The economic importance of the stems is for food and building materials.

Functions of the stem

Stems provide a support to the leaves and reproductive structures.

They are used to store foods.

Stems which are green in color produce foods just like the leaves.

Stem structures

The stem has phloem, xylem, and cambium internally.

Phloem the bark of the stem is used to carry the food downwards. Xylem the wood of the stem is used to carry water and minerals upwards.

Cambium is used to separate the phloem and xylem and is also used to produce new cells.
