A clade is defined as a group that includes an ancestral species and all of
its descendants
Phylogenetic trees show...?
Verified Answer -The evolutionary relationships between organisms.

a. branching ... flowers
b. height ... girth
c. branching ... girth
d. height ... branching
,e. girth ... height
Verified Answer -b. height ... girth
Apical meristems elongate shoots and roots through primary growth.
Lateral meristems add girth to woody plants through secondary growth.
Land plants are composed of all of the following tissue types except
a. meristematic
b. ground tissue
c. epidermal
d. vascular
e. mesodermal
Verified Answer -e. mesodermal
Which of the following cells transports sugars over long distances?
a. parenchyma cells
b. tracheids and vessel elements
c. sieve-tube elements
d. collenchyma cells
e. sclerenchyma cells
Verified Answer -c. sieve-tube elements
Pores on the leaf surface that function in a gas exchange are called
a. xylem cells
b. stomata
c. hairs
,d. sclereids
e. phloem cells
Verified Answer -b. stomata
The solute most abundant in phloem sap is ____.
a. hormones
b. minerals
c. amino acids
d. sugar
e. water
Verified Answer -d. sugar
Phloem transports sugar from a sugar source to a sugar sink.
Water flows into the source end of a sieve tube because
a. water pressure outside the sieve tube forces in water
b. sucrose has been actively transported into the sieve tube, making it
hypertonic
c. sucrose has diffused into the sieve tube, making it hypotonic
d. sucrsose has been transported out of the sieve tube by active transport
e. the companion cell of a sieve tube actively pumps in water
Verified Answer -b) sucrose has been actively transported into the sieve
tube, making it hypertonic
If a plant's stomata are closed an no transpiration is occurring, which of
the following predictions is accurate?
a. Without transpiration, less water will be absorbed from the soil
, b. Without transpiration, the plant's cells will become flaccid
c. Without transpiration, the plant will be water deficient
Verified Answer -a. Without transpiration, less water will be absorbed
from the soil
A student is performing a chemical analysis of xylem sap. This student
should not expect to find much ___.
a. phosphorus
b. sugar
c. water
d. potassium
e. nitrogen
Verified Answer -b. sugar
Phloem, not xylem, transports sugar.
Which of the following statements about transport in plants is false?
a. Although some angiosperm plants develop considerable root pressure,
this is not sufficient to raise water to the tops of tall trees.
b. Most plant physiologists now agree that the pull from the top of the
plant resulting from transpiration is sufficient, when combined with the
cohesion of water, to explain the rise of water in the xylem in even the
tallest trees.
c. Hydrogen bonding between water molecules, which results in the high
cohesion of the water, is essential for the rise of water in tall trees.
d. Weak bonding between water molecules and the walls of xylem vessels
or tracheids helps support the columns of water in the xylem.
e. Gymnosperms can sometimes develop especially high root pressure,
which may account for the rise of water in tall pine trees without
