Fold your

half.

System
Cut flaps
by cutting
the FIRST
layer only.
Fill in your foldable
with the notes
provided. Structure
will go on the left side
and function will go on
the right. Adaptations
to the environment
will go on the back.
Flowers
Structure
Function
Anther
-produces pollen
Pollen
-haploid male gametes
(sex cells)
Stigma
& Style
-Sticky top of style where
Ovary
(Fruit)
- Female organ which
pollen lands. The Style
transports it to the ovary.
produces female
gametes. A ripened ovary is
the fruit, the seed is an embryo.
Adaptation to
Environment
1. Bright colors and
sweet nectar to attract
pollinators.
2. Development of Fruit
for seed dispersal.
Leavesphotosynthetic
organ of a plant
Structure
Function
Upper
Epidermis
-contains cuticle
prevents water loss
Palisade
Mesophyll
-Light reactions of
photosynthesis.
Spongy
Mesophyll
-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 in dry
regions. (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 glucose (food)
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
absorption of water
and root
and
minerals.
cap
-increase surface
Root hairs area for absorption of
water & nutrients
Root tips
(apical
meristem)
- tip of root that is
growing into the soil
(area of mitosis).
Adaptations to the Environment
1. Can be modified to store starch and
sugar. (Carrots, Beets, Turnips)
2. In dry climates taproots form & can be
extremely long to reach & store water.
3. Fibrous roots are good for preventing
erosion and getting surface water due to
being a thin and branching root system.
4. Capillary Action - force that allows the
roots and the stem to absorb the water
up in to themselves, against the force of
gravity
