Slowing of stem Ethylene
elongation, thickening and
curvature of the stem to
start growing horizontally
are all part of a growing
shoot's response to
Transcriptional regulation Response
and post-transcriptional
modification are most
closely associated with
which stage of a signal
transduction pathway
In addition to absorbing Taproot
water and minerals from
the soil, this type of root
provides enhanced
anchoring of the plant to
the substrate
These sugar-conducting Sieve-tube elements
cells lack nuclei and
ribosomes and are
intimately associated with

As a youngster, you drive 1.5 meters
a nail in the trunk of a
young tree that is 3 meters
tall. The nail is about 1.5
meters from the ground.
Fifteen years later, you
return and discover the
tree has grown to a height
of 30 meters. How tall is
the nail above the
ground?
Based on the ABC model, Sepal-petal-petal-sepal
what would be the
structure of a flower that
had normal expression of
genes A and B but lacked
expression of gene C?
Suppose George Xylem
Washington completely
removed the bark from
around the base of a
cherry tree but was
stopped by his father
before cutting the tree
down. The leaves retained
their normal appearance
for several weeks, but the
tree eventually died. The
