What is photosynthesis short answer?
Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight and turn it into chemical energy.
What is photosynthesis explain?
Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the “fuel” used by all living things.
What is photosynthesis kid definition?
Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis is necessary for life on Earth. Green plants use this light energy to change water and carbon dioxide into oxygen and nutrients called sugars.
Why is 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. The importance of photosynthesis in our life is the oxygen it produces.
What is the best definition of photosynthesis?
: synthesis of chemical compounds with the aid of radiant energy and especially light especially : formation of carbohydrates from carbon dioxide and a source of hydrogen (such as water) in the chlorophyll-containing cells (as of green plants) exposed to light.
What is photosynthesis with diagram?
Through a process called photosynthesis, plants use energy in sunlight to turn a gas called carbon dioxide and water into sugar. Plants then use this sugar to grow. At the same time, plants produce a gas called oxygen as a waste product, which is lucky for us and other animals because we need oxygen to breathe!
Why is photosynthesis important to humans?
Plants make their own food and pass there energy down to humans when we consume the nutrients from the plants. Photosynthesis creates clean air for humans to breathe. It also allows plants to grow, which feeds humans .
Which is the first step of photosynthesis?
Photosynthesis occurs in two stages. In the first stage , light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH. During the second stage , the light-independent reactions use these products to capture and reduce carbon dioxide.
Do plants take in oxygen?
During photosynthesis, plants absorb carbon dioxide and release oxygen . Adding plants to interior spaces can increase oxygen levels.At night, photosynthesis ceases, and plants typically respire like humans, absorbing oxygen and releasing carbon dioxide.
What is photosynthesis explain with example?
The definition of photosynthesis is the process through which plants use water and carbon dioxide to create their food, grow and release excess oxygen into the air. An example of photosynthesis is how plants convert sugar and energy from water, air and sunlight into energy to grow.
What is photosynthesis step by step?
Photosynthesis Definition. Photosynthesis equations/reactions/formula. Carbon dioxide + Water + solar energy → Glucose + Oxygen. 6CO2 + 6H2O + solar energy → C6H12O6 + 6O2. Carbon dioxide + Water + solar energy → Glucose + Oxygen + Water.
What are the steps of photosynthesis simple?
Terms in this set (7) Step 1-Light Dependent. CO2 and H2O enter the leaf. Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2. Step 3- Light Dependent. The electrons move down to enzymes. Step 4-Light Dependent. Step 5-Light independent. Step 6-Light independent. calvin cycle.
Does photosynthesis produce oxygen?
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
What are the benefits of photosynthesis?
Through photosynthesis, green plants and cyanobacteria are able to transfer sunlight energy to molecular reaction centers for conversion into chemical energy with nearly 100% efficiency. Speed is the key as the transfer of the solar energy takes place almost instantaneously such that little energy is wasted as heat.
Do plants need food?
Plants , like all living things, need food to survive. Plants make their food using a process called photosynthesis, which means “putting together through light.” During photosynthesis, a plant traps energy from sunlight with its leaves. The plant uses the glucose as a food to help it stay alive and grow.
