Question

Leucocytes are colourless due to:

• A. Lack of water
• B. Lack of haemoglobin
• C. Presence of extra water
• D. Presence of haemoglobin

Answer 1

The correct option is B Lack of haemoglobin

Leucocytes or white blood corpuscles are without haemoglobin, and therefore, they are colourless.

Haemoglobin is a red coloured pigment which gives RBCs their characteristic red colour and enables them to transport respiratory gases by binding with them.
