Answer 1

Answer:

ANSWER

Cell wall is dead and fully permeable. It cannot regulate the entry of solvent or solute molecules. This fact is established by the accumulation of water and mineral salts in the periplasmic space, which is the space between cell wall and cell membrane. If cell wall was semi or differentially permeable; mineral salts would not have accumulated in the periplasm.

so, the correct answer is 'Soil into periplasmic space of root hairs'
