why rhodophyta exhibit a red colour? (a) since most rhodophyta grow at great depth, the chlorophyll can only absorb light in the red area of spectrum. (b) the wavelength of light that are absorbed by chlorophyll are passed to phycoerythin (c) red pigment of rhodophyta absorbs all the light waves (d) the light reaching the greatest depth in water is in the blue- green region of the spectrum, is absorbed by phycoerythin.
Answers
Answer:
Red algae are red because of the presence of the pigment phycoerythrin; this pigment reflects red light and absorbs blue light.
Explanation:
Photosynthetic pigments of Rhodophyta are chlorophylls a and d. Red algae are red due to phycoerythrin. They contain the sulfated polysaccharide carrageenan in the amorphous sections of their cell walls, although red algae from the genus Porphyra contain porphyran.
step by step explanation
Earlier work has shown that chlorophyll a is the principal chlorophyll of red algae, and that chlorophyll b is absent, or present only in traces (4-7).
