Roots, Stems, and Leaves Plants differ in shape and size, but most have roots, leaves, and stems. Each part has its own job to do to help the plant survive.

What are roots and stems and why do plants have them?

Roots and Stems. Functions of Roots  Anchor the plant  Absorb water and nutrients from the soil and transports them to the stems and leaves  Store.
