You can do it!!!!
Without gas exchange, a plant
would be unable to
• make food
• make minerals
• absorb sunlight
• absorb water from the soil.
Xylem and phloem are NOT
•transport subsystems
•present in bryophytes
•vascular tissues
•present in ferns.
Which of the following is NOT a
characteristic of all plants?
•are eukaryotic
•produce seeds
•have cell walls
•are multicellular
Plants use the energy of
sunlight to
• exchange gases with the
atmosphere
• carry out cellular respiration
• take in water from the soil
• carry out photosynthesis.
Which of the following includes
all the others?
•Xylem
•Phloem
•vascular tissue
•tracheids
Which term below is LEAST
closely related to the others?
•Fruit
•Ovary
•seed
•cone
Which of the following includes
a plant embryo, a food supply,
and a protective covering?
• pollen grain
• Seed
• Spore
• gametophyte
Living on land required that
plants
• evolve photosynthetic
pigments
• conserve water
• exchange gases
• have cell walls.
If some of the xylem of a young oak
tree was destroyed, it would most
likely interfere with the tree’s ability
to
• conduct sugars to the roots
• absorb carbon dioxide from
the air
• absorb sunlight
• conduct water to the leaves.
A monocot is an angiosperm
that has
•a taproot
•one seed leaf
•branched veins
•two seed leaves.
Ground tissue is found in plant
• stems only
• roots and stems only
• stems and leaves only
• roots, stems, and leaves.
Angiosperms produce seeds
inside protective structures
called
•pollen grains
•Ovaries
•Cones
•petals.
Root pressure
• causes a plant’s roots to absorb
water.
• forces the water in xylem
downward.
• is produced in the cortex of the
root.
• is produced in the vascular
cylinder by active transport.
Which of the following should a
student examine under a
compound microscope to observe
cell division?
• epidermis of a leaf
• xylem from a tree trunk
• tip of a shoot
• phloem from the leaf of a plant
The vascular cylinder of a root
consists of
• xylem only.
• phloem only.
• xylem and phloem.
• xylem, phloem, and ground
tissue.
Which of the following is the only
tissue that produces new plant
cells?
•meristematic tissue
•ground tissue
•phloemd
•xylem
Most of the photosynthetic activity
in plants takes place in the
•mesophyll.
•guard cells.
•stomata.
•xylem.
Water will move higher in a narrow
glass tube than in a wide glass tube
because of
•adhesion only.
•pressure.
•capillary action.
•cohesion only.
The stomata of leaves are usually
open in
• light if a plant has enough water.
• light if a plant has too little water.
• darkness if a plant has enough
water.
• darkness if a plant has too little
water.
Vascular tissue in plants consists of
• meristem.
• parenchyma and collenchyma
cells.
• xylem and phloem.
• epidermal cells.
A seed plant is anchored in the
ground by its
•stems.
•leaves.
•roots.
•trichomes.
Through which plant cells does
water move by capillary action?
•phloem cells
•mesophyll cells
•guard cells
•xylem cells
A carrot is a(an)
•taproot.
•monocot.
•fibrous root.
•extensive root system.
Minerals from the soil move into
roots by
•diffusion.
•active transport.
•transpiration.
•root pressure.
One of the main functions of stems
is to
• carry out photosynthesis.
• transport substances
between roots and leaves.
• store carbohydrates.
• store water.
The attraction of water molecules
to other molecules is called
•adhesion.
•capillary action.
•cohesion.
•transpiration pull.
The sterile leaves of a flower are
the
•carpel and stamens.
•stigma and style.
•filaments and anthers.
•sepals and petals.
A seed that is dispersed to an area
far away from the parent plant
might face less
•Alternation
•germination.
•pollination.
•competition.
Seeds dispersed by animals
typically are contained in
•fleshy, nutritious fruits.
•buoyant structures.
•cones.
•lightweight structures.
Corn, sugar beets, cauliflower, and
cabbage were all developed by
•plant propagation.
•pollination.
•germination.
•selective breeding.
Pollen grains are produced by
• male reproductive structures.
• ovules.
• female reproductive structures.
• flowers.
Most people in the world depend
on food crops such as
• sugar beets, cabbage, and
broccoli.
• strawberries, chilies, and
avocadoes.
• wheat, rice, and corn.
• apples, grapes, and strawberries.
A ripened ovary that contains
seeds is called a(an)
•embryo.
•fruit.
•ovule.
•vegetable.
The seed type shown in Figure 245 that is generally dispersed by
animals is(are)
The early growth stage of a plant
embryo is called
•fertilization.
•germination.
•dormancy.
•pollination.
Seeds that are dispersed by wind
and water typically are
•lightweight.
•nutritious.
•large.
•sweet and fleshy.
