What is difference between chlorophyll A and b?
The main difference between chlorophyll A and B is their role in photosynthesis; chlorophyll A is the principal pigment involved in the photosynthesis whereas chlorophyll B is the accessory pigment, collecting the energy in order to pass into chlorophyll A.
What regions in the visible spectrum are most strongly absorbed by chlorophyll A and b?
Absorption spectra of the chlorophyll a and b pigments in the visible light range, measured in a solvent. Both types barely absorb green light. Chlorophyll a absorbs violet and orange light the most. Chlorophyll b absorbs mostly blue and yellow light.
What is the main function of chlorophyll A and b?
Chlorophyll’s role is to absorb light for photosynthesis. There are two main types of chlorophyll: A and B. Chlorophyll A’s central role is as an electron donor in the electron transport chain. Chlorophyll B’s role is to give organisms the ability to absorb higher frequency blue light for use in photosynthesis.
How can you tell chlorophyll A and chlorophyll b apart?
Chlorophyll a is blue-green, chlorophyll b is yellow-green, carotene appears bright yellow, and xanthophyll is pale yellow-green.
How chlorophyll a and b and accessory pigments differ?
Accessory pigments have a slightly different molecular structure than chlorophyll a that facilitates absorption of different colors on the light spectrum. Chlorophyll b and c reflect varying shades of green light, which is why leaves and plants are not all the same shade of green.
Which range of wavelengths is reflected by chlorophyll a and b?
Chlorophyll a reflects green and yellow-green wavelengths. Accessory photosynthetic pigments, including chlorophyll b and beta-carotene, absorb energy that chlorophyll a does not absorb.
Do all plants have chlorophyll a and b?
All plants, algae, and cyanobacteria which photosynthesize contain chlorophyll “a”. A second kind of chlorophyll is chlorophyll “b”, which occurs only in “green algae” and in the plants.
