Select the correct statements out of (a - d)
(a) Single celled Spirulina can produce large quantities of food rich in protein, minerals and vitamins
(b) Body weight-wise the microorganism Methyliphilus methylotrophus produces several times more protein than a cow per day
(c) Button Mushroom is a rich source of vitamin C
(d) A rice variety has been developed which is very rich in calcium

  1. c and d

  2. a, c and d

  3. b, c and d

  4. a and b.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Statement (a) is correct as Spirulina is a protein-rich single-cell protein. Statement (b) is correct because Methylophilus methylotrophus has a high biomass production rate due to its rapid growth. Statement (c) is incorrect as mushrooms are not significant sources of vitamin C, and (d) is incorrect in this context.

Among the following which one is the richest source of proteins

  1. Wheat (Triticum vulgare)

  2. Rice (Oryza sativa)

  3. Gram (Cicer arietinum)

  4. Ground nut (Arachis hypogea)

  3. Beta vulgaris

  4. Rhizobium leguminosarum
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The chickpea (Cicer arietinum) is a legume of the family Fabaceae, subfamily Faboideae. It is also known as gram or Bengal gram, garbanzo or garbanzo bean and sometimes known as Egyptian pea, ceci, cece or chana. Its seeds are high in protein. Chickpeas are a nutrient-dense food, providing rich content of protein, dietary fibre, folate, and certain dietary minerals such as iron and phosphorus. Thiamin, vitamin B6, magnesium and zinc contents are moderate. Chickpeas have a Protein Digestibility Corrected Amino Acid Score of about 76 percent, which is higher than fruits, vegetables, many other legumes, and cereals. So, major source of protein is Cicer arietinum compared to Oryza sativa (rice), Beta vulgaris (beet root) and Rhizobium (bacteria). 
Thus, the correct answer is option B.
