What Three Things Are Needed For Photosynthesis – Photosynthesis is the process by which green plants produce energy from sunlight. This happens at the cellular level in plant leaves and the way they produce oxygen and carbohydrates. Oxygen is released into the air, and carbohydrates, simple sugars, are used by plants to grow. To do photosynthesis, green plants need many things.
Chlorophyll, the pigment in plants that makes them green, is essential for the photosynthetic process. This chemical is produced by all green plants and its role in photosynthesis is to absorb light. Light energy causes the chemical reaction we know as photosynthesis.
What Three Things Are Needed For Photosynthesis
The system cannot function without energy input, which comes from the sun. The sun initiates the first reaction in photosynthesis, known as the light-dependent process. During photosynthesis, as sunlight stimulates chlorophyll, water splits into oxygen and hydrogen, and oxygen enters the atmosphere.

As any gardener knows, plants take water from the soil through their roots. Water moves up the plant through a complex transport system and reaches the leaves, to be used as a material during photosynthesis.
This gas is abundant in the air around plants. Many plants have a waxy coating on their leaves, which prevents them from drying out. Usually, it will also prevent gases such as carbon dioxide from entering the paper. But the leaf also has special openings, called stomata, that allow gases to enter the leaf cells. When photosynthesis occurs, the oxygen produced also leaves the cells through the stomata. Carbon dioxide combines with the hydrogen produced in the first process based on light, to produce carbohydrates. source of electricity, usually in the absence of sunlight. The earth supports the sun
Most life on Earth is based on a food chain that revolves around sunlight. Plants, algae and photosynthetic bacteria use the sun’s energy to turn carbon dioxide and water into sugar and oxygen through the process of photosynthesis. Photosynthesis is possible in any environment that receives enough sunlight – on land, in shallow water, even in and under clear ice.
However, in the ocean, there is no light. However, exploration of the oceans and environments of warm and cold climates has revealed an abundance of life. Here, instead of sunlight being the primary form of energy, chemical energy is used in a process called chemosynthesis.

Photosynthesis is the process by which plants, algae, and photosynthetic bacteria convert carbon dioxide and water into sugar (food), using energy from the sun.
Chemosynthesis was first observed as the basis of the food web in 1977 during an ocean research expedition near the Galápagos Islands. There, the researchers found the air above the sea to pour a soup of hot medicinal water on thriving communities of giant tubeworms. Surrounding these open spaces is a community of many new species of animals—thriving despite living in total darkness with no access to sunlight! These unique communities are found in tropical and subtropical climates around the world.
Chemosynthetic organisms, such as bacteria and archaea, form the base of the food web in air and cold water. Instead of photosynthesis, organisms use chemosynthesis, the process of making sugars (food) using energy released from chemical reactions. Unlike photosynthesis, there is no single chemical pathway that describes chemosynthesis. A variety of chemosynthetic organisms inhabit hydrothermal vents and cold-water regions, each using different methods to produce energy from the chemical-rich water that emerges from the floor of the ocean .
), is a common phenomenon in seafloor and subtropical waters. The diagram on the next page shows how tiny chemosynthetic microbes use the energy released from these chemical reactions to drive the carbon fixation process that converts inorganic carbon into sugars/nutrients (C).

Chemosynthesis is the process by which microbes make sugars (food) using energy released from chemical reactions. This method is used to create the main food web in hydrothermal vents and cold water areas. Chemosynthetic processes in vents and seeps vary depending on the different chemicals found in the water emerging from the ocean floor at these sites.
In a world without access to solar energy, chemosynthesis provides the basis for the development of rich, diverse societies. Deep-sea chemosynthetic bacteria form the base of a food web that includes a variety of marine life including oysters, tubeworms, clams, crabs, fish, and octopods, to name just a few.
Large colonies of chemosynthetic mussels grow near methane hydrates in the Gulf of Mexico.

Photosynthesis is critical to the existence of most life on Earth. This is the way in which almost all the energy in the biosphere is obtained by living things. As primary producers, photosynthetic organisms form the foundation of Earth’s food web and are directly or indirectly consumed by all higher life forms. Also, almost all the oxygen in the atmosphere is due to the process of photosynthesis. If photosynthesis stops, soon there will be little food or other living things on earth, most living things will disappear, Earth’s atmosphere will run out of oxygen.

. This means that the reactants, six molecules of carbon dioxide and six molecules of water, are converted by the heat energy obtained by chlorophyll (called energy) into sugar molecules and six oxygen molecules, that product. Sugar is used by the body, and oxygen is released as a by-product.
The ability to photosynthesize is found in both eukaryotic and prokaryotic organisms. The best known example is plants, as some parasitic or mycoheterotrophic species contain chlorophyll and produce their own food. Algae are the other dominant group of eukaryotic photosynthetic organisms. All algae, including large kelp and microscopic diatoms, are primary producers. Cyanobacteria and some sulfur bacteria are photosynthetic prokaryotes, the origin of photosynthesis. No animal is thought to be capable of photosynthesis on its own, although the emerald green sea slug can temporarily attach algae chloroplasts to its body for food production.
Photosynthesis, the process by which green plants and some other organisms convert light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to turn water, carbon dioxide, and minerals into oxygen and energy-rich water.
It is impossible to overstate the importance of photosynthesis in sustaining life on Earth. If photosynthesis stops, soon there will be less food or other things in the world. Most living things will disappear, and over time, the Earth’s atmosphere will be almost devoid of oxygen. The only organisms that can exist under such conditions are chemosynthetic bacteria, which can use the chemical energy of certain inorganic compounds and thus do not depend on the conversion of light energy.
What Are The Products Of Photosynthesis?
The energy from photosynthesis produced by plants millions of years ago is used for the fuel (ie, coal, oil, and gas) that keeps manufacturing society running. In the past, green plants and small carnivorous plants multiplied faster than they were eaten, and their bodies were deposited in the soil by sedimentation and other soil processes. There, protected from oxidation, these materials are slowly converted into fuel. These fossil fuels not only provide large amounts of energy used in industry, housing, and transportation but also serve as a raw material for plastics and other synthetic products. Unfortunately, modern civilization uses more than a few hundred years rather than the products of photosynthesis accumulated over millions of years. As a result, carbon dioxide removed from the atmosphere to produce carbohydrates in photosynthesis has been restored over millions of years at an alarming rate. The amount of carbon dioxide in the Earth’s atmosphere is increasing to the highest level it has reached in Earth’s history, and this is expected to have a major impact on the Earth’s climate.
The demands for food, materials, and energy in a world with a rapidly growing population have caused both the rate of photosynthesis and the efficiency of converting synthetic photons into products useful to humans to increase. .
