Photosynthesis and Respiration Flashcards
What occurs during photosynthesis?
During photosynthesis, plants use the chemical chlorophyll to absorb solar energy (from the sun) then store this energy (in their chloroplasts) using a chemical reaction that creates carbohydrates.
H2O + CO2 –> CH2O + O2
The chemical reaction involves water and carbon dioxide. It breaks apart the carbon dioxide into just carbon and oxygen. Di (meaning two) dioxide.
-plants are giving off oxygen we need to breathe.
What is photosynthesis waste?
oxygen, which is good for us and other animals to respirate. Plants have little pours to take in carbon dioxide and oxygen, like we use our lungs to take in oxygen.
What happens during respiration in plants and animals?
During respiration, they take in oxygen and use it to reverse the chemical reaction of photosynthesis (plants), breaking down carbohydrates and releasing the energy stored in their chemical bonds.
What is the Krebb Cycle?
The process of storing energy through photosynthesis and later releasing it through respiration. (get their energy from the sun, store it, etc)
