What is the structure of chloroplast in photosynthesis?
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
What process occurs in the chloroplast?
In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.
In which part of the chloroplast does each stage occur?
In which part of the chloroplast does each stage occur? Light reactions happens in the thylakoid membrane, and the calvin cycle happens in the stroma.
How does chloroplast structure affect photosynthesis?
Just like the structure of the mitochondria was important to its ability to perform aerobic cellular respiration, the structure of the chloroplast allows the process of photosynthesis to take place. Both the light-dependent reactions and the Calvin cycle take place inside of the chloroplast.
How does the structure of the chloroplast facilitate its function?
The structure of the chloroplast is adapted to the function it performs: Thylakoids – flattened discs have a small internal volume to maximise hydrogen gradient upon proton accumulation. Grana – thylakoids are arranged into stacks to increase SA:Vol ratio of the thylakoid membrane.
Where in the chloroplast do the light reactions occur?
the thylakoid discs
The light reaction takes place in the thylakoid discs. There, water (H20) is oxidized, and oxygen (O2) is released. The electrons freed up from water are transfered to ATP and NADPH. The dark reaction occurs outside of the thylakoids.
What occurs in photosynthesis?
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
Which structure is found only in plant cells and functions in the process of photosynthesis?
chloroplast, structure within the cells of plants and green algae that is the site of photosynthesis, the process by which light energy is converted to chemical energy, resulting in the production of oxygen and energy-rich organic compounds.
What occurs in the stroma of a chloroplast?
The light-independent reactions of photosynthesis are carried out in the chloroplast stroma, which contains the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (rubisco).
How photosynthesis occurs in plant?
Which of the reaction occur in photosynthesis?
6. Which one chemical reaction occurs during photosynthesis? explanation – the chemical reaction that occurs during photosynthesis means Carbon dioxide is reduced and water is oxidised .
