Propagation roots develop from the stem that is cut and soaked in water.

Woody stems can be grouped into vines, shrubs and trees.

It is the SKIN where you can find ROOT HAIRS or tiny roots.

TAPROOT SYSTEM is a single big root with smaller roots growing from it. They sometimes are used as food storage, like in carrots, radish, turnips, etc.

The two types of roots are fibrous roots and the taproot system.

Herbaceous stems are usually green and do not develop woody tissues. These soft stems produce plants of limited sizes called herbs.

Climbing roots are vine roots that twine around supports.

Specialized roots do not penetrate deep into the soil but instead grow in the different parts of the plant.

The cortex is the outer layer of the root or stem that is responsible for moving water and dissolved minerals into the center of the root and for food storage.

The xylem are the tiny tubes that carry water and minerals up into the plant.

Fibrous roots are generally easy to uproot because they are are fine and spread instead of growing deep in the soil.

Plants with woody stems can reach great heights and can live for more than a year.

Brace roots or prop roots grow from the nodes of plants.

The two types of stems are herbaceous stems and woody stems.

Adventitious roots grow from the stem of leaves

The stem is the largest part of the plant.
