Question
Which of the following cell lacks a cytoskeleton?
- Prokaryotic
- Eukaryotic
- Plant cell
- None of these
Hint:
The cytoskeleton ensures a proper framework and organization of the cell.
The correct answer is: Prokaryotic
- Prokaryotic cells lack the cytoskeleton.
- The cytoskeleton is present in all forms of eukaryotic cells but it is absent in prokaryotic cells.
- This refers to a body of fibers made up of various types of protein that form a network and gives the cell, its shape, and structure. It holds the organelles in right place too.
- But in prokaryotes, there is an absence of membrane-bound organelles. The genetic material and other substances simply float in the cytoplasm due to no organization and thus, they lack a proper cytoskeleton.
The eukaryotes need a cytoskeleton for their proper functioning as a vast variety of organelles need to be held in an organized manner.
