Unformatted text preview: Potato Cores Conclusion It is important for plant cells to always be immersed in solutions that are hypotonic in comparison to the inside of the cell. A solution is regarded hypotonic in comparison to a cell if it has less solute. If a solution has less solute, it also has a higher water potential than that of the cell. Therefore, more water flows into the plant cell from the extracellular fluid because water travels from areas of higher water potential to areas of lower water potential. Plant cells are able to survive in hypotonic solutions because they have cell walls that can apply pressure. This is also why animal cells burst in hypotonic solutions: they dont have cell walls to apply an opposing pressure. As water flows into the plant cell, the plasma membrane is being more and more pressed against the cell wall, leading to turgor pressure. The cell wall is a strong matrix of cellulose and other polysaccharides and proteins, and so instead of bursting, it applies pressure on the...
