Question

Write true or false:
Algae are classified based on their photosynthetic pigments.

Answer 1

Answer: True

• Algae are classified into three main groups primarily based on their photosynthetic pigments Chlorophyceae, Phaeophyceae, and Rhodophyceae.
• Chlorophyceae are usually green due to the dominance of pigments chlorophyll a and b.
• Phaeophyceae are usually brown due to the pigments chlorophyll a, c, carotenoids and xanthophylls.
• Rhodophyceae are usually red because of the predominance of the red pigment, r-phycoerythrin.
