Answer:
<u>Cilia</u>
Explanation:
Cilia and flagellum are made up of microtubules.
Cytoskeletal filaments are structures which allow movement. In cilia and flagella, the cytoskeletal filaments are present in the form of microtubules and the primary work of these structures is to facilitate in movement.
Cilia is also present in mammals to facilitate the movement of fluids in cells.
Structurally, there is no difference between cilia and flagella. The only difference between cilia and flagella is in their lengths.

Answer:
This question appears incomplete but The correct option is the last option
Explanation:
Cell membranes are made up of a lipid/phospholipid bilayer in which each layer consists of an hydrophilic head (water loving) and a hydrophobic tail (water fearing). The hydrophobic tail of each layer is oriented inward and the hydrophilic heads are oriented outward so the cell can interact with water molecules inside (the cytoplasm) and outside the cell environment. This orientation forms a critical part of the function of the cell membrane that makes it a selectively permeable barrier that regulates what goes in and out of the cell.
