Where is the dark reaction located?
stroma
Dark reaction is also known as a carbon-fixing reaction. It is a light-independent procedure in which sugar molecules are created from the carbon dioxide and water molecules. The dark reaction happens in the stroma of the chloroplast, where they consume the products of the light reaction.
Which part of photosynthesis can take place in the dark?
What happens during the dark phase of photosynthesis? In the dark phase (which takes place in the stroma), the ribulose bisphosphate added to the carbon dioxide gas (CO2) in the air results in the production of organic compounds, principally carbohydrates or sugars, whose molecules contain carbon, hydrogen, and oxygen.
In which part of the chloroplast light and dark reaction take place?
Light reaction and dark reaction are the two types of sequential processes that occur during the photosynthesis of plants. Light reaction occurs in the thylakoid membrane of chloroplast whereas the dark reaction occurs in the stroma of the chloroplast.
Can photosynthesis occur at night?
No, plants do not perform photosynthesis at night. Photosynthesis is the process by which light energy is converted to chemical energy with the help of chlorophyll pigment, which absorbs light energy. Photosynthesis occurs in two stages, light reaction or photochemical phase and dark reaction or biosynthetic phase.
Does photosynthesis occur in the dark?
Plants need light to photosynthesize, but it doesn’t necessarily have to be sunlight. If the correct type of artificial light is used, photosynthesis can happen at night with lights that contain blue and red wavelengths.
In which light photosynthesis takes place faster?
As far as the rate of photosynthesis is concerned, it is fastest in white light making the rate of photosynthesis maximum. After white, we have violet light where photosynthesis occur to a higher extent as it has the shortest wavelength hence has the max energy.
Can photosynthesis occur in the night?
What are the end products of light reaction?
Difference between Light and Dark Reaction
| Light Reaction | Dark Reaction |
|---|---|
| The end products are ATP and NADPH. | Glucose is the end product. ATP and NADPH help in the formation of glucose. |
| The water molecules split into hydrogen and oxygen. | Glucose is produced. Co2 is utilized in the dark reaction. |
What is the other name of dark reaction?
The dark reaction was discovered by three scientists namely Calvin, Benson and Bassham and so this cycle is also called as the Calvin- Benson- Bassham cycle. This reaction is also called by many other names such as C3 cycle or reductive pentose phosphate cycle. The plants that have Calvin cycle are known as C3 plants.
Can photosynthesis occur in moonlight?
Oxygen is a byproduct of the photosynthesis process. Plants cannot perform photosynthesis in the moonlight because there is insufficient energy to excite chlorophyll molecules, i.e., reaction centres PS I and PS II, and thus light-dependent reactions are not initiated.
In which Colour the rate of photosynthesis is minimum?
green light
Therefore minimum photosynthesis takes place in green light. So, the correct answer is, ‘Blue and Green light.
What color has the highest rate of photosynthesis?
red light
White light appears to be the most effective light for photosynthesis, but apart from white, red light is also effective. When white light is not used, red is more effective than its counterparts, most likely because red light has a long wavelength that allows it radiate more energy and heat than other colors.
What are the six steps of photosynthesis?
When Leaves open their pores which is known as stomata.
What is the Order of events in 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 is the light cycle for 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 . The Calvin cycle, which takes place in the stroma,…
What is the first step in photosynthesis?
The first step in photosynthesis is the interaction of light with chlorophyll molecules. The chemical structures of the various chlorophyll molecules are based upon the cyclic tetrapyrrole that is also seen in the heme group of globins and cytochromes.
