Question

For each required organism be prepared name the structure used for motility, if any, and name their phylum (ie. Mastigophora, Ciliophora, Apicomplexa, Sarcodina)

Answer 1

Organisms have various structures for motility; Paramecium (phylum Ciliophora) uses cilia, Amoeba (phylum Sarcodina) uses pseudopodia, and Euglena (phylum Mastigophora) uses a flagellum. Lophotrochozoa may have a lophophore or trochophore larvae, while Opisthokonta, such as choanoflagellates, have a posterior flagellum.

Step-by-step explanation:

The phylum and structure used for motility can differ among various organisms. For instance, the organism Paramecium belongs to the phylum Ciliophora and uses hair-like appendages, known as cilia, for locomotion. The Amoeba is part of the phylum Sarcodina and utilizes lobe-like pseudopodia for movement. Lastly, the Euglena, belonging to the phylum Mastigophora, propels itself using a whip-like structure called a flagellum.

It's important to note that different organisms, such as those in the superphylum Lophotrochozoa, might have additional structures like the lophophore or trochophore larvae. Moreover, bacterial motility often requires the presence of a specific cellular structure such as flagella. In broader terms, choanoflagellates, under the phylum Opisthokonta, use a single posterior flagellum for movement, which is believed to mirror the common ancestor of sponges and potentially all animals.
