Study Set Content:
seed that have one or two seed leaves
Cotyledons
tubular with pith in the center are common in ferns
Siphonosteles
the cork cambium may also produce parenchyma-like
phelloderm cells
although (blank) may develop secondary tissues
cambia
makes up the outer bark of woody plants
cork tissue
plants that die after going from seed to maturity within one growing season, have the green herbaceous stem. Most monocots are annual
Annuals
the cork cambium produces box-like
cork cells
herbaceous dicot stems have what kind of bundles
discrete vascular bundles composed of patches of xylem and phloem
cork cells are impregnated with what
suberin
central cylinder that is composed of primary xylem, primary phloem and pith in most younger and few older stems and roots
Steles
cork tissue function
reducing water -loss and protecting the stem against mechanical injury
vascular bundles separate
the cortex and the pith
vascular bundles are arranged in cylinder
in cylinder
waxy substance impervious to moisture
suberin
develop from seeds with a single cotyledon
Monocotyledon
when are suberin produced
annually
the annuals of dicots are largely
primary
xylem that is produced after the spring wood, and which has smaller or fewer vessel elements and large number of tracheids
summer wood
relatively large vessel elements of secondary xylem that is produced when the vascular cambium of a typical broadleaf tree first becomes active in spring
spring wood
what kind of trees where the vascular cambium and the cork cambium is active all-year
tropical trees
