Osmosis

Using figure 1 and 2 above, describe what you think happened to the plant cells in each of the figure. What does it mean by hypertonic and hypotonic?

Figure 1:

When the solution is hypertonic, the solution will be of a higher concentration compared to the cell. Thus, the cell will shrink. However, when the solution is hypotonic, the solution will be of a lower concentration compared to the cell. Thus, the solution will enter the cell but because it has a cell wall, the cell will not burst.

Figure 2:

For the 1st picture in Figure 2, the arrows are the same size thus it shows a same amount of concentration from both sides and the same number of molecules are moving. For the 2nd picture in Figure 2, the higher arrow is smaller compared to the lower area. This shows that there is more solute going into the cell.

Summary

• List the factors that affect diffusion

This information is already posted before this but I'll just post it again:)

Factors:

Temperature

Size of the molecules

Steepness of the concentration gradient

Summary

• Describe the movement of molecules with respect to concentration gradient

The molecules will move from the area with a higher concentration gradient towards the area with a lower concentration gradient until they reach a state of equilibrium

Summary

• Define diffusion

Diffusion is the process whereby the molecules move from the region of higher concentration to a region of lower concentration
