The correct answer to the question is:
b. Trypanosoma cruzi
Trypanosoma cruzi is the organism among the options provided that has a cell wall. Cell walls are present in various organisms like plants, fungi, algae, and some bacteria. They provide structural support and protection to the cell, helping to maintain its shape and prevent it from bursting due to osmotic pressure.
In this case, Trypanosoma cruzi is a parasitic protozoan that causes Chagas disease in humans. It is classified as having a cell wall, distinguishing it from other options like Candida albicans, Enterobius vermicularis, and Entamoeba histolytica, which do not possess cell walls.
Understanding the presence or absence of a cell wall in different organisms is crucial as it plays a significant role in their structure, function, and classification within the biological kingdom.
