what molecules are responsible for the color of green, red, yellow and brown algae?
Homework Answers
Ans.- Green algae have chloroplasts that contains chlorophyll a and chlorophyll b molecule that gives green color to this algae.
Red algae are red in color because of the presence of pigment Phycoerythrin. This pigment reflects red light and absorb blue light.
Yellow algae contains chloroplast that do not contain fucoxanthin, that are responsible for their lighter color. Carotenoids present in yellow algae are responsible for their color.
Brown algae contains green pigments (chlorophyll a and chlorophyll c) and the brown fucoxanthin. The brown color of these algae is because of the dominance of the xanthophyll pigment fucoxanthin, which mask the other pigments present in these algae like chlorophyll a , chlorophyll c, beta carotene and other xanthophylls.

Plain M&M's come in 6 different colors (Blue, Orange, Green, Yellow, Red, Brown) and are produced at two different plants. M&M's that come from a plant in Tennessee are supposed to have the following distribution of colors: 20.7% Blue; 20.5% Orange; 19.8% Green; 13.5% Yellow; 13.1% Red and 12.4% Brown. Quality control at the plant is concerned the machine is not working correctly and that it is producing a different distribution of colors. They take a random sample of 940...
