Why does a limp carrot placed in a glass of water become crisp again?
Select one:
a. Water moves out of the carrot cells by diffusion
b. Water moves out of the carrot cells by osmosis
c. Water moves into the carrot cells by diffusion
d. Water moves into the carrot cells by osmosis
not sure please help me.
I think it's B because water has to come out, and osmosis is more about the health of cells. (carrot cells)
Copied from Google.
If placed in fresh water, the carrot is saltier than the surrounding water, so the water moves into the carrot. This causes the carrot to stiffen if it was previously limp, or preserve its crispness if it was crisp before. This is why cut carrots and celery are often stored in fresh water.
The movement is by osmosis but that isn't from Google
So, it is by osmosis, but the water goes IN the carrot? I'll put D if so.
That's the way I read it.
Alright then.
To determine why a limp carrot placed in a glass of water becomes crisp again, we need to understand the process of osmosis. Osmosis is the movement of water from an area of lower solute concentration to an area of higher solute concentration through a semi-permeable membrane.
In this case, when a limp carrot is placed in a glass of water, the carrot cells are dehydrated, causing the carrot to lose its crispness. The higher solute concentration inside the carrot cells compared to the water outside the cells creates a concentration gradient that drives the movement of water.
To answer the question, we need to consider which of the options describes the movement of water across the carrot cells.
Option b. Water moves out of the carrot cells by osmosis is incorrect because osmosis involves water moving from an area of lower solute concentration to an area of higher solute concentration. The water will not move out of the carrot cells.
Option c. Water moves into the carrot cells by diffusion is also incorrect. Diffusion is the movement of solute particles from an area of higher concentration to an area of lower concentration. However, in this case, we are specifically interested in the movement of water, not solute particles.
The correct answer is option d. Water moves into the carrot cells by osmosis. When the limp carrot is placed in a glass of water, the higher solute concentration inside the carrot cells causes water to move from the surrounding water into the cells, rehydrating them. This helps restore the crispness of the carrot.
Therefore, the process responsible for the crispness return in the limp carrot is osmosis.
