Solution
The question pertains to the sources from which algin can be obtained. Algin is a natural polysaccharide that is primarily derived from algae.
Answer
Algin is primarily obtained from the brown algae (class Phaeophyceae), particularly from genera such as Macrocystis, Laminaria, and Ascophyllum. While some species of red algae (class Rhodophyceae) might contain alginate in smaller amounts, the primary source of algin lies in the Phaeophyceae.
Therefore, the correct answer to the question "Algin can be obtained from" is:
- Phaeophyceae & Rhodophyceae
However, it is important to note that the dominant source of algin is from Phaeophyceae, specifically the brown seaweeds.
