Question

6.3 trypanosome parasites in blood (trypanosoma brucei) - the causative agent of african sleeping sickness in humans. nuclei, flagella, and kinetoplasts are visible on the specimens depicted in the micrograph. check your progress 2.1 describe the length and width of a trypanosome compared to a red blood cell. 2.2 are trypanosomes larger or smaller than euglena? 2.3 do trypanosomes possess chloroplasts? how do they obtain nutrients? 2.4 how are kinetoplastids similar to euglenoids?

Explanation:

2.1: Trypanosomes are generally longer and thinner than red - blood cells. Red blood cells are round and relatively small in diameter, while trypanosomes have an elongated, slender shape.
2.2: Trypanosomes are generally smaller than Euglena. Euglena are larger single - celled organisms with more complex internal structures in general compared to trypanosomes.
2.3: Trypanosomes do not possess chloroplasts. They are heterotrophic and obtain nutrients by living as parasites in the host's body, absorbing nutrients from the host's tissues and body fluids.
2.4: Kinetoplastids (trypanosomes are kinetoplastids) and euglenoids are both flagellated protists. They use flagella for locomotion.

Answer:

2.1: Trypanosomes are longer and thinner than red - blood cells.
2.2: Trypanosomes are smaller than Euglena.
2.3: No, they obtain nutrients as parasites from host tissues and fluids.
2.4: Both are flagellated protists.
