Textbook Question
Parasitology is the study of parasitic:
a. A.viruses
b. Prokaryotes
c. Fungi
d. Eukaryotes
Verified step by step guidance1
Understand the definition of parasitology: it is the branch of microbiology that studies parasites and their interactions with host organisms.
Recall that parasites are organisms that live on or inside another organism (the host) and benefit at the host's expense.
Identify the types of organisms that are typically considered parasites in parasitology. These are usually eukaryotic organisms such as protozoa and helminths.
Review the options given: viruses (a), prokaryotes (b), fungi (c), and eukaryotes (d).
Since parasites studied in parasitology are eukaryotic organisms, the correct completion of the sentence is 'eukaryotes'.

Definition of Parasitology
Parasitology is the branch of biology that studies parasites, which are organisms that live on or inside a host organism and derive nutrients at the host's expense. It focuses on the biology, life cycle, and interactions of these parasitic organisms with their hosts.

Types of Parasites
Parasites can be prokaryotic or eukaryotic, but most parasitology studies focus on eukaryotic parasites such as protozoa and helminths. Viruses and fungi are generally not classified as parasites in parasitology, as viruses are acellular and fungi have different ecological roles.

Eukaryotes as Parasites
Eukaryotic parasites include protozoans and multicellular helminths, which have complex cellular structures with a nucleus. These organisms are the primary focus of parasitology because they cause many parasitic diseases in humans and animals.
