Focus Question: How do
plants get the resources
they need to survive?

2. Transport Systems Review
nimals are living organisms
•Made of living cells
•Every cell is provided with resources to keep it
alive
What Do We Know About Plants?
re plants living organisms?
re plants made of cells?

3. Water Needs
hink of a plant in your garden
ow does the garden plant get the water it
needs?
ow does water get from the roots to all the
cells in the plant?

4. Celery
his is a garden plant. It has stems and
leaves, but something is missing.
hat is missing from this plant?
ill these plant stems be able to get water for
their cells without roots?

5. Celery Experiment
esign an experiment to get information
that will help you find out how water
gets to all the cells in a celery plant.
otebook sheet has a list of materials
available.
ork in groups to come up with a
question and then design an

6. ook at the differences between these two
examples of celery
s you plan, think about:
•Leaves might affect how celery interacts with
water.
•Mass of the celery might change.
•Volume of water in the vial might change.
ave 15 minutes to come up with a testable

7. Design Discussion
hare question and experimental
designs
uestions or suggestions for changes and
refinements
inal adjustments to plans

8. Experiment Set-up
et the materials you need and record the
measurements for starting conditions.
abel your experiment and set it up in the
window when complete
iew class color demonstration

9. Observe Results
bserve the condition of the stalks and the
amount of water in each vial
hat is the general condition of the celery
stalks?
ow did the water in the vial change?

10. Measurement Data
se measuring tools to get data about
the mass of your celery stalks and
volume of water in vials.
ow much water was in non-celery vial?

11. Organize Data
hat is a useful way to organize our data?
hat headings should go at the top of the columns?

12. Analyze Results
ompare volume of water missing from
non-celery vial to your vials.
here did the missing water go?
ompare starting and ending masses of
celery to see if the ending mass could
account for the missing water.

13. Color Demonstration
tudy celery and cross-section that was in
colored water.
hat did you observe when you first looked at
the celery stalk that had been in the red
water?
hat did you observe when you looked at the
cross-section of the celery stalk?

14. hat is the relationship between the red
dots and water in the celery stalk?
eview the question you wrote at the
beginning of the experiment and the
data you gathered.
rite your conclusions on your notebook
sheet.

15. Vascular Plant Questions
hat specialized structures in vascular plants
transport sugar?
hat specialized structures in vascular plants
transport water and minerals?
n what ways are the transport systems the same for
plants and animals?
n what ways are the transport systems different for
plants and animals?

16. Vocabulary
ross section - Cuts across an object and
exposes its internal structure
ascular Plant - A multicellular plant that
has vessels for transporting water,
minerals, and sugar to all its cells

17. ylem - Tubes to transport water and
minerals to cells
hloem - Tubes to transport sugar to
cells
Sap - Sugar-rich liquid “food” flowing
through the phloem tubes to cells that
cannot make their own food.

18. Concepts
hat structures do vascular plants have for
transporting water?
•Vascular plants have internal tubes called xylem
to carry water and minerals from a plant’s roots
to its leaves.
hat structures do vascular plants have for
transporting sugar?
•Vascular plants have internal tubes call phloem to
carry sugar-rich sap from a plant’s cells that
produce sugar to its cells that do not produce
sugar.
