Which photosynthetic pigment is found in all photosynthesizing organisms?

a. beta-carotene

b. chlorophyll a

c. chlorophyll b

d. xanthocyanin

Chlorophyll a

Explanation:

Chlorophyll is green pigment stored on chloroplast thylakoids where it participates in the process of photosynthesis as a light collector and photoelectric transformer.

There are five types of chlorophylls, but chlorophyll a is the main pigment of photosynthesis and is contained in all green plants that perform photosynthesis.

Chlorophyll has the ability of fluorescence, which means that the light it absorbs can be released again. Therefore, the solution of chlorophyll, observed in the tube in reflected light, is a deep red color.

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.
