The different parts of the plants do different jobs.

Plants and trees have roots, they hold the plants in the soil.

Roots take water from the soil;
Water travels up the stem to the leaves;

Roots keep trees standing in the wind

There are different types of root:

This is a storage root:

Stems:
The stem grows up from the ground.

The stem carries water from the root to the leaves and flowers:

In the stem there are xylem and phloem:

The rings in a tree trunk show how many years it grow for:
