Biological Processes and Systems
Interactions Among Plant Systems
Purpose
The purpose of this station is to reinforce your understanding of how plant systems interact to
perform the functions of transport, reproduction, and response.
Before You Begin…
Check to see that all the items are present and organized according to the station information
sheet. If you notice a problem, notify your teacher immediately.
Materials
Tropisms and Function cards
(1 set in envelope) EX:
System Parts Interaction cards
(3 cards in envelope) EX:
Plant Systems Interaction Flowchart
Essential Question
In order for a plant to survive, why must its different systems interact?
Activities and Questions
1. Locate the Tropism and Plant Events cards. Use the tropism cards to review the concepts of
phototropism, geotropism, and thigmotropism. Then take a look at the Plant Events cards, which
show pictures of different plants responding to stimuli.
How is it beneficial for a plant to respond to different stimuli in its environment?
Find the Plant Systems Interactions Flowchart. Remove the cards from the envelope and place
each System Parts Interactions card on the flowchart as shown below.

Interactions
The System Parts Interaction cards list parts or processes that are part of the systems found in
plants. For example, in the transportation system, the xylem and phloem are cell types that
perform some of the functions in the system.
2. How do the system parts identified in the system parts interaction card for the transport
system interact in the leaves, stems, and roots of a plant so that the plant benefits from the
system?
3. Explain the effects of
 Thigmotropism on a plant’s tendrils:

Phototropism on the stems and leaves of a plant:

Geotropism on the roots and leaves of a plant:
4. Remove the System Parts Interactions cards from the Plant System Interaction Flowchart. Read
the definition for each of the three systems.
Explain the interactions that occur among the reproductive, transport, and response systems that
enable a plant to grow, thrive, and reproduce.
5. Now that you have completed these questions, return to the Essential Question.
