Fotossíntese Flashcards
Conhecer o processo de fotossíntese (26 cards)
What is photosynthesis?
Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose.
What are the main reactants of photosynthesis?
The main reactants of photosynthesis are carbon dioxide (CO2) and water (H2O).
What are the main products of photosynthesis?
The main products of photosynthesis are glucose (C6H12O6) and oxygen (O2).
In which organelle does photosynthesis occur?
Photosynthesis occurs in the chloroplasts of plant cells.
True or False: Photosynthesis only occurs in plants.
False: Photosynthesis also occurs in algae and some bacteria.
What pigment is primarily responsible for capturing light energy in photosynthesis?
Chlorophyll is the pigment responsible for capturing light energy.
Fill in the blank: The light-dependent reactions of photosynthesis take place in the __________.
thylakoid membranes.
What is the role of sunlight in photosynthesis?
Sunlight provides the energy needed to drive the chemical reactions of photosynthesis.
What is the equation for photosynthesis?
6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2.
What are the two main stages of photosynthesis?
The two main stages are the light-dependent reactions and the light-independent reactions (Calvin cycle).
Multiple Choice: Which of the following is NOT a product of photosynthesis? A) Glucose B) Oxygen C) Carbon Dioxide
C) Carbon Dioxide
What is the Calvin cycle?
The Calvin cycle is the set of light-independent reactions in photosynthesis that converts CO2 into glucose.
True or False: The oxygen produced in photosynthesis comes from water.
True.
What is the significance of photosynthesis for life on Earth?
Photosynthesis is crucial for producing oxygen and organic compounds that serve as food for most living organisms.
Which type of light is most effective for photosynthesis?
Red and blue light are most effective for photosynthesis.
Fill in the blank: The light-dependent reactions convert light energy into __________ energy.
chemical.
What role do stomata play in photosynthesis?
Stomata are small openings on leaves that allow CO2 to enter and O2 to exit.
What is the importance of chlorophyll in photosynthesis?
Chlorophyll absorbs light energy, which is essential for the photosynthesis process.
Multiple Choice: Which of the following factors can affect the rate of photosynthesis? A) Temperature B) Light Intensity C) Water Availability D) All of the above
D) All of the above.
What happens to the glucose produced during photosynthesis?
Glucose can be used for energy, stored as starch, or used to build other organic molecules.
True or False: Photosynthesis can occur without sunlight.
False.
What is photolysis in the context of photosynthesis?
Photolysis is the process of splitting water molecules using light energy during the light-dependent reactions.
What are the byproducts of the light-dependent reactions?
The byproducts of the light-dependent reactions are ATP, NADPH, and oxygen.
Fill in the blank: The main purpose of the light-independent reactions is to convert __________ into glucose.
carbon dioxide.
