Vedclass · Answer

(B) Thrombocytes,or blood platelets,are cell fragments produced from special cells in the bone marrow called megakaryocytes ($I, II, III$ are correct).They are essential for the process of blood coagulation or clotting ($V$ is correct).The normal count of platelets in a healthy human individual is $1,50,000$ to $3,50,000$ per $mm^3$. Therefore,statement $IV$ is incorrect because the range provided in the option is higher than the standard physiological range.Thus,the correct statements are $I, II, III,$ and $V$.
