The cytoskeleton
A) includes flagella.
B) is fully present in prokaryotes.
C) moves organelles within cells.
D) is composed of polymers of nucleotides.
E) surrounds cells like cell walls.

Question

Quizplus · Accepted Answer

The cytoskeleton is responsible for the movement of organelles and other substances within the cell. It is composed of microfilaments, intermediate filaments, and microtubules.

Answer: A, C
 Flagella are part of the cytoskeleton and are responsible for cell movement. The cytoskeleton also moves organelles within cells. However, it is not fully present in prokaryotes as they do not have the same complex structure as eukaryotic cells.

Answer: D, E
 The cytoskeleton is not composed of polymers of nucleotides as these form nucleic acids. It also does not surround cells like cell walls as the plasma membrane is responsible for that function.
