Cellular Respiration/Photosynthesis

Maddie Muenster 6/7A

Photosynthesis!

  • Plant Cells have molecules that absorb light energy.
  • Molecules are called pigments.
  • Chlorophyll is found in chloroplasts
  • Chlorophyll (main pigment) gives plant green color.
  • Uses energy captured from chlorophyll to change carbon dioxide into food.
  • Sugar glucose is a carbohydrate. (found in photosynthesis.

Cellular Respration!

  • Respiration Means breathing but Cellular respiration is different.
  • During CR food is broken down into H2O or CO2 and energy is released.
  • ATP supplies energy that fuels the activity.
  • Takes place in the cell membrane.

Products and Reactants

Products and Reactants are what enters and leaves the cell.


Photosynthesis

Enters- Water and CO2

Leaves- Glucose sugar and H2O


Cellular Respiration

Enters- H2O and Glucose Sugar

Leaves- ATP, Carbon dioxide, and water

Diffrences!

  • Photo. takes place in chloroplasts when CR takes place in Mitochondria.
  • Photo. takes place in sun light when CR takes place all the time
  • CO2 and H2O enters for photo. when Glucose and Oxygen enters for CR
  • Glucose and Oxygen leaves for Photo. and CO2 and H2O leaves for CR
  • Energy sources for Photo. is light and CR is Chemical bonds.

Similarities!

  • ATP is a key molecule in each
  • Mitochondria of cell respiration and chloroplasts of photosynthesis have distinct similarities
  • Both use chemiosmosis to generate ATP
  • Both rely on movement of electrons for operation
  • Both use electron transport chains in production of ATP
