Answer to Problem 1SRQ

Correct answer: Erythrocyte is an anuclear and biconcave disk-like cell. Therefore, option a. is correct.

Explanation of Solution

Reason for the correct answer:

Erythrocytes are commonly known as red blood cells. They are found in the blood and they get the name due to the presence of hemoglobin that gives them their characteristic red color. The red blood cells lack nucleus and are biconcave disk in shape when viewed under the microscope.

Option a. is given as “Erythrocyte”

Erythrocytes lack a nucleus and their shape is biconcave disk. Hence, option a. is correct.

Reasons for the incorrect answers:

Option b. is given as “Granulocyte”.

Granulocytes are leukocytes and contain a nucleus. Therefore, option b. is incorrect.

Option c. is given as “Leukocyte”.

Leukocytes are also known as white blood cells and contain a nucleus. Therefore, option c. is incorrect.

Option d. is given as “Thrombocyte”.

Thrombocytes contain a nucleus. Therefore, option d. is incorrect.

Hence, options b., c., and d. are incorrect.

Conclusion

Erythrocytes lack a nucleus and their shape is biconcave disk.
