|
Vascular Plants |
Contain xylem and phloem, have a root system and leaves or another way to carry out photosynthesis; these two systems must be connected in some way |
Ex: trees, flowers, etc. Almost all land-bound plants |
|
|
Lignin |
Provide support for vascular plants |
Base of plant Platform for growth |
|
|
Xylem |
Carry nutrients and water from roots through the plant |
Moves water for plant Essential for the life of a plant |
|
|
Phloem |
Cells that form tubes with streaming cytoplasm that carry nutrients throughout a plant (like sugar) |
Tubular substance Moves nutrients like sugar in the plant |
|
|
Tracheids |
A type of xylem cell that has thick cell walls |
Protective outer layer Agent of transportation |
|
|
Vessel Elements |
A type of xylem cell that has thin cell walls and is wider |
Wide area used for transportation Thin layer of protection |
|
|
Cohesion |
Ability to bond to water molecules through hydrogen bonds |
"Flows" together Bond made with liquid |
|
|
Adhesion |
The ability to bond to polar molecules |
Charged bonding Definition of something sticking |
|
|
Sieve Tubes |
Phloem cells that are arranged in a chain |
|
|
|
Endosperm |
Used to store nutrients in a plant |
Storage unit Acts as a plant's stomach |
|
|
Coytledons |
A seed leaf |
Sprouts from seed Aids in seed growth |
|
|
Apical Meristems |
Involved in the primary growth of the plant, supporting growth from the tips of the roots |
Aids in the initial growth of a plant Located on the root endings |
|
|
Seed Coat |
The outer layer of a seed used for protection |
Coating/Layer Waxy to protect |
|
|
Germination |
When a seed grows into a plant |
The process of growth Normally occurs from seeds |
|
|
Primary Growth |
Comes from the roots or stems of a plant, initial growth |
Starts from the bottom of the plant Beginning of plant's life |
|
|
Node |
Where plants sprout leaves |
An example is a branch on a tree The extremity of a plant |
|
|
Root Cap |
Used as protection for the tip of the root |
Conceals and protects At the end of a root |
|
|
Epidermis |
Outer layer of plant tissue |
Top layer External coating |
|
|
Cuticle |
Covers and protects the epidermis |
Protects the whole plant Outer most layer of the plant |
|
|
Vascular Tissue |
Contains the xylem and phloem in vascular plants and helps the carrying of water and nutrients |
Aids in the transportation of essential substance Only in vascular plants |
|
|
Ground Tissue |
The other tissues in a plant other than the vascular tissue and the epidermis, aids in the process of photosynthesis and stores food |
Assorted tissues in a plant Inner layers of tissue |
|
|
Secondary Growth |
Causes root growth in terms of making the roots stronger to provide support |
Strengthening stage of growth Supports roots |
|
|
Vascular Cambium |
A substance located between xylem and phloem in a plant's roots or stem |
Separates two major transport substances Located in central base |
|
|
Pericycle |
Thin layer of tissue outside of the phloem |
Protector of on transport system A type of plant tissue |
|
|
Plant Growth Regulators (PGRs) |
An organic solution, natural or artificial, that is added to a plant to aid it in a specific growth process |
Used to aid in the growth of a plant Can either be artificial or naturally manufactured |
|
|
Auxins |
A hormone that helps in the regulation of plant growth |
Keeps balance Aids plant growth |
|
|
Gibberllins |
A hormone that initiates growth of a plant |
Involved in beginning stages of plant life Natural sort of growth hormone |
|
|
Cytokinin |
A hormone that Aids in plant growth by moving through the plant with the assistance of xylem |
Helps plant growth by travelling throughout it Travels through xylem |
|
|
Abscisic Acid |
Prevents plant growth and causes leaves to fall from the plant |
Causes leaves to fall in the winter Restricts some plant growth |
|
|
Ethylene |
A natural hormone that aids in plant growth, is released from plants, especially fruit |
Natural gas Can help the ripening of other plants when the gas is realeased |
|
|
Tropism |
The movement of a plant towards an outside stimuli |
Moves toward something Faces a light/energy source |
|
|
Phototropism |
The movement of a plant to face the sun |
An example is sunflowers Changes the way a plant faces, in direction |
|
|
Gravitropism |
When a plant grows in terms of its response to gravity |
Can have positive or negative effects on growth Normally found with land plants |
|
|
Photoperiodism |
A plants response to a certain season or time of day |
Effects the bloom or sprouting of plants because of environment Can have different growing patterns for each time of year |
|
|
Phytochrome |
A pigment used by plants to detect light |
Utilized to gain energy Seek out energy/stimulus |
