Mesophull cells and guard cells
2
Q
Organelle site of PS
A
Chkoroplast
3
Q
Site of light rxn
A
Thylakoids/ granum
4
Q
Site of dark rxn
A
Stroma
5
Q
How is chlorophyll being fixed by stratum / thylakoids????
A
My is inserted next to phosolipid belayer
6
Q
Colours that chlorophyll ABSORB
A
Blue/violet
Orange/red
7
Q
Colours chlorophyll REFLECT
A
Green
8
Q
Organ site of PS in plants
A
Leaf and green stem
9
Q
- Leaves are mostly green in colour becausesunlight is mainly composed of green light.green is easily seen by us.green light is more useful for photosynthesis.chlorophyll molecules do not absorb green light.
A
chlorophyll molecules do not absorb green light.
10
Q
- Chlorophyll molecules are foundassociated with the thylakoid membrane of chloroplasts.in the stroma of chloroplasts only.evenly distributed in the chloroplast.in mitochondria.
A
associated with the thylakoid membrane of chloroplasts.
11
Q
- During photosynthesis of green leaf cells, the oxygen comes fromwatercarbon dioxideglucoseATP
A
water
12
Q
- When light strikes chlorophyll molecules, they lose electrons. These lost electrons will soon be replaced by electrons formed fromBreaking down ATPPhotolysis of waterFormation of NADPH from NADPCellular respiration
A
Photolysis of water
13
Q
- The primary function of the light-dependent reactions (i.e. light reactions) of photosynthesis is toproduce oxygen by removing electrons from water.produce carbohydrates from carbon dioxide and water.produce energy-rich ATP and NADPH.create an electron gradient that drives ATP synthesis.
A
produce energy-rich ATP and NADPH.
14
Q
- In photosynthesis, the dark reaction (or known as light-independent reactions) consist ofConverting carbon dioxide into sugarsSplitting hydrogen and oxygen from waterChlorophyll absorbing light energyUptake of glucose for photosynthesis
A
Converting carbon dioxide into sugars
15
Q
- In green plants, the enzymes for carbon fixation are found in thechloroplast stroma.chloroplast grana.stromal lamellae.cytosol (i.e. cytoplasm).
A
stromal lamellae.
