Question
1. Assume that the interior of an onion cell is 98% water molecules. The remaining 2% is composed of various dissolved particles.
The salt solution you applied to the slide is ________% water molecules and ______% salt particles.
2. Using the information in question 1, add an arrow to the picture you drew of the onion cells in saline
solution, showing the direction of water movement.
3. The process that occurred to the onion cells in salt solution was an example of which, diffusion or osmosis?
Explain your answer.
4. The onion cell membranes allowed water to enter and leave the cells freely, but did not allow salt particles to diffuse into the cells.
This an example of a _____________________permeable membrane.
5. A student performed the onion cell experiment using human blood cells. When the student placed the blood cells in salt water, they shriveled up and died.
When the student placed other blood cells in distilled water, they filled up, exploded, and died.
What cellular organelle present in onion cells, but not blood cells, prevented the leaf cells from shriveling or exploding during your experiment?
