A matured mammalian cell without nucleus is – (1) Lymphocyte (2) Erythrocyte (3) Spermatozoan (4) Oocyte
by

1 Answer

Answer :

(2) Erythrocyte Explanation: Mammalian erythrocytes are unique among the vertebrates as they are nonnucleated cells in their mature form. These cells have nuclei during early phases of erythropoiesis, but extrude them during development as they mature in order to provide more space for hemoglobin. In mammals, erythrocytes also lose all other cellular organelles such as their mitochondria, Golgi apparatus and endoplasmic reticulum.
