Before photosynthesis evolved, _________ was rare in Earths atmosphere.
|
02
|
|
Products of Photosynthesis are
|
Glucose and Oxygen
|
|
What structural feature of a leaf allows a leaf to obtain CO2 from the air?
|
Stomata
|
|
Vast majority of choloroplasts found in a leaf are located where?
|
Mesophyll
|
|
Specifically molecules of chlorophyll are located in membranes of sacs called...
|
thylakoids
|
|
What factors influence the rate of photosynthesis?
|
light intensity, temperature, CO2, water
|
|
What is not required at some state of green plant photosynthesis?
|
oxygen.
REQUIRED: ATP, NADP, WATER, CARBON DIOXIDE |
|
Cellular organelle of eukaryotic organisms which is responisble for photosynthetic activity is the...
|
choloroplat
|
|
scientist discovers a mutant plant seedling that appears to lack a stomata. Whats the effect?
|
CO2 would not be able to enter as a reactant for photosynthesis to occur
|
|
plant does not recieve an adequant amount of water, what is most affected by this?
|
Both the light dependent and lightindependent reactions of photosynthesis
|
|
the grana are disk-shaped, interconnected membranous sacs embedded in the stroma that form thlakoids when stacked on one another. T or F
|
false
|
|
majority of leafs chloroplasts are found in the mesophyll cells. T or F
|
true
|
|
chemical equation for photosynthesis?
|
6CO2+6H2O+light energy
|
|
how is the leaf adapted to capture energy from the sun and aquiring carbon dioxide and water?
|
C02 comes through adjustable pores, or stomata, and water comes from the vascular bundles (veins) to the mesophyll cells. leaves are broad and flat, so they provide a large surface area to the sun.
|
|
light dependent reactions occur in the
|
thylakoids
|
|
light indepedent reactions occur in the
|
stroma
|
|
the cells in the ____ layer of the leaf contain the mojority of a leafs chloroplasts
|
mesophyll
|
|
process of photosynthesis converts solar energy into ______ energy stored in the bonds of glucose
|
chemical
|
|
albino corn has no chlorophyll, you would expect these seedlings to ___________
|
fail to thrive
|
|
energy source in photosynthesis is...
|
visible light
|
|
energy is passed around different cholorphyll molecules until it reaches a specific chlorophyll molecule called the.....
|
reaction center
|
|
where are carotenoid pigments found?
|
in the thylakoid membranes of the chloroplasts
|
|
the pigments that absorb light energy to drive photosynthesis are
|
chlorophyll and carotenoids
|
|
pigment that absorbs red and blue light and reflects green light is
|
chlorophyll
