correction (i think): when a cell is placed in a hypertonic solution water moves out of the cell since solute concentration is higher outside while water concentration is higher inside the cell. therefore water moves out of the cell and the cell shrivels

What is the manner out of which cell wall lacking bacteria sustain turgor pressure?

Very helpful. Is it true that it's the gram negative bacteria that leaves behind the liposaccharides or endotoxins? If so, why is it that gram positive bacteria doesn't? Thanks.

he means a HYPOtonic solution. If it were HYPERtonic, the water would move outside the cell decreasing the pressure, which contradicts the point! Hypotonic has a higher solution inside, so water would move from low (outside) to high (inside), that would increase the Pressure inside, which the Cell wall resist. I had to recheck my notes and all because that part didn't seem right to me, but good video nonetheless :)

great , but I think there is something wrong , when a cell is placed in hypertonic solution that means there is less solute inside the cell and water will tend to move from inside to outside

Hes referring to the inner environment of the cell. Usually the terms "hyper-" and "hypotonic" are taught referring to the extracellular environment, but they can be used to refer to any environment relative to its surrounding environment.

Can you explain the part of the hypertonic solution ? I was sure it means that there are more solutes outside the cell. THANK YOU! and as always your videos are pretty amazing !!

no he definitely means hypertonic - more solute, in a hypotonic solution (less solute). Water flows into the hypertonic cell through osmosis
