In plants root hair cells use the process of active transport to take in minerals.
Root hair cells are very long and have a very large total surface area which
allows it to absorb as much water as possible When it comes to absorbing
minerals there is usually more minerals in the root hair cell than in the soil
surrounding it, therefore the cell uses active transport to absorb as much
minerals as possible.
Water flow through plants
Xylem tubes take water up through the plant; it is made of dead cells. The
process of transpiration carries the water. Transpiration is caused by
evaporation and diffusion, so as water leaves the plant through the leaves
it will leave a gap which will then be filled by the water below, therefore
creating a running transpiration stream, so as water is lost ist is constantly
Phloem tubes carry food through the plant. They transport food substances
such as sugars and proteins. The food can travel in both directions.
