1. The Diversity of Cellular Life
Objectives:
5.0. Identify cells, tissues, organs, organ systems, organisms, populations, communities, and ecosystems as levels of organization in the biosphere.
5.1 Recognizing that cells differentiate to perform specific functions Examples: ciliated cells to produce movement, nerve cells to conduct electrical charges

2. Unicellular vs. Multicellular Organisms
One cell vs. many cells
NOT the same as prokaryotic vs. eukaryotic
Examples of unicellular organisms:
Yeast and spirogyra algae filaments (eukaryotic), bacilli bacterial cells (prokaryotic)

3. Specialized Cells in Multicellular Organisms
Source:
RBC, skeletal muscle, guard cell pair surrounding stomata, stratified squamous epithelial cells

4. Levels of Organization in Multicellular Organisms
Similar cells join together to form…
tissues. Groups of different tissues work together to form…..
organs. Groups of organs that work together to perform a specialized task are called…..
organ systems. All the organ systems work together to complete an organism.
