How will auxin influence cell growth in the roots of these plant (1point).
a. The cell has more solute, so solvent moves from outside the cell to inside, causing the cell to swell.
b. The environment has more solute, so solvent moves from inside the cell to outside, causing the cell to shrink.
c. The environment has more solute, so solvent moves from outside the cell to inside, causing the cell to swell.
d.The environment has more solute, so solvent moves from outside the cell to inside, causing the cell to swell.
The cell has more solute, so solvent moves from inside the cell to outside, causing the cell to shrink.
The cell has more solute, so solvent moves from inside the cell to outside, causing the cell to shrink.

To determine how auxin influences cell growth in the roots, we need to understand the concept of solute concentration and solvent movement.
Auxin is a plant hormone that plays a crucial role in regulating plant growth and development. One way in which auxin influences cell growth is by affecting the movement of solvents, such as water, across the cell membrane.
Based on the given options, let's analyze each one to determine the correct answer:
a. The cell has more solute, so solvent moves from outside the cell to inside, causing the cell to swell.
In this scenario, the cell has a higher concentration of solute compared to its environment. According to the principle of osmosis, water molecules would move from an area of lower solute concentration (outside the cell) to an area of higher solute concentration (inside the cell). This would cause the cell to swell. However, this statement contradicts the fact that auxin influences cell growth by affecting solute and solvent movement, not by having a higher cell solute concentration.
b. The environment has more solute, so solvent moves from inside the cell to outside, causing the cell to shrink.
This statement suggests that the environment has a higher concentration of solute compared to the cell. According to osmosis, water molecules would move from an area of lower solute concentration (inside the cell) to an area of higher solute concentration (outside the cell). This would result in the cell losing water and shrinking. This option implies that auxin's influence leads to a decrease in cell size due to solvent movement.
c. The environment has more solute, so solvent moves from outside the cell to inside, causing the cell to swell.
This statement states that the environment has a higher concentration of solute compared to the cell. According to osmosis, water molecules would move from an area of lower solute concentration (outside the cell) to an area of higher solute concentration (inside the cell). This would result in the cell gaining water and swelling. This option suggests that auxin's influence leads to an increase in cell size due to solvent movement.
d. The environment has more solute, so solvent moves from outside the cell to inside, causing the cell to swell.
This option is identical to option c, suggesting that the environment has a higher concentration of solute compared to the cell. According to osmosis, water molecules would move from an area of lower solute concentration (outside the cell) to an area of higher solute concentration (inside the cell). This would result in the cell gaining water and swelling. This option also implies that auxin's influence leads to an increase in cell size due to solvent movement.
Based on the analysis, the correct answer is option d: The environment has more solute, so solvent moves from outside the cell to inside, causing the cell to swell.
