Which type of algae is described as seaweed rich in vitamin C and magnesium?

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

Answer: (A)

Green algae carry the green pigment that signals chlorophyll, and chlorophyll contains magnesium, so these algae tend to be rich in magnesium. They are also noted for carrying notable amounts of vitamin C compared with other seaweed groups. That combination—magnesium linked to the green pigment and higher vitamin C content—fits the description of seaweed rich in vitamin C and magnesium. Brown algae typically emphasize minerals like iodine and alginates, red algae are known for carrageenan, and blue-green algae (cyanobacteria) are not true seaweeds and have a different nutrient focus, so they don’t match this description as well.
