Study Notes

Locomotion in Parasites

Some parasites use pseudopodia as a means of locomotion.

Reproductive System in Dioecious Parasites

In dioecious parasites, the reproductive system consists of separate sexes.

Characteristics of Flukes

The characteristic feature of flukes is the presence of an oral sucker.

Parasites with Two Hosts

Echinococcus multilocularis is a type of parasite that requires two hosts to complete its development.

Function of Oral Sucker in Flukes

The oral sucker in flukes is used for attachment and feeding.

Tissue-Affecting Parasites

Some parasites cause disease by affecting different animal tissues based on the host tissue.

Similarity between Parasites and Bacteria

A key similarity between parasites and bacteria is that they are both heterotrophs.

Heterotrophic Protists

The category of protists that are heterotrophs is the animal-like protists.

Function of Pseudopods in Sarcodines

Pseudopods in sarcodines are used for locomotion and feeding.

Binary Fission in Protists

Amoebas reproduce through binary fission.

Characteristics of Ciliates

Ciliates are distinguished from other animal-like protists by the presence of cilia.

Difference between Animal-Like and Plant-Like Protists

Animal-like protists are heterotrophs, while plant-like protists are autotrophs.

Difference between Tapeworms and Roundworms

Tapeworms are flat, segmented worms, while roundworms are cylindrical and unsegmented.

Food Absorption in Tapeworms

Tapeworms absorb food through their body surface.

Function of Proglottids in Tapeworms

Proglottids in tapeworms are segments that contain reproductive organs.

Function of Spicules in Roundworms

Spicules in roundworms serve as copulatory organs.

Whipworm

Trichuris trichiura is commonly known as the Whipworm.

Organism with Flagella

Giardia is an organism characterized by having long whip-like hairs called Flagella.

Brain-Eating Amoeba

Naegleria fowleri is a protozoan parasite that causes the disease known as 'Brain-eating amoeba'.

Intestinal and Bloodstream Parasites

Endoparasites live inside the intestines or bloodstreams of a host.

Waste Removal in Paramecium

The anal pore in Paramecium functions in removing wastes.

Characteristics of Flatworms and Roundworms

Platyhelminthes (flatworms) and Nematoda (roundworms) are both characterized by being bilaterally symmetrical.

Parasitic Relationship

The type of relationship between host and parasite in which one organism benefits while the other is harmed is defined as parasitism.
