Photosynthesis Flashcards
What is photosynthesis?
Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy stored in glucose.
What are the two main stages of photosynthesis?
The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).
Where does photosynthesis take place in plants?
Photosynthesis takes place in the chloroplasts of plant cells.
What are the inputs of photosynthesis?
The inputs of photosynthesis are carbon dioxide, water, and light energy.
What are the outputs of photosynthesis?
The outputs of photosynthesis are oxygen and glucose.
What pigment is responsible for capturing light energy in photosynthesis?
Chlorophyll is the pigment responsible for capturing light energy in photosynthesis.
What is the primary function of the light-dependent reactions in photosynthesis?
The primary function of the light-dependent reactions is to capture and convert light energy into chemical energy in the form of ATP and NADPH.
What is the primary function of the Calvin cycle in photosynthesis?
The primary function of the Calvin cycle is to use ATP and NADPH to convert carbon dioxide into glucose.
True or False: Photosynthesis occurs only in plants.
False. Photosynthesis also occurs in algae and some bacteria.
What gas is released as a byproduct of photosynthesis?
Oxygen gas is released as a byproduct of photosynthesis.
What is the role of water in photosynthesis?
Water is split during the light-dependent reactions to provide electrons for the photosynthetic process.
What is the overall chemical equation for photosynthesis?
The overall chemical equation for photosynthesis is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
What is the importance of photosynthesis in the ecosystem?
Photosynthesis is essential for producing oxygen, providing food for organisms, and maintaining the balance of carbon dioxide in the atmosphere.
Which part of the chloroplast is responsible for the light-dependent reactions?
The thylakoid membrane is responsible for the light-dependent reactions in photosynthesis.
What is the primary purpose of photosynthesis for plants?
The primary purpose of photosynthesis for plants is to produce glucose for energy and growth.
What is the role of ATP and NADPH in photosynthesis?
ATP and NADPH are used in the Calvin cycle to convert carbon dioxide into glucose.
What factors can affect the rate of photosynthesis?
Factors that can affect the rate of photosynthesis include light intensity, temperature, and the availability of water and carbon dioxide.
What is the function of the stomata in photosynthesis?
The stomata regulate the exchange of gases, such as carbon dioxide and oxygen, during photosynthesis.
What is the role of rubisco in photosynthesis?
Rubisco is an enzyme that catalyzes the first step of the Calvin cycle, where carbon dioxide is fixed into a stable form.
How does photosynthesis contribute to the carbon cycle?
Photosynthesis removes carbon dioxide from the atmosphere and converts it into organic compounds, playing a key role in the carbon cycle.
What is the relationship between photosynthesis and cellular respiration?
Photosynthesis produces glucose and oxygen, which are used as inputs in cellular respiration to generate ATP for cellular energy.
What environmental impact does photosynthesis have on reducing global warming?
Photosynthesis helps reduce global warming by removing carbon dioxide from the atmosphere and producing oxygen, which balances greenhouse gas levels.
What is the significance of photosynthesis in agriculture?
Photosynthesis is crucial in agriculture as it provides the basis for plant growth, crop yield, and food production for human consumption.
What is the role of light in photosynthesis?
Light energy is absorbed by chlorophyll and converted into chemical energy during photosynthesis.
