Minerals absorbed by the roots travel up the xylem. How do they reach the parts where they are needed most ? Do all the parts of the plant get the same amount of the minerals ?

Explanation

### Step-by-Step Solution:

1. **Absorption of Minerals**: The process begins with the roots of the plant absorbing minerals from the soil. These minerals are essential for various physiological functions in the plant.

2. **Transport via Xylem**: Once absorbed, the minerals travel upwards through the xylem vessels. The xylem is responsible for transporting inorganic nutrients and water from the roots to the rest of the plant.

3. **Role of Transpiration Stream**: The movement of minerals through the xylem is primarily driven by the transpiration stream. As water evaporates from the leaves (transpiration), it creates a negative pressure that pulls water (and dissolved minerals) up through the xylem.
