photosynthesis Flashcards
what do plants use for their source of energy?
light
what is the reaction that plants use to trap their energy called?
photosynthesis
where does photosynthesis take place?
in the leaves of the plant
is photosynthesis endothermic or exothermic?
endothermic, because it takes in energy
what green chemical in plants can absorb light energy?
chloropyhll
what is the word equation for photosynthesis?
carbon dioxide + water -> glucose + oxygen
at the first stage, the plant takes what into the leaf?
water and carbon dioxide
what is absorbed by chlorophyll?
light energy
what is light energy used to convert carbon dioxide and water into?
glucose
what is the chemical equation for photosynthesis?
CO2 + H20 -> C6 H12 O6 + O2
as we increase light intensity, how is the rate of photosynthesis affected and why?
rate increases because plant has more light energy to carry out photosynthesis
what are the 4 limiting factors of photosynthesis?
amount of carbon dioxide, light intensity, amount of chlorophyll in leaf and temperature
if temp is too high, what happens?
enzymes are damaged and rate falls
as we increase temp, what happens?
enzymes work faster
