NEET BIOLOGY

Detailed explanation-1: -Spirulina (Arthrospira) belongs to the group of oxygenic photosynthetic bacteria and are filamentous, nonheterocystous cyanobacteria commonly found in tropical and subtropical regions. This alga is known as “superfood” of nature because its nutrient profile is more potent than any other food, plant, grain or herb.

Detailed explanation-2: -So the correct option is ‘spirulina’.

Detailed explanation-3: -In human nutrition, Arthrospira is mainly used for its high protein quality and concentration which can reach 60%–71% of the dry matter (Spolaore et al., 2006). The lack of cellulose in the cell wall of Arthrospira facilitates digestion (Karkos et al., 2008) of this food as compared to microalgae or macroalgae.

Detailed explanation-4: -Arthrospira platensis (AP) is a species of cyanobacterial phylum. Cyanobacteria typically carry out oxygenic photosynthesis with water as an electron donor and use carbon dioxide as a carbon source.

Detailed explanation-5: -Spirulina is a nutrient-dense cyanobacterium which is composed of protein, carbohydrates, vitamins, minerals, essential fatty acids, antioxidants and pigments including chlorophyll A and Phycocyanin.
