Which one of the following is true for the polymertrapping model of sugar diffusion in plant cells?
The principle of cellular compartmentalization and cell cycle explains that SNARE-mediated trafficking, Hayflick limit, P53 and cyclin regulation control proliferation. Hence Sucrose should be more concentrated in the mesophyll than in the intermediary... fits best because it aligns with membrane trafficking and cell cycle control, as documented in authoritative sources
Ref: Alberts et al., Molecular Biology of the Cell, 6th Edition, Chapter 10, Membrane Structure and Transport, discusses SNARE proteins, vesicle trafficking, ER, Golgi, endosome membranes and selective transport providing compartmentalization foundation.
