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
