Plants
Let’s begin by reviewing the
characteristics of Kingdom Plantae:
•
•
•
•
•
Eukaryotic
multicellular
Autotrophic
Non-mobile
Reproduce with seeds and pollen
Large Land Plants have vascular tissue, to help them
move water and food materials around within the
plant.
It works very much like our circulatory system, with
arteries and veins.
Phloem takes food (glucose) made in the leaves
during photosynthesis, DOWN to toward the roots,
supplying food for all the plant parts in between.
Write the following
function for phloem on
this side of your foldable:
moves glucose made in
leaves of plants
downward to all plant
parts
Remember!!! Phloem and Food BOTH
make the “F” sound…easy to remember
Xylem is a separate tissue from phloem.
It moves water and nutrients from the
ground Upward.
In your foldable
where the arrow is
pointing, write the
following function of
xylem:
Moves water and
nutrients from the
ground UP
Now go to the next
page in your foldable
and highlight the
definition of vascular
tissue, indicated by
the arrow
Lets continue with
the vocabulary on
this page of the
foldable.
Continue to use
your highlighter to
mark important
terms and
definitions
Geotropism
-Growth movement shown by plants in response
to GRAVITY
More examples of
geotropism
Phototropism is
the growth of a
plant toward the
light source.
Examples of
phototropism
Turn to the
pages with
Plant Parts
Cut the sections
of the plants
apart on the lines
separating them
on both sides.
Turn your foldable sideways and write the term
“MONOCOT” on the left side flap, as shown
Monocot
Turn your foldable to the other side and write the term
“DICOT” on the right side flap, as shown
Dicot
Notice that the functions of each plant part, FLOWERS, LEAF,
STEM, and ROOTS are located under each flap, AND if you will
notice, the sides are different, and specific to the monocot and to
the dicot. Let’s look at these differences:
Monocots
Monocot means that the seed has only 1 or “mono”
seed parts, like sunflower seeds or corn.
Corn
Grass seed
Monocots
Flower petals are in multiples of 3’s
Leaves are usually long and slender and
veins all run parallel
Monocots
Roots tend to be fibrous or a bulb shape
Dicots
Dicot means that the seed has 2, or “di” seed
parts, like a peanut or a pinto bean.
Dicots
Flower petals are in clusters of 4 or 5’s or multiples
of 4 or 5.
Leaves are usually long and slender and
veins all run parallel
Dicots
Roots are called tap roots, and have a
main root, with smaller branching off of
it.
Now we will take a look at each part of
the plant and highlight their function.
Lets start with the flower. What is the
purpose of the flower?
Flowers are reproductive
structures that are often times
brightly colored and fragrant to
attract birds/insects to aid in
pollination.
Flowers contain both male and female parts for
reproduction.
Leaves
Leaves are adapted to trap sunlight during
photosynthesis. They also allow for gas exchange
through the stomata.
Look on the BACK of your foldable for a picture
of the stomata and guard cells.
Stomata & Guard cells in leaves
The stoma is the actual
opening for gas exchange in
the leaf. They are very small
and there are many on each
leaf.
The guard cells AROUND the
stoma open or close, to
control:
•amount of gas exchange
•time of gas exchange.
Now flip back to
your vocabulary
terms and highlight
the stomata and
guard cell terms
and definitions.
Leaves
Leaves also have a cuticle.
The cuticle is a waxy layer that covers
the surface of a leaf. Its main
purpose is to protect the plant from
bacteria, fungi and viruses, as well as
to prevent water loss.
Now flip back to
your vocabulary
terms and highlight
the cuticle term
and definitions.
Leaves
Leaves also exhibit phototropism, which is
a plants growth toward sunlight.
Stems
Stems give structural support for the leaves
and flowers and contain the xylem and
phloem to transport materials around within
the plant.
Some plants have woody stems, like trees.
Other plants have soft tissue stems, like
garden plants. Those are called herbaceous
stems
Roots
The function of roots is to anchor the
plant to the ground and to absorb
water and minerals from the ground.
Two important points to remember about
roots:
1.Roots can be fibrous or a taproot
2.Roots exhibit geotropism
photosynthesis
The most important factor that distinguishes
plants from other kingdoms is the fact that
they photosynthesize.
This process happens in the chloroplasts of
each and every leaf cell of the plant.
Fill in the following photosynthesis formula on the
back of your foldable.
