Eye spot granules of Euglena are formed of

• A. Fucoxanthin
• B. Astaxanthin
• C. $\alpha$-carotens
• D. $\beta$-carotene.

Answer 1

The correct option is B Astaxanthin

• The eyespot of euglena (also known as the rudimentary eye) is an organelle present in euglena which contains astaxanthin which gives a red color to the eyespot.
• This red color is sufficiently intense enough to give red color to the water in the abundant presence of euglena.
• This pigment is used to protect the chloroplast from excessive light.
• The correct answer is B.
