Co-Requisite – Content Standard SB3
Students will derive the relationship between single-celled
and multi-celled organisms and the increasing complexity of
systems.
a. Relate the complexity and organization of organisms to their
ability for obtaining, transforming, transporting, releasing, and
eliminating the matter and energy used to sustain the organism.
Comparative Anatomy




What a queer, funny, little bird a frog are.
When he sit, he squat most.
When he jump, he hop most.
And he ain’t got no tail at all, hardly most.

Essential Questions






How does multicellularity
develop in embryos?
Why do some organisms eat
and others don’t?
How does an organism
change stored energy into
usable energy?
How are organisms adapted
to (transport, metabolize,
excrete, etc.) matter and
energy?
Since all organisms perform
similar processes, what
might you expect about the
stuff of which they are
made?
ETC.
Enduring Understandings




The student will understand that some
organisms consume complex organic
compounds, and others have the ability to
organize these compounds from inorganic
materials using solar or chemical energy.
The student will understand that very small
organisms perform some functions seen in
larger, more complex organisms.
The student will understand that all organisms
carry out metabolic activities within their cells
to transform energy into the chemical energy
of ATP.
The student will understand that all organisms
develop through specialization of structures,
with multicellular organisms forming
specialized tissues for specific functions.
Students will know:




The developmental progress of
multicellular organisms due to
specialization of cells.
The relationships and
differences between
autotrophic and heterotrophic.
The Chemical and Mechanical
processes of (digestion,
transport, absorption, storage,
excretion, etc.)
ETC.
Students will be able to:





Design experiments to test problems
derived from careful observations.
Demonstrate appropriate technique
in all laboratory situations.
Collect, organize, and graph data to
show results of their experimental
design.
Write lab reports with an
introduction of important concepts, a
hypothesis, procedure, organized
results, and a conclusion that
evaluates the results in terms of the
important concepts.
Use data as evidence to support
scientific arguments and claims in
written or oral presentations.

Essential Questions - Excretion



Why is diffusion and osmosis the
only processes of excretion
needed by many organisms?
What is the relationship
between metabolism and
excretion?
How is excretion accomplished
in small and large, multicellular
organisms?
Why is an understanding of
simple excretory structures and
functions important to
understanding complex
structures?
Skills -Students will be able to:


Analyze the chemical
makeup of excretory waste
products.
Write a lab report to include
a discussion of concepts, a
hypothesis, a report of
procedures, results that are
organized, and a conclusion
that discusses the results in
terms of the important
concepts.
Knowledge - Students will know:




That the role of excretion in
metabolism is to remove the
wastes given off during
physiological processes.
That diffusion, osmosis, and
active transport are involved in
accomplishing excretion.
That the excretory structures are
similar in all multicellular
organisms.
The sequence of filtration,
reabsorption and concentration
accomplishes excretion of wastes
in complex organisms.
Evidence of Understanding Excretion




Explain the role of excretion in
metabolic processes.
Compare and contrast the
excretory functions of unicellular
and multicellular organisms.
Compare and contrast the
excretory structures of small,
simple organisms and large,
complex organisms
Explain the processes of filtration,
reabsorption, and concentration of
waste products as they occur in
the human kidney.
