Why are leucocytes classified as granulocytes and agranulocytes? Name each cell and mention its functions. White blood corpuscles or Leucocytes:(ii) Biofortification may help in removing hidden hunger. How?

Answer»

Solution :Based on the presence of granules in the cytoplasm of leucocytes it is classified into two categories. (ii) Agranulocytes. (1) Granulocytes: They contain granules in their cytoplasm. Their nucleus is irregular or lobed. They are classified into three types.
(a) Neutrophils
(b) Eosinophils and
(c) Basophils
(a) Neutrophils: Their numbers are increased during infection and inflammation.
(b) Eosinophils: Their number increases during conditions of allergy and parasitic infections. It also brings about detoxification of toxins.
(c) Basophils: They RELEASE chemicals during the process of inflammation.
(ii) Agranulocytes: Granules are not found in the cytoplasm of these cells. The agranulocytes are of two types: (a) Lymphocytes (b) Monocytes
(a) Lymphocytes: They produce antibodies during bacterial and viral infections.
(b) Monocytes: They are phagocytic and can engulf bacteria.
Biofortification is the SCIENTIFIC process of developing CROP plants enriched with high levels of desirable nutrients like vitamins, proteins and minerals. EG.
1. Protina, Shakti and Rathna are lysine rich maize hybrids
2. Atlas 66, a protein rich wheat variety.
3. Iron rich fortified rice variety.
4. Vitamin A enriched carrots, pumpkin and spinach.
By this way, Biofortification may help in REMOVING hidden hunger.
