|
|
Term
|
Definition
| The nonliving portion of a plants vascular system that provides support and conveys xylem sap from the roots to the rest of the plant. Xylem is made up of vessel elements and or tracheids, water conducting cells. Primary xylem is derived from the procambium. Secondary xylem is derived from the vascular cambium in plans exhibiting secondary growth. |
|

Term
|
Definition
| A group of plants that lack xylem and phloem; a nonvascular plant. Bryophytes include mosses liverworts in hornworts. |
|
|
Term
|
Definition
| Consisting primarily of epidermal cells, dermal tissue covers the entire surface of the plant. Guard cells in a plant's epidermis control the opening and closing of little holes called stomates that allow the plant to exchange gases with its environment. |

Definition
| This tissue type makes up most of the plants body and contains three types of cells. |
|
|
Term
|
Definition
| The system of tubules inside a plant that carries nutrients around is made up of vascular tissue. Vascular Tissue consists of a water transport system called xylem and a sugar transport system called phloem. Vascular tissue also contains the vascular cambium, a tissue of cells that can divide to produce new cells for the xylem and phloem. |
