The first step of photosynthesis is the absorption of light energy and the loss of electrons from chlorophyll . Photosynthesis is a process by the plant to produce food by absorbing light of a certain wavelength and used to convert water and carbon dioxide and minerals into oxygen-rich and energy-rich organic compounds.
What are the steps in photosynthesis?
| Stage Location Events | Light-dependent reactions Thylakoid membrane Light energy is captured by chloroplasts and stored as ATP | Calvin cycle Stroma ATP is used to create sugars that the plant will use to grow and live |

What is the first step of photosynthesis quizlet?
The first stage of photosynthesis is called the light reactions . During this stage, light is absorbed and transformed to chemical energy in the bonds of NADPH and ATP.
What are the 4 steps of photosynthesis?
It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP + to NADPH, (3) generation of ATP, and (4) conversion of CO 2 into carbohydrates (carbon fixation) .
What are the 5 steps of photosynthesis?
- 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.
Where does the first step of photosynthesis occur quizlet?
Where does the first stage of photosynthesis occur? Photosynthesis first occurs in the thylakoid membrane within the grana, inside the grana the light-dependent reactions of photosynthesis occur. An organism that is self-nourshing. It obtains carbon and energy without ingesting other organisms.
What is the process of photosynthesis Class 7?
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. ... The leaves of a plant can synthesise food because they contain a green pigment chlorophyll (which is necessary for making food).
What is photosynthesis explain with diagram?
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 are the two main reactions of photosynthesis?
Plant cell
The reactions that make up the process of photosynthesis can be divided into light-dependent reactions, which take place in the thylakoids, and light-independent reactions (also known as dark reactions or the Calvin cycle) , which take place in the stroma.
What is the process of photosynthesis in simple terms?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar .
What is the process of photorespiration?
Photorespiration is the process of light-dependent uptake of molecular oxygen (O 2 ) concomitant with release of carbon dioxide (CO 2 ) from organic compounds . The gas exchange resembles respiration and is the reverse of photosynthesis where CO 2 is fixed and O 2 released.
Where does each step of photosynthesis occur?
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 CO 2 .
Why is photosynthesis a 2 step process?
Photosynthesis represents the biological process by which plants convert light energy into sugar to fuel plant cells. Comprised of two stages, one stage converts the light energy into sugar , and then cellular respiration converts the sugar to Adenosine triphosphate, known as ATP, the fuel for all cellular life.
What is the last step of photosynthesis?
The last stage of the photosynthesis process is known as the Calvin-Benson cycle , in which the plant uses atmospheric carbon dioxide and water from soil to convert ATP and NADPH. The chemical reactions that make up the Calvin-Benson cycle occur in the stroma of the chloroplast.
What is step two of photosynthesis called?
Carbon atoms end up in you, and in other life forms, thanks to the second stage of photosynthesis, known as the Calvin cycle (or the light-independent reactions) .
What is the process of photosynthesis quizlet?
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 . Six molecules of carbon dioxide and twelve molecules of water, are consumed, while glucose, six molecules of oxygen and six molecules of water are produced.
