Flower
Cut flaps by
cutting the FIRST
layer only.
Stem
Label the
systems and
draw the
arrows.
Roots
Label the
parts on the
front.
Leaf
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
reproductive
organ of a
plant
Structure
Function
Anther
- produces pollen
Pollen
- haploid male gametes (sex
cells)
Stigma
- Sticky top of style where
Style
pollen lands.
- Transports pollen to the
ovary.
Ovary
(Fruit)
- Female organ which
produces female gametes.
A ripened ovary is the fruit, the seed
is the embryo.
Adaptation to
Environment
1. Bright colors and
odorous nectar to
attract pollinators.
2. Development of Fruit
for seed dispersal.
Leavesphotosynthetic
organ of a plant
Structure
Cuticle
Function
- Prevents water loss
Mesophyll - Photosynthesis
Veins
- Xylem & Phloem
Stomata
- Lets CO2 in and O2
and H2O out
Adaptation to Environment
1. Thick cuticle in dry
climates.
2. Few stomata to
prevent water loss.
3. Thick stem to store water
(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.
Phloem - Vascular tissue (tubes)
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.
2.Dead Xylem becomes the
wood on the inside of tree
trunks.
3. Can be modified to store
food. Ex: Tubers (potatoes)
and Bulbs (garlic, onions)
Roots
Structure
Function
Epidermis -protection and
& root cap absorption of water
and minerals.
Root hairs -increase surface
area for absorption
of water & nutrients
Root tips - tip of root that is
growing into the
(apical
soil
(area
of
meristem)
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
