Primary Root: This is the first root that comes from the seed and is the biggest.

Secondary Root: Similar to primary root although smaller and run sideways

Taproot system: Where Primary roots are the main roots. Secondary roots are rare or are not that common.

Fibrous Roots System: Where Primary roots systems are gone or "rotted away" and are replaced by the adventitious roots.

Runners

2014-12-04 20:16:17 UTC

Offshoots that are produced from a plant when the flowers are cut off from the plant. These offshoots have tiny roots which can be placed in the ground and can grow up into mature plants. Examples of plants that use runners are strawberries.

Pericycle: the thin layer coating the vascular cylinder

Annual: a description of a plants life cycle, from beginning to end

Perennial: plants that reproduce constantly every year

Cork Cambium: formed by the growth of the pericycle in plants over the age of two

Heartwood

Heartwood is the center of a stem. It does not transport minerals or water. It is more used as a type of support.

Sapwood

2014-12-04 20:17:43 UTC

The second layer of wood closet to the center of the tree. Sapwood carries minerals that are dissolved and water throughout the tree.

part of the pariderm that forms the outermost layer of the cork cambium

Adventitious roots

2014-12-04 20:18:11 UTC

Adventitious roots are roots that develop from a part of a plant other than the root.

Bark

2014-12-04 20:18:45 UTC

The outer covering of a tree. It is called a periderm as it replaces the epidermis (the outer cell layer).

Sap

2014-12-04 20:19:19 UTC

The "blood" of the tree. It is the fluid inside any plant.

Root cap

2014-12-04 20:19:48 UTC

A root cap is a loose mass of cells that form a protective cover for the apical meristems of most root tips.

Tubers

2014-12-04 20:20:43 UTC

Underground stems that are thick. These plant parts are specialized for keeping carbohydrates for the plant and participate in asexual reproduction.

Annual ring

2014-12-04 20:20:48 UTC

Annual rings are produced to show the yearly growth of a particular plant. The most common example can be seen in trees where a distinct ring is formed for every year of growth.

Root hairs

2014-12-04 20:22:26 UTC

Root hairs are microscopic extensions of epidermal cells near the tip of a root.

Root hairs help with absorption of water and minerals.

herbaceous

jacksonfrezell — 2014-12-04 20:25:05 UTC

a plant which does not develope bark

woody

jacksonfrezell — 2014-12-04 20:26:06 UTC

a plant which developes a periderm layer known as bark

Endodermis

2014-12-04 20:26:17 UTC

The endodermis is a layer of rectangular cells that surround the vascular cylinder
