Untitled Deck Flashcards
What are chloroplasts?
Organelles in plant cells that change energy from the sun to chemical energy.
What is chlorophyll?
A green pigment in plants that helps a plant gather the sun’s energy.
How does light travel?
Light travels in waves.
What do green leaves do?
Reflect green light waves and absorb all other colors.
What are accessory pigments?
Pigments that assist in photosynthesis, including chlorophyll (green), xanthophyll (yellow), and carotene (orange).
What are thylakoids?
Small sacs stacked on top of each other that store chlorophyll.
What is a granum?
A stock of thylakoids.
What is the stroma?
The fluid that fills chloroplasts.
What is the photosynthesis chemical equation?
6H2O + 6CO2 + Sunlight → C6H12O6 + 6O2 (water + carbon dioxide + sunlight + sugar + oxygen).
What are stomata?
Openings on the undersides of leaves that allow gas exchange to occur.
Where do light reactions occur?
In thylakoids.
What do light reactions need?
Light.
What goes in and comes out during light reactions?
H2O goes in and O2 comes out.
What happens to ADP and NADP during light reactions?
ADP + P is converted to ATP and NADP is converted to NADPH.
NADPH is a coenzyme that carries electrons.
Where does the Calvin Cycle occur?
In the stroma.
