Jaylee · Answer 1

Some essential minerals are taken into the symplast by active transport

Explanation:

The soil solution contains minerals and water. The water gets absorbed by the roots via the process of passive transport called osmosis through aquaporins but the ions are unable to pass through the passive transport and require energy in the form of ATP and thus is known as active transport.

As the absorption of the mineral is an active process, therefore, minerals are absorbed against their concentration gradient and as a result, the minerals can be accumulated in the roots in much higher concentration than the soil solution.

Thus, the selected option is the correct answer.
