Which of the following is wrongly matched ?

Options

A. Hemoglobin in RBC-mammals
B. Haemozoin - Plasmodium cytoplasm
C. Haemocyanin - prawn
D. Haemoglobin dissolved in blood - Pheretima

Explanation

To determine which of the following options is wrongly matched, we will analyze each option one by one:

1. **Hemoglobin in RBC (Mammals)**:
- Hemoglobin is indeed present in the red blood cells (RBCs) of mammals. It is responsible for transporting oxygen from the lungs to the body and returning carbon dioxide from the body to the lungs. This statement is correct.

2. **Hemozoin (Plasmodium)**:
- Hemozoin is a pigment produced by the malaria-causing Plasmodium species when it metabolizes hemoglobin from red blood cells. This statement is also correct.

3. **Haemocyanin (Prawn)**:
- Prawns have a blood-like fluid called hemolymph, which is colorless. However, haemocyanin, a blue respiratory pigment, is actually found in the blood of some mollusks and arthropods, including certain species of octopus and some crustaceans. This statement is misleading because while prawns do have haemocyanin, it is not the primary respiratory pigment in their hemolymph, which is typically colorless. Thus, this option is wrongly matched.

4. **Hemoglobin dissolves in blood plasma (Ferritin)**:
- Hemoglobin does dissolve in blood plasma, but it is primarily contained within red blood cells. Ferritin is a protein that stores iron in the body and is not directly related to the dissolution of hemoglobin in plasma. However, this statement does not indicate a mismatch in the context of hemoglobin being present in the blood.

Based on this analysis, the wrongly matched option is:

**Answer: Haemocyanin (Prawn)**
