Down on the wet ground.
24. How do Non vascular
plants receive water and
other nutrients?
Absorb it from the
ground by osmosis and
diffusion
25. Why do the non
vascular plants have to
remain small?
They do not have tubelike
cells to transport their
water and nutrients.
26. Describe moss:
Tiny fuzzy plants, look
like little trees that grow
on the soil, or on tree
bark.
27. Describe Liverworts:
Flat, large leave plants that
grown close to the ground.
28. What are Rhizoids:

and leaves.
c) Have tube like cells to
move water and other
nutrients through the plant.
33. What are Ferns?
A fern is a Primitive
Vascular plant that still
reproduces by spores.
34.Why are ferns often
used in decorating homes
and offices?
Primitive! Ferns do not
require as much light to
survive.
35. Where would we find
ferns?
Moisture content must be
high:
WETLANDS
FIELDS
FOREST
36. Ferns reproduce by
spores. Where are the
spores located?
In spore cases on the
back of the fern leaves.
37.Name the fern leaf:
frond
38. What are leaflets?
Tiny divisions of the fern
frond.
39. Describe the fern
stem:
The fern stem grows
UNDERGROUND for
protection! Then the
fronds shoot up all along
the sides of the stem.
.40. Describe the steps of
the fern life cycle:
a)Spore case opens
b)Wind carries the spores
to some wet area
c) Spores grow into a heart
shaped plant.
d) Heart shaped plant
produces sperm and egg.
e) Fertilization
f) Develops into a new fern.
41. What is the most
common land plant?
SEED PLANTS!
42. What is a
seed?
Seed = Part
of the plant
that contains
a young
plants.
.
43. Draw a picture of a
cross section of a seed:
44.What is a conifer?
A plant that produces a
NAKED seed inside of a
woody cone. Called a
GYMNOSPERM.
.45. List three examples
of conifers:
Pine
Cedar
Spruce
46. Describe the conifer
leaves:
Needle shaped.
47.Why are conifers
called EVERGREENS?
Whenever a conifer drops
a needle shaped leaf, it
grown another one. Keeps
a full load of fresh
leaves all year long.
48. Differentiate the two
kinds of conifer cones:
Long, tender pollen cone
that produce pollen.
Female cone: Big rough
woody cone that houses the
naked seed.
49. Explain how
fertilization occurs in
pine trees.
a)Pollen cones
release their
yellow pollen
(sperm)
b)Wind blows
the pollen
into the
woody cone.
a)Woody cone
gets pregnant
and forms seed
b)Seed blown by
the wind onto
fertile ground
where it
grows.
50. Describe
the roots and
stems of the
conifer:
Hard, thick,
and woody
51. Where would you
expect to find conifers?
Conifers can be found in all
climates.

53.What is an
Angiosperm? (flowering
plant)
Any plant that produces a
flower during its
lifecycle.
54.What is a
flower?
The SEX
ORGANS
of the
plant.
55. Describe the life cycle
of the flowering plants:
a)Occurs in the flower
b)Male part makes pollen
c)Female part makes the
egg.
d) Flower gives off a
sweet odor to attract
insects.
e) While insects are
feeding on the nectar,
pollen sticks to their
hairy legs.
f) Then the insect flies off
hopefully into a female
flower, pollen falls off,
flower gets pregnant and
produces a seed.
55.There are 9 times more
flowering plants than any
other kind of plant.
.56. How could you tell
that a certain plant was a
flowering plant if there
was no flowers on it?
Look on the
back of the
leaves.
All flowering
plants have a
network of
veins on the
back of the
leaves.
57. Important uses for
flowering plants:
a)Decoration
b)Food!
c)Production of oxygen
during photosynthesis
1. WHY IS THE LEAF
CONSIDERED THE PLANT
FACTORY?
This is where the sugar
molecules are put together.
2.Why are leaves useful
for identifying plants?
All leaves have unique
features that are
specific for that specie
of plant.
3. Label the following
parts of the leaf:
Blade
Stem
Stalk
Midrib
Small Vein
4. Identify the following
terms:
Stalk: Connects the
stem to the leaf.
Midrib: Large vein in
the center of the leaf
Blade: Green portion of
the leaf
Small veins: Transports
nutrients from midrib to
the interior of the leaf.
5. Explain how leaves
vary in size:
Leaves vary in size from
the tiny leaf of the
duckweed to the large 3story leaves of some
tropical plants.
6. Draw and label the
different types of edges
that we find on leaves:
Smooth
Toothed
7. Discuss the vein patterns
that are found on the back
of the leaves:
The vein patterns are
formed by the midrib and
the attached smaller veins.
8. Draw and label the
three ways that leaves are
arranged on the stem:
Opposite
pattern
Alternate
Pattern
Whorled
Pattern
9. What is one thing that
all three leaf groupings
have in common?
The leaves do not overlap.
The leaves are arranged
so that each leaf receives
the maximum amount of
sunlight.
10.Identify the following
cell layers of the leaf:
Wax layer: Layer of wax
found on the top and
bottom of the leaf. Its job
is to keep insects out and
water in.
Upper Epidermis: A layer of
single cells located under
the wax layer. It also
protects the leaf from
insects and water loss.
Palisade layer:
Found under the Upper
epidermis, it is made up of
long thin, tightly packed
photosynthetic cells
Spongy layer:
Located under the Palisade,
it is made up of loosely
packed photosynthetic
cells. Lots of air spaces for
incoming air and water.
Leaf vein:
Small vein coming in
between the palisade and
spongy layer.
Made up of xylem and
phloem cells.
List and describe the two
types of tube like cells
found in the vein:
Leaf vein:
Xylem cells: Transport
Water into the leaf.
Phloem cells: move Sugar
Out of the leaf.
Lower Epidermis:
Found under the spongy
layer next to the bottom
waxy layer.
Stoma: A small pore in
the lower epidermis.
Plural = stomata
What does the stoma do:
Allows air with Carbon
dioxide to enter the leaf.
What are guard cells and
what do they do?
Guard cells are two bean
shaped cells found on each
side of a stoma. They
control the size of the
stoma.
11. How does water leave
the plant?
Water drips out of the
stoma onto the surface of
the leaf.
12. What is transpiration?
Transpiration describes
the overall process of the
plant losing water.
Considering all the water
that is taken in by the
roots, how much of this
water is lost due to
transpiration?
14.What is Turger?
Strength due to a constant
water pressure within the
xylem cells of the plant.
15.What is wilting?
A loss of strength due to a
drop in water pressure
within the xylem cell of
the plant.
16. Explain how the stoma
and guard cells try to keep
the plant from wilting.
The guard cells are on
each side of the stoma.
One dry days, the guard
cells swell up and close off
the stoma to prevent
water from coming out.
17.Why would you consider
a greenhouse an ideal
environment for plants to
grow?
The climate is warm and
wet.
18.How did people once
believe that plants got
their food?
They believed that plants
ate the soil.
19. How do plants really get
their food?
They use a metabolic
process called
photosynthesis.
20.What is the food
product produced by the
plant?
Sugar
21.Why does the plant
produce sugar?
To have a place to store
the energy that it
absorbed from the sun.
22. Why can plants absorb
energy from the sun while
animals can’t?
Plants have chloroplast,
animals do not have this
organelle.
Fill in the blanks!!!
There is energy in the
Sun
The plant Needs This
Energy! So, the plant
uses its Chloroplast
Which is full of
Chlorophyll To get this
Energy.
The plant needs a place to
Store This energy, so it
builds
sugar
It needs some raw
materials to build with, so
it takes in CO2 from the air
and Water from the soil
through the roots.
It combines the CO2 from
the Air with the Water to
make the sugar. The
unused Oxygen is released
into the atmosphere.
24.What two things does
the plant use the sugar
for?
a)Energy for metabolic
process.
b) building materials
25. Why do animals, even
humans, have to eat plants?
To get energy!
26. How long does a plant’s
leaves stay green?
As long as there is plenty
of sunlight!
27.What causes leaves to
stay green during the
spring and summer?
High levels of sunlight
28.What other colors are
found in leaves?
Yellow, reds, and Browns
29.Why do we see the
other colors in the fall?
Low levels of sunlight, the
plant stops making
chlorophyll.
30.Why do all living things
depend on
photosynthesis?
a)Food for energy
b) maintain oxygen in the
atmosphere
31. Practical uses for
leaves:
a)Produce oxygen
b)Food
c)Flavorings or spices
d)Drugs
e)Identifying plants
f)decorations
