What is the primary purpose of photosynthesis?
Click to flip
The primary purpose of photosynthesis is to convert light energy into chemical energy stored in glucose.
Click to flip
Which organisms perform photosynthesis?
Click to flip
Photosynthesis is performed by plants, algae, and some bacteria.
Click to flip
Where in the plant does photosynthesis primarily take place?
Click to flip
Photosynthesis primarily takes place in the chloroplasts of plant cells.
Click to flip
What are the main reactants of photosynthesis?
Click to flip
The main reactants of photosynthesis are carbon dioxide (CO2) and water (H2O).
Click to flip
What is the main product of photosynthesis?
Click to flip
The main product of photosynthesis is glucose (C6H12O6), and oxygen (O2) is released as a by-product.
Click to flip
What pigment is responsible for absorbing light?
Click to flip
Chlorophyll is the pigment responsible for absorbing light, particularly in the blue and red spectrums.
Click to flip
What are the two main stages of photosynthesis?
Click to flip
The two main stages of photosynthesis are the Light-dependent reactions and the Calvin cycle (Light-independent reactions).
Click to flip
Where do the light-dependent reactions take place?
Click to flip
The light-dependent reactions take place in the thylakoid membranes of the chloroplasts.
Click to flip
What molecule is produced as a result of the light-dependent reactions?
Click to flip
ATP and NADPH are produced as a result of the light-dependent reactions.
Click to flip
In what part of the chloroplast does the Calvin cycle occur?
Click to flip
The Calvin cycle occurs in the stroma of the chloroplasts.
Click to flip
What is the role of ATP and NADPH in the Calvin cycle?
Click to flip
ATP and NADPH provide the energy and reducing power needed to convert carbon dioxide into glucose in the Calvin cycle.
Click to flip
How is oxygen produced during photosynthesis?
Click to flip
Oxygen is produced during the light-dependent reactions when water molecules are split in a process called photolysis.
Click to flip
What is the general chemical equation for photosynthesis?
Click to flip
The general chemical equation for photosynthesis is 6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.
Click to flip
What factors can affect the rate of photosynthesis?
Click to flip
Factors that can affect the rate of photosynthesis include light intensity, carbon dioxide concentration, temperature, and water availability.
Click to flip
What is the significance of photosynthesis to the Earth's ecosystem?
Click to flip
Photosynthesis is crucial for converting solar energy into chemical energy, producing oxygen, and forming the base of most food chains.
Click to flip
Why are leaves typically green?
Click to flip
Leaves are typically green because chlorophyll absorbs light most efficiently and reflects green light.
Click to flip
What is photolysis in the context of photosynthesis?
Click to flip
Photolysis is the process of splitting water molecules into oxygen, protons, and electrons during the light-dependent reactions.
Click to flip
How does carbon dioxide enter the plant for photosynthesis?
Click to flip
Carbon dioxide enters the plant through small openings in leaves called stomata.
Click to flip
What is the role of chlorophyll in photosynthesis?
Click to flip
Chlorophyll captures light energy from the sun, which is used to excite electrons to begin the photosynthesis process.
Click to flip
Why is the Calvin cycle also known as the light-independent reactions?
Click to flip
The Calvin cycle is called light-independent because it does not require light directly and uses the energy from ATP and NADPH produced in the light-dependent reactions.
