Question

Special carrier molecules in the cell membrane of the root hair carry the mineral ions across the cell membrane into the cell, against their concentration gradient and uses energy. This is calleddiffusionactive transportosmosispassive transport

Answer 1

Kinds of transport

There are two main types of transport:

-Passive transport: is down the concentration gradient and does not require energy. Here we can find

a) difussion: through the cell membrane and there is no protein involved.

b) osmosis: is the passage of water molecules through the cell membrane.

-Active transport: there's a use of energy implied and the molecule is transported against its concentration gradient.

Therefore, the correct answer to this question is active transport.
