In eukaryotic cells that possess a cell wall (e.g., plants and fungi), what is the primary function of the cell wall?
A
Regulate selective transport of ions and small molecules into and out of the cell
B
Package and sort proteins for secretion via vesicular trafficking
C
Generate ATP through oxidative phosphorylation
D
Provide structural support and protection, helping maintain cell shape and resist osmotic swelling
Verified step by step guidance1
Identify the main components and functions of the cell wall in eukaryotic cells such as plants and fungi. The cell wall is a rigid layer outside the plasma membrane.
Understand that the cell wall is primarily composed of polysaccharides like cellulose in plants and chitin in fungi, which contribute to its strength and rigidity.
Recognize that the cell wall's main role is to provide structural support, maintaining the shape of the cell and protecting it from mechanical stress.
Consider the role of the cell wall in resisting osmotic swelling by preventing excessive water intake that could cause the cell to burst.
Differentiate the cell wall's function from other cellular processes such as selective transport (which is mainly done by the plasma membrane), protein packaging (done by the Golgi apparatus), and ATP generation (done by mitochondria).
