Question

Match the physical characteristics of the organisms to their purpose.

1) pili
2) cilia
3) flagella
4) pseudopods
5) thin, hairlike structures used for locomotion
6) long, tail-like structure used for locomotion
7) feetlike projections to capture a potential prey
8) used to hold onto rocks

Answer 1

Pili, cilia, flagella, and pseudopods serve different purposes in organisms.

Step-by-step explanation:

The physical characteristics of certain organisms serve specific purposes:

1. Pili: Pili are filamentous appendages found on prokaryotic cells that aid in attachment to surfaces. They are also involved in the transfer of genetic material between cells.
2. Cilia: Cilia are hair-like structures found on the surface of cells that can be used for locomotion. They are shorter than flagella and may move entire cells or substances along the outer surface of the cell.
3. Flagella: Flagella are long, whip-like structures that extend from the plasma membrane and are used to move an entire cell. They may be singular or present in a few numbers.
4. Pseudopods: Pseudopods are cytoplasmic extensions used by some protists to attach the cell to a surface and move themselves forward.
