To distinguish: The characteristics of free-living members of Sarcodina, Mastigophora, and Ciliophora. Introduction: The microorganisms are found abundantly in nature. There are six major classes of microorganisms, namely bacteria, archaea, fungi , protozoa, algae, and viruses. Protozoa are parasitic organisms feed on other microbes. It is unicellular eukaryote and is regarded as one-celled animals.

Answer 1

Question

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

Expert Solution & Answer

Explanation of Solution

The Sarcodina, Mastigophora, and Ciliophora are free-living protozoans that derive nutrients from other organisms. The characteristic features of Sarcodina, Mastigophora, and Ciliophora are as follows:

Group	Distinguishing characteristics
Sarcodina	These organisms have the extensions called pseudopodia. These organisms have a clear ectoplasm and a granulated endoplasm. These organisms are nucleated (a single nucleus) and contain food vacuoles and contractile vacuoles.
Mastigophora	These organisms are flagellated. These organisms have a pellicle layer outside the cell membrane and have an indistinct mouth. These are nucleated photosynthetic organisms that possess chloroplast and an eyespot that is sensitive to light.
Ciliophora	These organisms possess cilia. These organisms have a pellicle layer outside the cell membrane with distinct oral groove leading to the gullet through the mouth. These organisms are nucleated (with macro and micronuclei) and contain food vacuoles and contractile vacuoles.
