Question

Opisthokonta includes animals and fungi, as well as protists. Describe the key feature of this phylum, and an example of how an organism in each kingdom uses this feature.

Short answer

The presence of the flagellum on the posterior end of cells is the prime feature of Opisthokonts. Some of the examples of the Opisthokonts are the choanoflagellates, sponges, and fungi spores.

Step-by-step solution

Step 1: Introduction

The single posterior flagellums, which can be witnessed easily in the flagellated cells of the group are calledOpisthokonts. The members of Opisthokonts, which are also protists comprise an animal like choanoflagellates.

Explanation

Opisthokonta comprises fungi and animals, as well as protists. The key characteristic of Opisthokonts is the presence of the flagellum at the posterior terminal of the cells. Some of the examples of organisms are:

1. Sponges in animals utilize the flagellum for filter feeding.

2.Choanoflagellates utilize the flagellum for filter feeding.

3. In animals, male gametes utilize the flagellum for locomotion.

4. In fungi spores utilize the flagellum for locomotion.
