Multiple Choice
In eukaryotic organisms that possess a cell wall (e.g., plants and fungi), what is the primary function of the cell wall?
A
Serve as the site of ATP production via oxidative phosphorylation
B
Provide mechanical support and protection, helping maintain cell shape and resist osmotic swelling
C
Store and replicate the cell’s genetic material during the cell cycle
D
Regulate selective transport of ions and small molecules into and out of the cell
Verified step by step guidance1
Identify the main components and functions of the cell wall in eukaryotic organisms such as plants and fungi. The cell wall is a rigid structure located outside the plasma membrane.
Recall that the cell wall is primarily composed of polysaccharides like cellulose in plants and chitin in fungi, which contribute to its strength and rigidity.
Understand that the cell wall's rigidity provides mechanical support, helping the cell maintain its shape even under varying environmental conditions.
Recognize that the cell wall also protects the cell from physical damage and prevents excessive water uptake by resisting osmotic swelling, which is crucial for cell survival.
Differentiate the cell wall's function from other cellular processes such as ATP production (which occurs in mitochondria), genetic material storage (in the nucleus), and selective transport (regulated by the plasma membrane).
