Photosynthesis and Respiration
Organisms that make their own food
Organisms which cannot make their own food
Small openings on the undersides of leaves
Substances that enter and exit the stomata
CO2 enters, O2 and water vapor exits
The process that provides energy without using oxygen
The process by which cells obtain energy from glucose
The products of photosynthesis
sugar and oxygen
The raw materials of photosynthesis
carbon dioxide and water
What happens during photosynthesis?
plants use energy from the sun to convert carbon dioxide and water into oxygen and sugars.
Where energy for ALL living things ultimately comes from
The green pigment in plants which traps sunlight to help them make sugar
The raw materials during respiration
oxygen and glucose
The products of respiration
carbon dioxide, energy (ATP) and water
The first stage of respiration takes place in this part of the cell
The second stage of respiration takes place in this part of the cell
How does fermentation differ form respiration?
it doesn't need oxygen and less energy is provided
The type of fermentation that sometimes occurs in human muscle cells
lactic acid fermentation
What happens during respiration?
cells break down simple food molecules such as sugar and release the energy they contain.
The respiration process that takes place inside cells
What happens during the first stage of respiration?
molecules of glucose are broken down into smaller molecules and oxygen is NOT involved and only a small amount of energy is released.
What happens during the second stage of respiration?
small molecules are broken down into even smaller molecules and these chemical reactions require energy and they release a great deal of energy
When you breathe in what do you take in?
The type of fermentation that takes place in yeast
What is the equation for photosynthesis?
6H2O + 6CO2 --(sunlight)--> C6H12O6 + 6O2
What is the equation for cell respiration?
C6H12O6 + 6O2 ----> 6H2O + 6CO2 + ATP
What is the first stage of photosynthesis?
capturing the sun's energy
What is the second stage of photosynthesis?
What captures light energy and uses it to power the second stage of photosynthesis and where does it take place?
What process creates energy from glucose (sugars) and takes place in the cytoplasm and mitochondria of an organisms cells?
How do autotrophs make their own food?
How do heterotrophs get food?
by eating other organisms
How do both autotrophs and heterotrophs create energy?
By going through cellular respiration
Can plant and animal cells go through cellular respiration?
Where does lactic acid fermentation in your body take place?
In your muscle cells when there is not enough oxygen
Where does alcoholic fermentation take place?
in yeast and some single celled organisms
