Answer:
Herbicide essentially replaces sugar with itself during uptake by plants.
Explanation:
Noting that the pH is decreased around the plant cells indicate that there is an acidic environment that exists, It also indicates that the cell wall had been perforated and the contents are being expelled or at the very least leaking.
The ability for the plant to break down and use sugar is vital for its survival. Most herbicides are in the form of glycophosphates and it moves along with the sugar in the plant that have been treated with herbicides through the transport vesicles, the xylem and phloem.
This causes an imbalance in the available sugars that are able to be taken up by the plant since much of it is replaced by the herbicide.
I believe that secretion into the tubular fluid occurs when the principle cells in the Proximal convoluted tubule secrete H+ into the urine.
Tubular secretion is the transfer of materials from peritubular capillaries to the renal tubular lumen; it is the opposite process of reabsorption. This secretion is caused mainly by active transport and passive diffusion.
