Transcript Overview of Plant Systems

Structure and
Function of
Plants Review
and Foldable
Fold your
sheet in
half
along the
crease
line.
Structures
Functions
Open
your
foldable
and
label it
like this.
Cut flaps
on folds
by cutting
the first
layer only.
Fill in your foldable
with the notes
provided. Structure
will go on one side and
function will go on the
other. Adaptations to
the environment will
go on the back.
Flowers
Structure
Function
Anther
-produces pollen
Pollen
-haploid male gametes
(sex cells)
-Sticky top of style
Stigma &
where pollen lands.
Style
The Style transports it
to the ovary.
---------Female organ which
Ovary
produces female
gametes
Adaptation to
Environment
1. Bright colors and
sweet nectar to
attract pollinators.
2. Development of
Fruit for seed
dispersal.
Leaves
Structure
Function
Upper
Epidermis
-contains cuticle
prevents water loss
Palisade
Layer
-Light reactions of
photosynthesis.
Spongy
Layer
-Calvin cycle (stores
CO2)
Lower
Epidermis
-Lets CO2 in and O2
and water out
(stomata)
Adaptation to
Environment
1.Thick cuticle in dry
climates.
2.Few stomata to prevent
water loss.
3.Reduced surface area to
prevent water loss.
(Cactus)
Stems
Structure
Xylem
Function
-vascular tissue (tubes)
that carry water from
the roots to the leaves
for photosynthesis and
to other parts of the
plant.
-Vascular tissue (tubes)
Phloem that carry sugar from
the leaves to other parts
of the plant.
Adaptation to the
Environment
1.Stiff cell walls for trunks
and branches. Dead
Xylem becomes the wood
on the inside of tree
trunks.
2. Can be modified to store
food. Ex. Tubers
(potatoes) and Bulbs
Roots
Structure
Function
Epidermis -protection and
and root
absorption of
cap
water and
minerals.
-increase surface
Root hairs
area for absorption
Root tips
- tip of root that is
(apical
growing into the
meristem)
soil (area of
mitosis).
Adaptation to the
Environment
1.Can be modified to store
starch and sugar.
(Carrots, Beets, Turnips)
2. In dry climates root
systems can be
extremely long to reach
water.
