Trypanosome and Plasmodium are both found in blood. How do they differ in their locations relative to red blood cells?
To write:
The difference in the locations of Trypanosoma and Plasmodium relative to red blood cells.
Introduction:
Trypanosoma is a monophyletic group of unicellular parasitic flagellate protozoa. It is a part of phylum Sarcomastigophora. Plasmodium is a group of unicellular eukaryotes that are obligate parasites of vertebrates and insects and it injects during a blood meal. It is a part of the phylum Apicomplexa.
Explanation of Solution
Trypanosoma and Plasmodium both are found in the blood. Trypanosoma lives in the blood plasma or lymph node fluid. Trypanosoma is an extracellular parasite that causes sleeping sickness and other chronic infections. It occurs in two main niches, early in infection, they populate the blood and later they breach the blood-brain barrier.
Plasmodium lives inside the red blood cells. Plasmodium involves development in the blood-feeding insect host which injects parasite into the vertebrate host during a blood meal. Parasites grow within the tissue body of the vertebrate, before entering the bloodstream to infect the red blood cells. It causes malarial infection.
Thus, Trypanosoma is found in the plasma or lymph node of the blood while Plasmodium is found inside the red blood cells of the blood.

- magine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different.
