.
The photosynthetic process produces several products. … Water is also a product of photosynthesis. This water is produced from the oxygen atoms in the carbon dioxide molecules. The oxygen molecules released into the atmosphere come exclusively from the original water molecules, not from the carbon dioxide molecules.

The three main types of photosynthesis are C3, C4, and CAM (crassulacean acid metabolism). In college I had to memorize some of their pathways and mechanisms, but I will highlight what gives one an advantage over another and what types of crops, forages, and weeds have specialized C3 and C4 photosynthesis.
We conclude that, although photosynthesis may contribute to O(2) provision, its main role is to reduce the dependence of the insect-induced gall on the host plant for photosynthates, thereby reducing intra-plant, inter-gall competition and enhancing the probability that each gall will reach maturity.
