7.II.Life Science
A. Structure and Function in Living Systems
3. Living systems at all levels of organization demonstrate the complementary nature of structure and
function include cells, organs,tissues, organ systems, whole organisms, and ecosystems. Specialized
cells perform specialized functions in multicellular organisms. Groups of specialized cells cooperate
to form a tissue, such as a muscle. Different tissues are in turn grouped together to form larger
functional units, called organs. Each type of cell, tissue, and organ has a distinct structure and set of
functions that serve the organism as a whole.
e. Classify living organisms according to similarities in structure using a dichotomous key
(kingdom, phylum, class, order, family, genus, species).
