|
|
During photosynthesis, what is both consumed and measured?
|
CO2.
|
|
The effects of cell respiration can be studied when leaves are in the _____.
|
Dark (while there is no photosynthesis uptake of carbon dioxide).
|
|
During the light, which reaction(s) are occuring?
|
Both photosynthesis and cell respiration.
|
|
Which reaction is carried out at all times?
|
Cell respiration.
|
|
When does photosynthesis occur?
|
When green plant cells are exposed to LIGHT.
|
|
How do we find cell respiration?
|
Total in light - total in dark.
|
|
How is the presence of photosynthesis tested?
|
INDIRECTLY by using IKI Test for starch.
|
|
The presence of starch identified by IKI is an indirect indicator of _______.
|
Photosynthesis.
|
|
Photosynthesis requires which type of Chlorophyll?
|
Chlorophyll A.
|
|
Why does photosynthesis require Chlorophyll A?
|
Green areas of leaf contain Chlor. A and that is where most photo occurs/starch is found.
|
|
What is the red pigment?
|
Anthocyanin.
|
|
Anthocyanin is water soluble because ______.
|
Red pigment can be removed by boiling water.
|
|
Do white areas on leaves have pigment?
|
No.
|
|
What pigments makes up the brick color in a Coleus leaf?
|
Both anthocyanin and Chlorophyll.
|
|
Is Chlorophyll water soluble like Anthocyanin?
|
No.
|
|
What will remove the green color in a Coleus leaf?
|
Boiling Alcohol.
|
|
What is the main photosynthetic pigment?
|
Chlorophyll A.
|
|
What are the antenna pigments?
|
Chorophyll B, carotenes and xanthophylls.
|
|
What is the technique to separate a mixture of solutes in same solution?
|
Paper chromotography.
|
|
How does solvent move up on paper during paper chromotography?
|
By capillary action (adhesion + cohesion).
|
|
Why do pigments move at different rates during paper chromotography?
|
1) Size of pigment
2) Solubility of pigment in solvent 3) H bond to paper |
|
What does the absorption spectrum plot?
|
Wavelength of light (nm) vs. absorption

|
On an absorption spectrum plot, which axis is the Wavelength of light?
|
X Axis.
|
|
On an absorption spectrum plot, which axis is the absorption?
|
Y Axis.
|
|
What machine is used to measure absorption spectrum?
|
Spectrophotometer.
|
|
How is pigment extracted from chromotography strips?
|
By using acetone.
|
|
On spectrophotometer, it is set to 100% only for ____.
|
Acetone.
|
|
What is the color range associated with the wavelengths 400 - 700 nanometers (nm)?
|
Color range of violet through red.
|
|
The visible colors from shortest to longest wavelength.
|

|
|
The visible colors from longest to shortest wavelength.
|
ROY G. BIV
|
|
During photosynthesis, what color light is NOT absorbed and is reflected back?
|
Green light.
|
|
Name the order of pigments from furthest to nearest.
|
Carotene, xanthophylls, chlorophyll a, lastly chlorophyll b.
|
|
Why do leaves change color in autumn?
|
Because pigments are replaced in PLASTIDS.
