Question

Choose the correct answer from the alternatives givens.
A mature mammalian erythrocyte characteristically has:

• A. a bibbed nucleus
• B. no nucleus
• C. numerous plastids
• D. two centrioles

Answer 1

The correct option is B no nucleus

In humans, mature red blood cells are flexible and oval biconcave disks. They lack a cell nucleus and most organelles, in order to accommodate maximum space for hemoglobin; they can be viewed as sacks of hemoglobin, with a plasma membrane as the sack. So the correct option is 'no nucleus'.
