cell energy test 5 Flashcards
whats the photosynthesis formula
C02 and water reacts with sunlight with chlorophyll to form glucose and oxygen
where does the light dep reaction occur
in the thykaloid
what happens in light dependant reaction
water is split into oxygens
what does water splitting into oxygen always require
sun light or light to be present
what is another naem for the light indpendant cycle
the calvin cycle
where does the calvin cycle occur
in the stroma
what happens in light independant reaction
carbon in converted into glucose
what is glucose
C6H12O6
what type of molecule is glucose
a monosaccaride
where does the plant absorb sunlight
on the leaves
why do only the leaves absorb sunlight
because they contain chlorophyll
why is chlorophyll green
because it absorbs other colors of the light spectrum but not green so green is reflected
how does phtotsynthesis gets its energy
by absorbing wavelengths of light
which wavelengths does chlorophyll absorb best
red and blue
which colors of the visible light spectrum have the most plant growth
red and blue
whihc colors of the visisble light spectrum have the least plant growth
green
what does white light do to plant growth
it makes it grow moderately
where does CO2 enter the plant
through the stomata
what do guard cells do
helps gas exchange , prevents excessive water loss
what is an open guard cell
turgid
what do guard cells cover
the stomata
where does H2O come from for photosynthesis
the roots
where do the plant’s nutrients come from
the roots
what type of membrane does a chloroplast have
a double membrane
