Plants??

Was it a standalone question, or was it in paragraph format. If the latter, I think everything you need to know would be in there somewhere.
THis was probably like a hypertonic/hypotonic problem, something that you should know very well, but plants in general are not on the MCAT, stuff like photosynthesis, plant anatomy you don't really need to know... but 😎 I know that stuff really well since my bio prof was a botanist and loved those topics 😀
It was a standalone question. If you place lettuce in deionized water, why does it still remain crispy? Ans: b/c the cells swell up with H2O.
Water movement in general moves from lower concentration of solvent to a higher concentration of solvent. Assuming that water in and of itself is generally considered a solvent, we notice that deionized water has less solute and more solvent.
Since the plant is originally not hydrated, it has more solute and less solvent. Therefore the water would want to move into the plant making it more crispy. Therefore the cells would take in the H2O.
If the cells didn't take in the H20 the plant cells would kind of wither away.
At least, that's how I see it.
