Plant morpho-anatomy Flashcards
General form or architecture of a plant, encompassing stem duration and branching pattern, development, or texture.
plant habit
non-woody plants
herb
a perennial herb with rootstock. Roots are never dying because they have a very developed rootstock.
geophyte
weak stemmed climber
vine
woody vine
liana
woody, with multiple stems from base, no main trunk
shrub
shrub that is woody just above ground
subshrub
woody with one main trunk
tree
Is Banana a tree?
no, lacks vascular cambium
Is bamboo a tree
no, tallest grass
is coconut a tree?
no, lacking secondary xylem
how long a plant lives
plant duration
differentiate annual, biennial, perennial duration
annual - less than or equal to 1 year
biennial - 1st year: germinate, grow; 2nd year - flowers and fruits then die
perennial - 3+ years do not die after bearing fruits, renew parts after each season
plant habitat
envi where a plant lives
terrestrial vs aquatic
terrestrial - land
aquatic - water
epiphyte vs xerophyte vs mesophyte
all are terrestrial:
★ Epiphyte
* growing on the surface of other plants
★ Xerophyte
* living in dry, hot or cold environments
★ Mesophyte
* living in moderate environments
differentiate submerged, floating and emergent
all are aquatic:
★ Submerge
* completely in the water
★ Floating
* on the water surface
★ Emergent
* normally see the leaves or flowers high above the water
structure, life cycle, ecophysiology
plant life form
annual plant in seed form during most unfavorable conditions. These plants must grow so fast, and the seeds will perpetuate their kind.
therophyte
with perennating buds (resting buds) just below the ground
cryptophyte
with perennating bud (resting bud) at or near the ground
hemicryptophyte
woody plants with perennating bud less than 2 meters above the ground
chamaephyte
woody plants with perennating buds greater than 2 meters above the ground
phanerophyte
plants that obtain moisture and nutrients from air and rain. They have lost their roots, and they are existing as leafless stem
aerophyte
what are primary plant body
plants that are not yet woody
universal model of plants
Arabidopsis thaliana
root vs shoot system
root - everything under ground
shoot - everything above ground
