Photosynthesis 1
Location of photosynthesis in a plant cell
What is the chloroplast
This pigment is found in the thylakoid membranes of chloroplast and is required for photosynthesis
What is chlorophyll
The source of energy for photosynthesis
What is sunlight
Membrane where the light-dependent reactions occur
What is the thylakoid membrane
What is produced in the light-dependent reactions that is required for the Calvin cycle reactions
What are ATP and NADPH
Gas removed from the atmosphere during photosynthesis.
What is carbon dioxide?
Photosynthesis uses light energy, carbon dioxide, and ______ to produce oxygen and sugar.
What is water?
Accessory pigments that help chlorophyll absorb energy and protect chlorophyll from photo damage
What are carotenoids (beta carotene and xanthophylls)
This molecule absorbs energy from certain wavelengths/colors of light and energizes electrons
What is chlorophyll
Photosynthesis needs these three things to work.
What are sunlight, carbon dioxide, and water?
The tiny pores in the bottom of leaves that take in carbon dioxide from the air.
What are stomata?
This color (wavelength) of light is reflected by chlorophyll
What is green
Season in which deciduous trees drop their leaves
What is autumn or fall
The electron transport chain in the thylakoid membranes of chloroplasts actively transports this substance
What are H+ ions or protons
Most of the mass of the dry wood in a dead tree came from which reactant of photosynthesis
What is carbon dioxide (from the air)
The specific term for photosynthetic producers like cyanobacteria, algae, and plants that feed themselves with light energy
What are photoautotrophs
These colors (wavelengths) of light are absorbed by chlorophyll
What are violet, blue, and red
Why do the leaves of deciduous trees change color before they drop
What is the breakdown of chlorophyll pigment
The H+ or proton gradient was created by this process
What is active transport (from low to high concentration)
The Calvin cycle produces this product
What is carbohydrate (glyceraldehyde 3 phosphate)
The role or position in ecosystems that photosynthetic organisms have
What are producers
These reactants and energy sources are required for photosynthesis
What is carbon dioxide, water, and light energy (sunlight)
The type of cell in the leaves of plants that contain lots of chloroplasts and conduct photosynthesis
What are mesophyll cells
The H+ or proton gradient turns which protein complex in the thylakoid membrane
The ATP Synthase complex (ADP + phosphate -> ATP)
This molecule inhibits the carbon dioxide fixation step of the Calvin cycle
What is O2
