Unit B: Diversity of Living Things
Chapter 3: Multicellular Diversity
-
Considerable diversity exists among multicellular organisms, as well.
Specific Expectations:
In the chapter you will learn how to …
B1.2: analyze the impact that climate change might have on the diversity of living things.
(3.4, 3.5)
B2.1: Use appropriate terminology related to biodiversity. (3.3)
B2.2: classify and draw representative organisms from each of the kingdoms according
to their unifying and distinguishing anatomical and physiological characteristics. (3.2, 3.4,
3.5)
B2.4: create and apply a dichotomous key to identify and classify organisms from each
of the kingdoms. (3.2, 3.5)
B3.3: describe unifying and distinguishing anatomical and physiological characteristics
of representative organisms. (3.1, 3.2, 3.3, 3.4)
B3.4: explain key structural and functional changes in organisms as they have evolved
over time. (3.1, 3.2)
