Why are proteins synthesised from Spirulina called single-cell proteins?
Why are proteins synthesised from Spirulina called single-cell proteins?

Solution: Single called protein is a protein-rich meal manufactured by microorganisms (SCP) Spirulina is a type of bacteria that has a lot of protein. Since bacteria proliferate at such a rapid rate, it provides a speedy method of protein production. As a result, it provides a high-protein diet for humans.

Therefore, a large amount of protein is produced in the single cell of spirulina within a short span which is rich in protein.
