If we dropped a plant cell into a hypertonic solution, or highly salty water, what do we think the cell would look like after osmosis occurs?
Hydrophilic Head
In this photo, blue particles represent water. Assuming they are separated by a semi-permeable membrane, which way will the the blue particles flow over time due to osmosis?
They will flow from right to left until reaching dynamic equilibrium
They will flow from left to right until reaching dynamic equilibrium
They will not flow because water doesn't move through a semi-permeable membrane
Hydrophilic head
In this photo, red particles represent water. Assuming they are separated by a semi-permeable membrane, which way will the the red particles flow over time through osmosis?
They will flow from right to left until reaching dynamic equilibrium
hydrophobic tail
They will flow from left to right until reaching dynamic equilibrium
They will not flow because water doesn't move through a semi-permeable membrane
