Photosynthesis and Respiration
What chemical equation sums up the events of photosynthesis? What does the arrow stand for?
6 CO2 + 6 H20 ---> C6H1206 + 602 carbon dioxide + water ---> sugar + oxygen an arrow connects the raw materials to the products
What is the equation for respiration?
C6H12O2 + 6O2 --> 6CO2 + 6H2O sugar oxygen carbon dioxide water
What substances are needed for photosynthesis? What substances are produced during photosynthesis?
Carbon dioxide and water, oxygen and sugar are the products.
How do plants obtain energy?
Plants get food from sunlight called photosynthesis. They use the energy from the sun and convert it into carbon dioxide and water into oxygen and sugars.
Is fermentation more likely to occur during a short run or a long walk?
Short run because you are going fast enough where you can't produce as much oxygen as you're taking in.
Would you expect a plant to produce more oxygen on a cloudy day or a sunny day?
Sunny day because that's where plants get their food so that's where/when the oxygen is produced.
pigment
colored chemical compounds that absorb light
Which process - photosynthesis or respiration - produces water?
photosynthesis
fermentation
provides energy for cells without using oxygen
stomata
small openings on the under sides of leaves
chlorophyll
the main photosynthetic pigment is chorophyll
photosynthesis
the process by which a cell captures energy in sunlight and uses it to make food
respiration
the process by which cells obtain energy from glucose
