Question

In which Supergroup would the Chagas parasite be placed?

1) Excavata
2) Amoebozoa
3) SAR
4) Rhizaria
5) Archaeplastida

Answer 1

The Chagas parasite, Trypanosoma cruzi, belongs to the supergroup Excavata, specifically under the subgroup Euglenozoa.

Step-by-step explanation:

The Supergroup of the Chagas Parasite

The parasite responsible for Chagas disease is classified within the supergroup Excavata. This supergroup is characterized by species that exhibit a variety of life forms, including heterotrophic predators, photosynthetic species, and parasites. Notable for their asymmetrical single-celled structure with an 'excavated' feeding groove, members of Excavata have various modifications to their mitochondria and may also possess chloroplasts acquired through secondary endosymbiosis from green algae.

Specifically, Trypanosoma cruzi, the causative agent of Chagas disease, falls under the subgroup Euglenozoa within Excavata, which includes a mix of free-living and parasitic species. The Chagas parasite is known for its significant impact on human health, particularly in Latin America where it is endemic and transmitted by the 'kissing bug'.

Answer 2

IN Excavata Supergroup would the Chagas parasite be placed. Therefore, the correct option is 1) Excavata.

Step-by-step explanation:

The Chagas parasite, scientifically known as Trypanosoma cruzi, belongs to the Supergroup Excavata. Excavata is a diverse group of single-celled organisms characterized by specific structural features, including a distinct feeding groove or excavated feeding apparatus. Trypanosoma cruzi, responsible for Chagas disease, falls under the phylum Euglenozoa within the Excavata supergroup.

Euglenozoa organisms typically possess a unique flagellum and undergo various life stages, often displaying both free-living and parasitic forms. Trypanosoma cruzi, transmitted through triatomine insect vectors, causes Chagas disease in humans and other mammals.

Understanding the taxonomic placement of this parasite within the Excavata supergroup aids in studying its evolutionary relationships and its distinct biological characteristics, crucial for developing effective treatments and control strategies for Chagas disease. Therefore, the correct option is 1) Excavata.
