The Numerous Short Hair-Like Projections That Move Things Across the Surface

Question

The numerous short hair-like projections that move things across the surface of cells are
A)microvilli.
B)flagella.
C)cilia.
D)microtubules.

Accepted Answer

Cilia are the short hair-like projections on the surface of cells that move things across the surface. Microvilli are also projections on the cell surface, but they are much smaller and do not have the same movement function. Flagella are longer whip-like structures that are used by some cells to move themselves. Microtubules are structures within the cell that form the cytoskeleton and are not involved in movement across the cell surface.
