Photosynthesis 1
The process that uses energy from the sun to make food from water and carbon dioxide.
What is photosynthesis?
What are the 3 major types of photosynthetic organisms?
Plants, Protists, Bacteria
Things that get or find their food.
What is a heterotroph?
Left side (before the arrow) in a chemical equation.
What is reactants?
The chemical formula for glucose.
What is C6H12O6?
The chemical that absorbs and stores the energy of sunlight.
What is chlorophyll?
Photosynthesis uses light energy, carbon dioxide, and ______ to produce oxygen and sugar.
What is water?
When the sun shines on a plant, the leaves can make food from carbon dioxide and ________.
What is water?
Producers that make their own food.
What is an autotroph?
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 stoma/stomata?
What are the 3 steps of photosynthesis?
Absorption of light energy
Conversion of light energy to ATP
Storage of energy as sugar
Photosynthesis takes place in these cell parts.
What are chloroplasts?
When we eat food, our body gets ________ from the carbohydrates stored in the food.
What is energy?
The product that is made from photosynthesis that humans need to survive.
What is oxygen?
What are the outputs of the light-dependent reactions? (Steps 1 and 2 of photosynthesis?)
ATP and O2
What color light waves are reflected by chlorophyll?
Green! (and yellow)
Where do the light-dependent reactions occur?
The thylakoid membrane
What are the 3 components of ATP
Adenine, Ribose sugar, 3 phosphate groups
The seven forms of electromagnetic radiation that come from the sun.
What is visible light, radio waves, microwaves, infrared, ultraviolet light, x-rays, and gamma rays?
What are the outputs of the Calvin cycle? (Step 3 of photosynthesis)
Glucose (sugar), ADP, NADP+
What is the chemical equation for photosynthesis?
6 CO2+ 6 H2O + Sunlight ---> C6H12O6 + 6 O2
What are the discs inside the chloroplast called?
Thylakoid. (Stacks of thylakoid are called Granum)
Why do plants have to make glucose instead of surviving off of ATP alone?
ATP is short-lived. They can only make ATP when there is sunlight. Sugar can be store for future use when there is no sunlight.
What happens during the Calvin cycle?
Carbon fixation (making glucose from CO2 and H2O)
