monocotelydon
1 seed leaf
example of a monocotyledon plant
tulip
dicotyledon
2 seed leaves
example of a dicotyledon plant
rose
how are veins arranged in a monocot
parallel
what type of veination do dicots have
netted
give 3 differenced between a monocot and dicot
monocot
-have parallel veination
-have scattered vascular bundles
-have 1 seed leaf
dicot
-have netted veination
-have rings
-have 2 seed leaves
name the hard material that reinforces xylem
lignin
where is the xylem located in the stem of a young dicot plant
in the centre beside the phloem
name a structure in stems that allows for gaseous exchange
lenticles
what is the function of meristematic tissue
areas of growth
name a vascular tissue composed if living cells
phloem
identify 2 structural features in phloem
sieve tubes
companion cells
2 ways xylem is adapted to transport water
narrow
has piths
lignin
name a plant tissue that is considered non living
xylem
why are xylem considered non living
they are dead at maturity
give the precise location of xylem in the stem
beside the phloem in vascular bundles
give 2 functions of xylem
transport water
transport minerals
xylem have a different location in a young root vs a stem. describe this difference
a root only has 1 vascular bundle in the centre while a stem has many
