Current Question (ID: 12084)

Question:

An alga which can be employed as food for human beings:

Options:

1. Ulothrix
2. Chlorella
3. Spirogyra
4. Polysiphonia

Solution:

Chlorella is a genus of green algae that is often used as a food source for human beings due to its high nutritional value. Chlorella is rich in protein, vitamins, minerals, and other essential nutrients, making it a suitable candidate for human consumption. It is often consumed in the form of supplements, powders, or added to food products as a source of nutrition. Ulothrix, Spirogyra, and Polysiphonia are also genera of algae, but they are not commonly used as food for human beings. Ulothrix and Spirogyra are filamentous green algae commonly found in freshwater habitats, while Polysiphonia is a genus of red algae commonly found in marine environments. These algae may have ecological or industrial importance, but they are not typically consumed as food by humans.
