1. Active Transport
Roots can absorb other minerals ions dissolved in soil even if their concentration is higher in the plant than in the soil water.
Absorbing particles against a concentration gradient called active transport.
The energy needed for this process comes from respiration.

2. Active transport
To movement of substances against a concentration gradient and/or across a cell membrane
The process uses energy

7. Rate of active transport depends on the rate of respiration
Rate of respiration

8. Key Points
Involved in the transport of minerals, because there are more minerals in the plan then in the soil this happens against the concentration gradient (the opposite of osmosis)
This then means energy is required, this comes from respiration.
