Why is osmosis important to the survival of a cell?
A
It regulates the movement of water into and out of the cell, maintaining proper cell volume and internal conditions.
B
It transports large molecules like starch across the cell membrane.
C
It allows the cell to produce energy directly from water molecules.
D
It enables the cell to synthesize proteins from amino acids.
Verified step by step guidance1
Understand the concept of osmosis: Osmosis is the passive movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
Recognize the importance of osmosis in maintaining cell homeostasis: Osmosis helps regulate the balance of water inside and outside the cell, ensuring the cell does not shrink (due to water loss) or burst (due to excessive water intake).
Eliminate incorrect options: Osmosis does not transport large molecules like starch, as it specifically involves water movement. It also does not directly produce energy or synthesize proteins, as these processes involve other cellular mechanisms.
Focus on the correct function: Osmosis is crucial for maintaining proper cell volume and internal conditions, which are essential for the survival and functionality of the cell.
Conclude that the correct answer is: 'It regulates the movement of water into and out of the cell, maintaining proper cell volume and internal conditions.'
