Photosynthesis Flashcards
(24 cards)
What is photosynthesis?
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.
What are the two main stages of photosynthesis?
The two main stages of photosynthesis are the light-dependent reactions and the Calvin cycle (light-independent reactions).
Where does photosynthesis take place in plants?
Photosynthesis takes place in the chloroplasts of plant cells.
What is the primary pigment used in photosynthesis?
The primary pigment used in photosynthesis is chlorophyll.
What is the role of light in photosynthesis?
Light is required in photosynthesis to provide energy for the process.
What is the overall chemical equation for photosynthesis?
The overall chemical equation for photosynthesis is 6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.
What are the products of photosynthesis?
The products of photosynthesis are glucose (C6H12O6) and oxygen (O2).
What is the source of the oxygen released during photosynthesis?
The oxygen released during photosynthesis comes from the splitting of water molecules.
What is the role of ATP and NADPH in photosynthesis?
ATP and NADPH are energy-carrying molecules that provide the necessary energy for the Calvin cycle.
What is the function of the Calvin cycle?
The Calvin cycle is responsible for the synthesis of glucose from carbon dioxide using ATP and NADPH.
True or False: Photosynthesis only occurs in plants.
False. Photosynthesis also occurs in algae and some bacteria.
What is the role of stomata in photosynthesis?
Stomata are small openings on the surface of leaves that allow for the exchange of gases during photosynthesis.
What is the importance of photosynthesis in the ecosystem?
Photosynthesis is crucial in the ecosystem as it is the primary source of energy for most living organisms.
What factors can affect the rate of photosynthesis?
Factors such as light intensity, temperature, and the availability of water and carbon dioxide can affect the rate of photosynthesis.
What is the role of the thylakoid membrane in photosynthesis?
The thylakoid membrane is where the light-dependent reactions of photosynthesis take place, including the synthesis of ATP and NADPH.
What is the significance of the Calvin cycle in photosynthesis?
The Calvin cycle is essential for converting carbon dioxide into glucose, which serves as a source of energy for the plant.
What is the relationship between photosynthesis and cellular respiration?
Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce ATP and carbon dioxide.
What role do pigments play in photosynthesis?
Pigments such as chlorophyll absorb light energy during photosynthesis and transfer it to the reaction center.
What is the importance of photosynthesis in the carbon cycle?
Photosynthesis is crucial in the carbon cycle as it removes carbon dioxide from the atmosphere and converts it into organic compounds.
How does the wavelength of light affect photosynthesis?
Different wavelengths of light can affect the rate of photosynthesis, with red and blue light being most effective due to their absorption by chlorophyll.
What is the role of rubisco in photosynthesis?
Rubisco is an enzyme that catalyzes the fixation of carbon dioxide during the Calvin cycle.
What is the role of the electron transport chain in photosynthesis?
The electron transport chain is responsible for generating ATP and NADPH during the light-dependent reactions of photosynthesis.
What is the significance of photosynthesis in providing oxygen for aerobic respiration?
Photosynthesis produces oxygen as a byproduct, which is essential for aerobic respiration in plants and animals.
What is the role of the light-harvesting complex in photosynthesis?
The light-harvesting complex is responsible for capturing light energy and transferring it to the reaction center in photosynthesis.
