What do carrier molecules form by binding with ions on the outer side of the cell membrane along with specific types of proteins?

$A$ : Most minerals must enter the root by active absorption into the cytoplasm of epidermal cells.
$R$ : Minerals are present in the soil as charged particles.

Phosphorus and nitrogen ions are generally leached from the soil because they are usually in the form of:

For the uptake of ions in the second phase of absorption of minerals,the pathway followed is called

Essential ions are absorbed in different amounts by
