Compared to those of humans, the erythrocytes in frog are
Options
- Awithout nucleus but with haemoglobin
- Bnucleated and with haemoglobin
- Cvery much smaller and fewer
- Dnucleated and without haemoglobin
Correct answer
D. nucleated and without haemoglobin
Step-by-step solution
Mature human erythrocytes (RBCs) are enucleated (lack a nucleus) to provide maximum space for haemoglobin, which is responsible for oxygen transport.
Frog erythrocytes are large, oval, biconvex, and possess a distinct nucleus.
Both human and frog erythrocytes contain the respiratory pigment haemoglobin.
Therefore, compared to human erythrocytes, frog erythrocytes are nucleated and contain haemoglobin.
