What are the standard Rf values for pigments involved in photosynthesis?
carotene - 0.98 chlorophyll a - 0.59 chlorophyll b - 0.42 pheophytin - 0.81 xanthophyll 1 - 0.28 xanthophyll 2 - 0.15 everything is in percentages
What pigments do Nannocloropsis oculata utilize to photosynthesize?
These algae utilize chlorophyll a in photosynthesis. There is a big difference between the species of this genus with other microalgae. Nannocloropsis algae have neither chlorophyll b nor chlorophyll c.
Why are these pigments unstable in the presence of light or heat energy?
Chlorophyll: Reaction with heat depends on pH. In a basic solution (pH 9), chlorophyll is stable, and in an acidic solution (pH 3) it is unstable. When heated, the cell membrane of the plant deteriorates, releasing acids, which decrease the pH. This results in the magnesium atom being displaced by two hydrogen ions, resulting in the formation of olivebrown pheophytin complex. This cell degradation during heating also makes the chlorophyll more susceptible to photo-degradation. *When chlorophyll undergoes heat process, it will turn dull olive brown.
What is the pH range safe for chlorophyll stability?
The chlorophyll is usually acidic. The PH range for safe chlorophyll stability should be between a PH of seven and nine.
What is the relationship between pigments and chlorophyII?
Chlorophyll is a pigment.
Why is pheophytin less polar than chlorophyll?
Pheophytin and Chlorophyll are similar in there makeup. The difference between the two is that the magnesium ion is replaced by hydrogen making it less polar.

What is pheophytin?
Grey
What color is pheophytin?
Grey
What is a difference between chlorophyll A and chlorophyll B?
The structural difference between chlorophyll 'a' and chlorophyll 'b' is this that the functional group bonded to the porphyrin is methyl group (-CH3) in chlorophyll 'a' and carbonyl group (-CHO) in chlorophyll 'b'.
What function of Pheophytin?
it is very similar to chlorophyll involved in making food for the plant but basically it gives a purplish or olive like color to green plant stuff,it is produced in veggies when over cooked or cooked when covers
What is the difference between chlorophyll and choloroplasts?
Chloroplast is the organelle inside the plant cell, it is what absorbs and transforms light into energy. Chlorophyll is the green pigment, it traps the light.
What pigments do Nannocloropsis oculata utilize to photosynthesize?
These algae utilize chlorophyll a in photosynthesis. There is a big difference between the species of this genus with other microalgae. Nannocloropsis algae have neither chlorophyll b nor chlorophyll c.
What is the difference between an albino plant and regular plant?
an albino plant doesnt contain chlorophyll and a regular plant does an albino plant doesnt contain chlorophyll and a regular plant does
Green pigment in plants that absorbs light energy?
Chlorophyll is the green pigment. There is a chlorophyll a and chlorophyll b that are found in green plants. The only difference between Chlorophyll a and b is in its structure. Chlorophyll a has a -CH3 group and b has a -CHO group instead. Also, Chlorophyll is anchored to thylakoid membranes located inside a chloroplast."Chlorophyll" is the green pigment that stores sun energy while the process is called "Photosynthesis"The green pigment that traps light energy from the sun is known as chlorophyll. It is found in plant cells and it uses this trapped energy in the process of photosynthesis.
What is the difference between algae and plants?
both contain chlorophyll11 but plants are differentiate between stem,roots & leaves and algae can not be differentiate between stems,roots ant leaves.
What is the relationship between photosynthesis and chlorophyll?
Chlorophyll is the pigment needed in order to undergo photosynthesis. Chlorophyll is what absorbs the light.
