Question from 2020 Bio paper

Question from 2020 paper
Q2 b)
Explain why animal cells may burst when placed in fresh water, but plant cells will not.

I’m really confused with the ‘E’ point how is the process occurring in grana/thylakoid relevant to the question, and how would I know to reference these process even though question doesn’t refer to grana/thaylakoid?

Kia ora,

Please ensure that this ‘E’ part hasn’t mistakenly slid into the part (b) from another part of the question. It is most likely the ‘E’ part of another section of the question and not part of (b).

Good luck!
