Metabolic Function/Storing Sugars
Pith/Vascular Rays/Cortex
Primary Growth
Apical meristem
Lateral Growth
Lateral meristem
3 Parts of Stems and Roots
Epidermis, Ground, Vascular (Xylem/Phloem)
Deciduous
Plant structures that fall off naturally at the end of a growing period.
Perennial Plants
Grow for more than two years
Cork
Produced by the cork cambium
What tree does most cork come from?
Cork Oak (Quercus suber)
4 Root Functions
- Anchorage
- Absorption
- Conduction
- Storage
3 Things Roots Have?
- Root cap to protect apical meristem
- No nodes
- Root hairs to absorb water
Where to roots branch from?
Grows from inside, not axillary buds
Cell Walls
Polysacrides
Plasma Membrane
Lipids and Proteins
Semi-permeable Membrane
Mitochondria
Makes product of chloroplast into usable energy
Vacuole
Empty space in cell (water)
Nucleus
Controls cell and holds DNA/chromosomes
Xylem Cells
Move water from roots to leaves and create wood
Vascular Cambian
Meristimatic tissue that produces xylem to the inside and phloem to the outside
Phloem Cells
Move sugars from leaves to roots
Spring Wood
Lighter rings, larger cells
Summer Wood
Darker rings, smaller cells
Bark
Everything outside the cork cambium
Lenticels
Perforations on the stem that allow for gas exchange
Meristematic
Undifferentiated Cells
Branches
Has meristematic tissue
Binomial System of Nomenclature
The system we use to organize all living things
Who created binomial nomenclature
Carl Linnaeus (Species Plantarum, 1753)
Alternate names for plant species
Specific epithet
Plant Communities
As assemblage of populations living in the same area
Anthropogenic Community
Human Disturbance
Biodiversity Hot Spots
Floristic Provinces
Mediterranean Climate
Mild, wet winters and warm, dry summers
Orographic Effect
Moist marine air cause precipitation on the western slopes
Rain Shadow
Climate is drier of the lee slopes rather than the windward
Thorn
Modified Branch
Sessile
No Periole
Stipule
Small leaves attached below petioles
Prickle
Epidermal growth
Spine
Modified Leaf
3 Leaf Functions
- Photosynthesis
- Transpiration
- Storage
Stomata
Oxygen and water leave
Inflorescence
A cluster of flowers in a specific arrangement
Angiosperms
Produce Flowers
3 Flower Functions
- Communicate with others
- Smell to attract animals
- Nectar
Pistillate Flowers
Female flower
Staminate
Male flower
Monoecious
Male and female on one plant but in different places
Dioecious
Different plants have different male and female parts
3 Parts of an Estuary
- Freshwater
- Saltwater
- Protected
Brackish
Salt and Fresh water mix
Salt Water Marsh
- Upper margin of estuary
- Few and small
- Mostly in Bay Area
Halophitic
Salt Tolerant Plants
Zonation
Haha
Anaerobic
Lacking O2
Aerenchyma Tissue
Allows for nutrients to go from roots to leaves
Halophytes
Concentrate salt in their tissue
Salt-excreters
Salt water on leaves
Hummocks
Small stabilized dunes
Blowouts
When a stabilized dune returns to being an active dune
Lignotubers
Plants can re-sprout from this after fire
Fire Cycle
10-50 year
Obligate Seeders
Haha
Forbs
Non-grassy herbaceous plants
Perennial bunch grass
Pre-colonial grasses (native)
Keystone Species
Important Species
2 Parts of a Fig
- Syconium
2. Ostiole
