Photosynthesis Review Fall 2013
Where does photosynthesis occur? In the chloroplasts
The light independent reactions involve this cycle: • The Krebs cycle • The Calvin cycle • The Citric Acid cycle • The Glycolysis cycle ☺
Light-dependent reactions require? Sunlight
True or False: Cells that do photosynthesis do not do cellular respiration? FALSE!!
Put these events in order:- Electron transport - Photosystem I- Photosystem II- Photolysis Photolysis Photosystem I Electron transport Photosystem II
What are three pigments commonly found in plants? Chlorophyll Carotenoids Phycobilins
Which pigment do you see primarily in the fall/autumn? Carotenoids
Which pigment do you primarily see in the spring/summer? Chlorophyll
What is the purpose of the mesophyll? Respiratory surface where gas exchange takes place and water is stored
What is responsible for different leaf colors? Their wavelength (determines what is absorbed or reflected)
Where does a plant get its biomass from? (Two places) • Water • Carbon dioxide
What is the purpose of photosynthesis? Converts light energy to glucose Allows plants to live and grow
What is the purpose of cellular respiration? Converts glucose to energy Allows animals to live and grow
Where does ATP Synthesis occur? Mitochondria
What two structures have multiple membranes that may indicate bacterial symbiosis? Chloroplasts Mitochondria
What is the difference between thylakoids and grana? Both are membraneous sacs Thylakoids are stacked Grana are interconnected sets of thylakoids
What is in the middle of the porphyrin ring of chloroplasts? Magnesium
What transfers electrons from photosystem II to the cytochrome complex? Plastoquinone
What carries electrons from the cytochrome complex to Photosystem I? Plastocyanin
What color is a green plant under a red light filter? Black Green is the only light reflected (red is absorbed)
What two things do plants need for photosynthesis to occur? Sunlight Carbon dioxide
What does photolysis literally mean? Using light to break water
What products of the light dependent reactions are used during the light independent reactions? ATP NADPH
What molecule transforms solar energy into an excited electron? ☺ • Chlorophyll • Carotenoids • Water • NADPH
Is the ph of the stroma acidic or basic? More basic
If you have a hydrogen gradient, which way will the H+ atoms move? From [high] to [low]
What two things may make your produce ripen faster? Temperature Oxygen
Name one reason that photosynthesis is important to animals. • Animals eat plants (somewhere in the food chain) • Plants produce oxygen so animals can breathe
How does water move from the roots of a plant to its leaves? Pressure (turgor) Guttation
Where is water stored in the leaf? Spaces in the mesophyll
What are two things you need to remember about science? • Curiosity • Skepticism
