Final answer:
When a plant cell has a higher sugar concentration inside than outside, it is in a hypotonic environment, leading to water entering the cell through osmosis, causing the cell to become turgid but preventing lysis due to the rigid cell wall.
Step-by-step explanation:
Osmosis is the movement of water through a selectively permeable membrane from an area of higher concentration to an area of lower concentration of water. In the case of a plant cell with a higher concentration of sugar particles inside than outside, water will move into the cell by osmosis. This is because the external environment is considered to be hypotonic with respect to the cell's interior, which means the concentration of solutes is lower outside the cell and the concentration of water is higher. As osmosis occurs, water will enter the plant cell in an attempt to balance the solute concentrations on both sides of the cell membrane, leading to the cell becoming turgid. However, due to the rigid cell wall, plant cells are more resistant to bursting than animal cells, a condition which would be caused by excessive water intake, known in plants as lysis.
