Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which percentage would explain the net movement of water into a cell through the process of osmosis?
A
water was 90% inside the cell and 95% outside the cell
B
protein was 30% inside the cell and 35% outside the cell
C
water was 95% inside the cell and 90% outside the cell
D
water and protein was equal inside and outside the cell
Explanation: 

Detailed explanation-1: -Answer. the right answer is: the process of osmosis would explain the bet movement of water into the cell if the percentage of water was 90% inside the cell and 95% outside the cell.

Detailed explanation-2: -Osmosis may occur in either direction across the cell membrane. Which percentage would explains the net movement of water into a cell through the process of osmosis? Water was 90% inside the cell and 95% outside the cell.

Detailed explanation-3: -Comparing the concentration of solvent on both sides, we see that there is a higher concentration of solvent outside the cell than inside (90% vs 86%). As the concentration of solvent is higher outside, the direction of osmosis will be inwards as to relieve the concentration gradient and reach equilibrium.

Detailed explanation-4: -Water is the most abundant molecule in cells, accounting for 70% or more of total cell mass.

Detailed explanation-5: -Osmosis is the net movement of water molecules across a semi-permeable membrane, from an area of low solute (high water activity) concentration to higher solute concentration (lower water activity).
