Lab Practical Flashcards
Monocot
1 cotyledon, parallel leaves, scattered vascular bundles, fibrous root system
Dicot
2+ cotyledons, reticulate leaves, circular vascular bundles, taproot system
Collenchyma
structural support, edges of plant tissue, near epidermis
Leaf Primordia
early shoot, develops into bud
Apical meristem
undifferentiated cells, tips of roots and shoots
Axillary Buds
dormant embryonic shoot
Amyloplast
storage of starch granules, stained purple
Sclereids
thick cell walls, pear’s gritty texture
Lenticel
allow O2 to enter the plant, allows for gas exchange in loose tissue, stimluates growth
Pine (Gym) Transverse
vertical thin rp/vertical boxy tracheids
Oak (Ang) Transverse
vertical thin rp/vertical circular vessel elements/surrounded by smaller circular fibers
Pine (Gym) Radial
Long thin vertical trachieds/Horizontal thin rp
Oak (Ang) Radial
Long skinny vertical fibers, gapping vertical vessel, small circular horizontal rp
Pine (Gym) Tangential
Vertical wispy trachieds/small circular rp in between
Oak (Ang) Tangential
Long vertical fibers/large vessel whole/small circular rp in between fibers
Gymnosperms
tracheids, pit membrane, sieve cells, sieve pores
Angiosperms
vessel elements, sclerieds, fibers, phloem sieve tubes (members, plates, companion cells)
Phloem Sieve Tube
sieve tube members, sieve plate, “plunger”
Stomatal Guard Cells Open
Hydrated
Stomatal Guard Cells Closed
Dehydrated
Adaxial
top, palisades parenchyma
Abaxial
bottom, stomata, spongy parenchyma
Monocot Leaves
Adaxial bundle sheath extensions
Shade Leaf
thinner, less tightly packed
Sun Leaf
expensive, thicker, more tightly packed, burns more sugar
Hydrophyte
aerenchyma and fewer stomata, huge circular aerenchyma holding O2
Xerophyte
stomatalcrypts
Leaf Abscission Zone
cortex parenchyma cells that are affected are stained and are corked off, vascular tissue is unaffected until the cork tissue has made it fully across
Leaf Vein Networks
mesophyll (site of chloroplasts)
Root Anatomy
Region of Maturation, Region of Elongation, Region of Division, Root Cap
Root Hairs
Region of Maturation
Monocot Root
Central pith, xylem and phloem surrounding
Dicot Root
Central xylem, surrounding phloem
Pericycle
Lateral root origin
Casparian Strip
ring-like band that controls the movement of water and solutes into the vascular tissue
Root Nodules
symbiotic infection of bacteria, nitrogen-fixing bacteria, swelling of the appendage on the lateral root
Anet
Assimilation of Carbon (umol/m^2s)
E
Evapotranspiration (mol/m^2s)
gsw
stomatal conductance (mol/m^2s)
Fv/Fm
chlorophyll fluorescence
LI-6800
Measures CO2/H20
IRGA
Infrared Gas Analyzer, two calibrated chambers, measuring difference in photosynthetic rate, matching occurs, drift happens, latch closes
Thermocouple
Two metals have a difference in temperature, which triggers a voltage that can be quantified
Driving Force (pressure)
P + G + H
Conductance
flux/driving force
Xcs
(l x conductance)/ xylem area
Lcs
(l x conductance)/ leaf area
