The diagram shows the presence of a pathogen amongst RBCs in the peripheral blood smear of a patient. Even though the shape is very easy to identify, the structure highlighted in the circle should enable you to identify the pathogen easily. It is:
| 1. | Trypanosoma | 2. | Plasmodium |
| 3. | Schistosoma | 4. | Clonorchis |
Identify the organism shown in the figure and the function of the structures shown by arrow:
1. Paramoecium, trophic functions
2. Euglena, sexual reproduction
3. Paramoecium, osmoregulation
4. Euglena, photoreception
