Leaves
morphology and anatomy of other leaf types
succulent leaves
thick
fleshy
favors water conservation
mesophyll
very few airspaces
more transparent
photosynthesis occurs deeper
sclerophyllous foliage leaves
hardness
long lasting
resistant
thick cell walls
waxes
thick cuticles
leaves of conifers
sclerophylls
thick cuticle
thick walls
unpalatable chemicals
always simple
mostly perennial
year round
bud scales
protection
dormant shoot apical meristems
low temperatures
drying action of wind
small
rarely compound
petiole
short or non existent
spines
cacti
microscopic leaves
axillary buds
good source of water
too many spikes
closely packed fibers
tendrils
modified leaves
grow indefinitely
sense contact
contact
stops growing, though other side will continue
curl system
grow around objects
leaves with Kranz anatomy
C4 photosynthesis
lack
palisade parenchyma
spongy mesophyll
prominent
bundle sheaths
large chlorophyllous cells
arid enviroments
insect traps
habitat
low nitrates and ammonia
capable of photosynthesis sometimes
lamina
tubular rather than flat
watery digestive fluid
epidermis
absorptive rather than impermeable
external structure of foliage leaves
jobs
fungi deny
bacteria deny
epifoliar algae deny
not too delicous
not too great sails
grow cheaply
photosynthesis
carbon dioxide
light energy
carbohydrate
leaf blade
dorsal surface
large veins
ventral surface
soft
sessile leaf
close package
simple leaf
blade of one part
compound leaf
several parts
leaflets
concepts
"leaf"
spines
protection
tendrils
support
storage
fleshy leaves
nitrogen procurement
digestion
internal structure of foliage leaves
epidermis
flat
thin
large surface area
water loss
transpiration
problem if roots are dry
guard cells
stomata
water port
trichomes
hairy
stingy compounds
prevent rapid air movement
mesophyll
ground tissue
interior to epidermis
palisade parenchyma
photosynthesis
intercellular space
CO2 dissolves
large surface area
one layer thick
could be up to 3 or 4
spongy mesophyll
sometimes lacking
vascular tissue
midrib
lateral veins
minor veins
material exchange
primary xylem
upper
primary phloem
lower
bundle sheath
midvein
petiole
tiny but mighty
like cortex
leaf traces
ring, plate or other pattern
stipules
initation and development of leaves
basal angiosperms and eudicots
shoot apical stem
leaf production
leaf primordium
leaf protoderm
leaf ground meristem
connection to young bundles
thickness in growth
lamina
midrib
two small, thin wings
completed when 1 tenth the mature size
monocots
expansion of some shoot apical meristems
shoot apex enlarges
new stem tissue
initiates next leaf primordium
process repeats
hood like shape
sheathing leaf base
lamina
can become broad and expanded
grasses, lilies, star shaped leaves
grow continiously
