What is photolysis?

• The process of breaking down organic compounds into inorganic molecules
• The process of breaking down water molecules using light energy
• The process of breaking down inorganic molecules into organic compounds
• The process of breaking down glucose molecules using heat energy

What is the process of separating pigments using chromatography?

• The process of separating pigments based on their solubility
• The process of breaking down pigments into their component parts
• The process of separating pigments based on their polarity
• The process of separating pigments based on their size

What is the primary and accessory pigments found in chloroplasts?

• Chlorophyll and xanthophylls
• Chlorophyll and phycobilins
• Chlorophyll and anthocyanins
• Chlorophyll and carotenoids

What is an independent variable?

• A variable that is measured in an experiment
• A variable that is manipulated by the experimenter
• A variable that is kept constant throughout an experiment
• A variable that is affected by the dependent variable

What is the difference between an action spectrum and an absorption spectrum?

• An action spectrum shows the wavelengths of light that are beneficial to photosynthesis, while an absorption spectrum shows the wavelengths of light that are harmful to photosynthesis
• An action spectrum shows the wavelengths of light absorbed by a pigment, while an absorption spectrum shows the wavelengths of light that drive photosynthesis
• An action spectrum shows the wavelengths of light that are harmful to photosynthesis, while an absorption spectrum shows the wavelengths of light that are beneficial to photosynthesis
• An action spectrum shows the wavelengths of light that drive photosynthesis, while an absorption spectrum shows the wavelengths of light absorbed by a pigment

What is visible light?

• Light that is only visible in the presence of oxygen
• Light that is only visible in the dark
• Light that is invisible to the human eye
• Light that has a range of wavelengths

What is photosynthesis?

• The process of converting light energy into heat energy
• The breakdown of organic compounds into inorganic molecules
• The synthesis of organic compounds from inorganic molecules using light energy
• The process of converting heat energy into light energy

What is a limiting factor?

• A factor that has no effect on the rate of photosynthesis
• A factor that enhances the rate of photosynthesis
• A factor that is not necessary for photosynthesis
• A factor that decreases the rate of photosynthesis

What is a pigment?

• A type of cell found in plants
• A molecule that absorbs light
• A type of sugar found in fruits
• A type of protein found in animals

What is the relationship between wavelength and energy?

• Wavelength and energy are not related
• Wavelength and energy have an inverse relationship
• Longer wavelengths have higher energy
• Shorter wavelengths have higher energy
