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 the various steps of photosynthesis Class 10?
Solution
- Absorption of solar energy by the chlorophyll.
- Splitting of water into hydrogen and oxygen by this light energy.
- Conversion of solar energy into chemical energy.
- Reduction of carbon dioxide to form glucose by the transformed chemical energy.
What is class 3 photosynthesis?
Plants make their food using sunlight, water, carbon dioxide and nutrients and minerals from the soil. This process is called photosynthesis.
What are the 3 steps of cellular respiration?
Summary: the three stages of Aerobic Respiration
Carbohydrates are broken down using all three stages of respiration (glycolysis, citric acid cycle and the electron transport chain).
18 related questions foundWhat is the stages of photosynthesis?
Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle. Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO2.
How many steps are there in photosynthesis?
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 are the 2 stages of photosynthesis?
While there are many steps behind the process of photosynthesis, it can be broken down into two major stages: light-dependent reactions and light-independent reactions.
What are the 5 steps in photosynthesis?
What are the 5 steps of photosynthesis simple?
- 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.
- Step 4-Light Dependent.
- Step 5-Light independent.
- Step 6-Light independent.
- calvin cycle.
What is photosynthesis for class 10th?
Answer: 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.
What is the first step photosynthesis?
The first step in photosynthesis is the light reaction or photochemical reactions resulting in the formation of ATP and NADPH, which are later utilised in the biosynthesis process. In the first stage, light energy is captured and converted to chemical energy.
What are the 7 steps of photosynthesis?

What is the first stage of photosynthesis called?
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 hydrogen carrier NADPH and the energy-storage molecule ATP.
What are the 3 reactants of photosynthesis?
The reactants of photosynthesis are everything to the left of the "———>" arrow, thus the reactants of photosynthesis are carbon dioxide, water, and sunlight energy.
What are the 4 main steps of photosynthesis?
The overall process of photosynthesis can be objectively divided into four steps/ process:
- 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 happens in step 2 of photosynthesis?
Stage II is called the Calvin cycle. This stage combines carbon from carbon dioxide in the air and uses the chemical energy in ATP and NADPH to make glucose.
What is the first stage of photosynthesis in the chloroplast?
Photosynthesis begins with the light reactions. It is during these reactions that the energy from sunlight is absorbed by the pigment chlorophyll in the thylakoid membranes of the chloroplast.
What happens in phase 3 of the Calvin cycle?
In stage 3, RuBP, the molecule that starts the cycle, is regenerated so that the cycle can continue. Only one carbon dioxide molecule is incorporated at a time, so the cycle must be completed three times to produce a single three-carbon GA3P molecule, and six times to produce a six-carbon glucose molecule.
What is photosynthesis 4th grade?
Photosynthesisis a process by which plants make their own food in their leaves and give off oxygen and water that they are not using.
What are the two main stages of photosynthesis quizlet?
The two stages of photosynthesis are light reactions and the Calvin Cycle. Light reactions occur within the thylakoids and the Calvin Cycle takes place in the stroma. The light reactions create ATP and NADPH, which are used by the Calvin Cycle which also brings in carbon to produce sugar.
What are the by-product of photosynthesis?
The three important elements required for the photosynthesis process are Water, carbon dioxide and light. The product formed from this process, stored in the form of sugars, which are created from water and carbon dioxide. The by-product of the photosynthesis process is oxygen.
What is the main product of photosynthesis?
The products of photosynthesis are glucose and oxygen.
Although the hydrogen atoms from the water molecules are used in the photosynthesis reactions, the oxygen molecules are released as oxygen gas (O2). (This is good news for organisms like humans and plants that use oxygen to carry out cellular respiration!)
Where does Stage 2 of photosynthesis occur?
The light-dependent reactions take place in the thylakoid membranes in the granum (stack of thylakoids), within the chloroplast. Figure: The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions).
