Put the following events of the acid growth hypothesis in order.
1) Cell wall softens and expands.
2) Sugar enters the cell via proton cotransporters.
3) Protons are pumped out of the cell by H⁺- ATPases.
4) Positively charged ions enter the cell.
5) New cellulose microfibrils are produced to extend cell length.
6) Water enters the cell via osmosis, and the cell swells.

Question

Quizplus · Accepted Answer

The correct sequence according to the acid growth hypothesis starts with protons being pumped out of the cell, which leads to the entry of positively charged ions, followed by sugar entering through proton cotransporters. This osmotic change causes water to enter the cell, leading to cell swelling, wall softening, and expansion, and finally, new cellulose microfibrils are produced to extend the cell length.
