What gives sperms motility​
Mandarinka [93]

Answer:

The tail of the sperm, the flagellum

Explanation:

We find cilia in the human body. They coat the epithelial cells of the upper respiratory tract and play a role in keeping dust particles, smog, and potentially harmful microorganisms from entering the lungs.

Their movements enable the movement of mucus or other substances across the surface of various epithelial cells. The cilia also cover parts of the male and female reproductive tract.  

Flagella are found in sperm, whose tail represents the flagellum in its structure. The body wall of the sponge, among others, contains cells with whips that create and maintain the flow of water through the body.

What makes nekton swimming abilities different from plankton and benthos
Nitella [24]

Answer:

The nektonic organisms are those marine organisms that are found in almost every depth. These can move freely from one place to another in the ocean body due to its ability to swim. For example, Turtles, sharks, Fishes, and dolphins.

The planktonic organisms are passive swimmers, as they can move along with the ocean currents and are mostly found in the upper portion of the ocean body. For example, Diatoms and Rotifers.

The benthos is the bottom-dwelling organisms that cannot swim. For example, Bivalves, Corals and Sponges.

The nektonic organisms are different from the planktons and the benthos because the nektons can easily swim. They are constructed with such body parts that allow them to swim and migrate from one region to another region within the ocean water body. Whereas the planktons and the benthos cannot migrate easily and are considered as sessile organisms.
