3 ORGANS that a typical plant consists of: |
ROOTS |
|
ROOT HAIRS |
Absorb water and Minerals. |
|
Roots help_______ a plant in place |
Anchor |
|
Roots: Root Aplical Meristem |
Region of dividing cells.Continuously adds new cells to the root. |
|
Trunk of tree and all branches = _______ |
STEMS |
|
Stems: Node |
Where a leaf attaches to a stem |
|
Stems: Internode |
region (inter)between two successive nodes. |
|
Stems: Axullary buds |
Above each node. Can grow into a new branch! |
|
Shoot apical meristem |
Region of dividing cells! Usually grow upwards If damaged, AXILLARY BUDS can take over. |
|
Leaves |
Where photosynthesis occurs |
|
Leaves: SESSILE |
If there's JUST A BLADE. NOT blade AND petiole |
|
Leaves: Simple |
Blade is one section |
|
Leaves - Compound: |
Blade divided up into sections` |
|
Leaves - Compound: ______or______ |
PINNATE or PALMATE |
|
Plant Tissue Systems: DERMAL |
DEFENDS exterior of all organs. |
|
Plant Tissue Systems: VASCULAR |
Provides support & nutrient/water transport throughout plant. |
|
Plant Tissue Systems - VASCULAR: XYLEM |
Transports WATER & DISSOLVED MINERALS |
|
Plant Tissue Systems - VASCULAR: PHLOEM |
Transports basically everything else thats not WATER & DISSOLVED MINERALS
NOO PHROBLEM!!:))) |
|
Plant Tissue Systems: GROUND |
more like... GRIND TISSUE SYSTEM!!!!
BULK OF THE PLANT fills space b/w epidermis and vascular tissue.
Photosynthesis, water storage, stem storage, support. |
|
2 Main Groups of Flowering Plants |
MONOcots & DIcots |
|
Plant Growth is... |
...INDETERMINATE |
|
Plant Growth - ANNUALS |
Complete life cycle in 1 growing season (annually) |
|
Plant Growth - BIENNIALS |
require TWO growing seasons to complete their life cycle |
|
Plant Growth - PERENNIALS |
Can live and grow for many years producing many crops of seeds. |
|
Meristems & Growth |
Meristems/cambria = Regions of tissue in plants that can divide indefinetly. |
|
Apical Meristems |
Grow UP. Primary (1degree) growth. |
|
Lateral Meristems |
GROW SIDEWAYS. Secondary (2degrees) growth. |
|
Primary Growth in Roots |
Cells divide, enlarge, then can divide again. |
|
Primary growth in SHOOTS |
Cells divide, enlarge, then can divide again. DEVIL w/ HIS ARMS UP!!! |
|
Secondary Growth Occurs in_______ |
WOODY PLANT PARTS |
|
Vascular Cambian |
Produces 2degrees tylem (WOOD) towards the inside and 2degreesphloem (INNER BARK) towards the outside. |
|
Cork Cambian |
Produces cork (BARK) towards outside. Replaces epidermis in woody plants. |
|
DENDROCHRONOLOGY |
Analyzing ring growth patterns.
age
Rings wider in favorable weather conditions and vice versa. |
