Vocabulary Review
Plants
Plant cell with thin
walls responsible for
metabolic reactions
including
photosynthesis
Parenchyma
Part of the root that
contains xylem and
phloem
Vascular
Cylinder/Stele
Type of plant
response that orients
a plant to light
Phototropism
Part of the root that
ensures water and
minerals pass through a
cell membrane before they
enter the stele
Endodermis
Area of lateral or
secondary growth in
stems
Vascular Cambium
Type of plant cell
that provides support
during growth
Collenchyma
Part of a leaf
adapted for maximum
absorption of sunlight
Blade
What constitutes
most of the wood in a
tree
Secondary Xylem
Process of water
uptake and loss by
plants
Transpiration
What can be used to
measure how water
flows in a plant
Water Potential
Type of flowering
plant with netlike
veins, a taproot and
vascular bundles in a
ring
Dicot
Areas of active cell
division in plants
Meristems
Sugar loading in
phloem cells involves
this
Cotransport
Waxy layer in
endodermis that
keeps water in
Casparian Strip
Hormone responsible
for phototropism
Auxin
Hormone responsible
for fruit ripening
Ethylene (only
hormone that is
a gas)
Tissue in plants that
moves substances like
water and sugar
Vascular
Tissue in plants that
primarily stores
things and supports
the plant
Ground tissue
Part of angiosperms
responsible for
reproduction and not
found in any other
major plant group
Flower
Group ancestral to
modern plants or
group that modern
plants evolved from
Charophycean
green algae
Group of plants in
which the
gametophyte
generation is
dominant
Bryophytes
(mosses)
Group of seedless
vascular plants
Pteridophytes
(ferns )
The power source for
transpiration in plants
The Sun
Water properties
that aid transpiration
in plants
Adhesion,
cohesion
These control how much
water is lost due to
transpiration as well as
rate of photosynthesis
Stomates or
Guard cells
Three parts of cell
signaling
Reception,
transduction,
response
Group of plants that
bear seeds but have
no flowers
Gymnosperms
Connections between
plant cells
plasmodesmata
Male gametophyte in
a flowering plant
Pollen grain
The two major groups
of plants that use
pollination
Gymnosperms &
Angiosperms
Process in
angiosperms that
results in a plant
embryo + endosperm
Double
fertilization
Male part of the
flower
stamen
Female part of the
flower
Carpel
The ovule in a flower
becomes a
seed
Triploid tissue in a
seed
endosperm
Male and female
flower parts maturing
at different times
prevent this
Self-pollination
How the sperm
reaches the egg in
flowering plants
Pollen tube
Loss of micronutrients
like magnesium can
result in this, when
not enough chlorophll
is made
chlorosis
Plants get nitrogen
they need primarily
through this process
Nitrogen fixation
by bacteria
Three macronutrients
in plants
Nitrogen,
phosphorus,
potassium
Growth in apical
meristems is typically
referred to
as______growth
Primary
Two major plant
groups whose sperm
are flagellated and
require water for
fertilization
Bryophytes &
Pteridophytes
Type of plant cell
that is typically dead
at maturity and very
thick-walled
sclerenchyma
Sporophyte
generation is
dominant in these
three plant groups
Pteridophytes,
gymnosperms &
angiosperms
