When a potassium ion (K) moves from the soil into the vacuole of a cell on the surface of a root, it must pass through several c
Sindrei [870]

Answer:

C) primary cell wall --> plasma membrane --> cytoplasm --> tonoplast

Explanation:

When a potassium ion moves from the ground into a vacuole of a plant cell, it must pass through the different structures that are part of it.

First, the outermost layer of the cell is the cell wall. Plant cells may have a primary and a secondary wall, but the latter is not always present. The primary wall is always located outwards (and in the case of having a secondary wall, it will be located between the primary wall and the plasma membrane).

Then, inside the cell wall, we will find the plasma membrane (also called plasmalemma).

When crossing the membrane, the ion will be in the cytoplasm of the cell and will be directed towards the vacuole, which is surrounded by its membrane called tonoplast. The vacuole is an organelle that has no definite shape, although it is always surrounded by the tonoplast, and it contains different substances such as water and enzymes.
