Answer: Photosynthesis is a method of transforming light energy into chemical energy by phototrophs, which is later used to fuel cell functions. … When plants use light energy to turn carbon dioxide and water into glucose and oxygen, photosynthesis happens.

What is photosynthesis explain its mechanism class 10th?

photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

What is photosynthesis for class 7th?

The process by which green plants make their own food (like glucose) from carbon dioxide and water by using sunlight energy (in the presence of chlorophyll) is called photosynthesis. … Carbon dioxide + Water → Glucose + Oxygen. The process of photosynthesis takes place in the leaves of a plant.

What are the two mechanisms in photosynthesis?

Figure: The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.

What is photosynthesis in biology class 9?

Photosynthesis is a physiological process by which plant cells containing chlorophyll produce food in the form of carbohydrates by using carbon dioxide, water and light energy. Oxygen is released as a by-product.

What are types of photosynthesis?

There are two types of photosynthetic processes: oxygenic photosynthesis and anoxygenic photosynthesis. They both follow very similar principles, but oxygenic photosynthesis is the most common and is seen in plants, algae and cyanobacteria.

What kind of process is photosynthesis?

Photosynthesis is the physico-chemical process by which plants, algae and photosynthetic bacteria use light energy to drive the synthesis of organic compounds.

What is photosynthesis for 4th class?

Answer: photosynthesis is a process used by plants and other organisms to convert light energy into energy which is required for plants.

What is photosynthesis for kids?

Photosynthesis is the process in which green plants use sunlight to make their own food. … Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas. Chlorophyll is a substance in all green plants, especially in the leaves. Plants take in water from the soil and carbon dioxide from the air.

What is photosynthesis for 8th class?

Photosynthesis is the physico-chemical process by which plants can convert light energy into chemical energy, in the form of carbohydrate from simple inorganic substances like atmospheric carbon dioxide and water. Photosynthesis requires carbon dioxide, sunlight, water and chlorophyll as its basic raw materials.

Article first time published on

What is photosynthesis class 3rd?

Photosynthesis is the process in which green plants use sunlight to make their own food. Green plants use this light energy to change water and carbon dioxide into oxygen and nutrients called sugars.

What is photosynthesis for 5th class?

Photosynthesis is the big name for the process by which plants convert energy from sunlight into energy for food. This process also requires water and carbon dioxide. … When this happens the water, carbon dioxide and sunlight join together to form a sugar called glucose, plus water, and oxygen.

What are the machineries of photosynthesis?

Photosynthesis consists of the light and calvin cycle reactions. The light reactions are carried out by the thylakoid membrane protein complexes photosystem II (PSII), cytochrome b6/f complex, photosystem I (PSI), and ATP synthase.

What is photosynthesis by Brainly?

Photosynthesis is the process in which green plants use chlorophyll, sunlight, carbon dioxide and water to make their own food. … Photosynthesis is the process in which green plants use chlorophyll, sunlight, carbon dioxide and water to make their own food.

What happens photosynthesis?

During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. … Then, via respiration processes, cells use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product.

What are the 3 main stages of photosynthesis?

The three events that occur during the process of photosynthesis are: (i) Absorption of light energy by chlorophyll. (ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen. (iii) Reduction of carbon dioxide to carbohydrates.

What are three major processes of photosynthesis?

The three major events that occur during the process of photosynthesis are: > Absorption of light energy by chlorophyll. > Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.

Why is it called photosynthesis?

Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phōs (φῶς), “light”, and sunthesis (σύνθεσις), “putting together”.

What are the 4 steps of photosynthesis?

• Absorption of light. The first step in photosynthesis is the absorption of light by chlorophylls that are attached to the proteins in the thylakoids of chloroplasts. …
• Electron Transfer. …
• Generation of ATP. …
• Carbon Fixation.

What is photosynthesis in one word answer?

Photosynthesis is the process by which green plants prepare food with the help of sunlight,carbon dioxide, chlorophyll and water.

What is photosynthesis in biology class 6?

Hint: Photosynthesis is the process by which green plants prepare their own food with the help of carbon-dioxide, water, chlorophyll and light. By this process the light energy is converted into chemical energy.

What is photosynthesis in BYJU's?

Photosynthesis is a biological process utilized by all green plants to synthesize their own nutrients. The process of photosynthesis requires solar energy, water and carbon dioxide. The by-product of this process is oxygen.

What is chlorophyll class 4th?

Chlorophyll Definition Chlorophyll is a pigment present in all green plants and a few other organisms. It is required for photosynthesis, which is the process by which light energy is converted into chemical energy. The chlorophyll pigment is responsible for the green colouration in plants.

Is photosynthesis catabolic or anabolic?

Photosynthesis, which builds sugars out of smaller molecules, is a “building up,” or anabolic, pathway. In contrast, cellular respiration breaks sugar down into smaller molecules and is a “breaking down,” or catabolic, pathway.

Is photosynthesis a scientific principle?

Photosynthesis is the biological process that converts sunlight into chemical energy. … The primary light reactions occur with high quantum yield and drive free-energy-demanding chemical reactions with unsurpassed efficiency. Coupling of photosynthesis to hydrogenases allows some organisms to evolve H2.

Is chlorophyll involved in photosynthesis?

Green plants have the ability to make their own food. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll. … Chlorophyll is located in a plant’s chloroplasts, which are tiny structures in a plant’s cells. This is where photosynthesis takes place.

What are the end products of photosynthesis?

Though the final product of photosynthesis is glucose, the glucose is conveniently stored as starch. Starch is approximated as (C6H10O5)n, where n is in the thousands. Starch is formed by the condensation of thousands of glucose molecules.

What is the definition of photosynthesis quizlet?

Definition of Photosynthesis. Photosynthesis is the process by which green plants, algae and some forms of bacteria use energy from sunlight to convert carbon dioxide and water into glucose.

What materials are needed for photosynthesis?

To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant’s leaves, flowers, branches, stems, and roots. Plants also require water to make their food.
