photosynthesis quiz Flashcards
define stomata
tiny pores in leaves
the Calvin cycle is a series of reactions that converts ___ to ___ which are eventually joined together to make ___.
what is the source of energy used for these reactions?
Carbon dioxide
G3p
glucose
ATP and NADPH
what is rubisco
the enzyme that attaches the molecule of co2 to the 5-carbon molecule RuBP
what wavelength of light are plants to able to use?
why do they appear this color?
green wavelength
light is reflected
what is dehydration in plants?
water loss through the stomata of leaves
how do plants respond to minimize this problem?
what additional problem does this cause?
they close their stomata to conserve water
oxygen increase and CO2 decrease
what happens during photorespiration?
why is this process considered wasteful?
oxygen is added to the Calvin Cycle instead of carbon dioxide
bc no ATP or sugar is produced
what do C4 plants do to minimize photorespiration?
by moving the carbon fixation process to the mesophyll
what do CAM plants do to minimize photorespiration?
they only open their stomata at night when the air is cooler
what is the purpose of light independent reactions?
what is the source of carbon for this process?
to generate glucose
Carbon dioxide
