Red Algae is described as containing beta-carotene and protein, with beta-carotene providing antioxidant and anti-aging benefits. What is this alga commonly called?

• A. Green Algae
• B. Blue-Green Algae
• C. Red Algae
• D. Brown Algae

Answer: (C)

Colors in algae come from their pigments, which helps identify their group. Red algae get their name from the pigment phycoerythrin that gives them a reddish hue, and they also carry carotenoids like beta-carotene that offer antioxidant benefits. The description mentions beta-carotene and antioxidant/anti-aging effects, which fits this red-algae profile best. Green algae are predominantly green due to chlorophyll, brown algae have fucoxanthin giving a brown color, and blue-green algae are cyanobacteria with different pigment patterns. So, the alga described is commonly called Red Algae.
