Biology Unit: Tissues, Organs, and Systems of Living Things

Overall Expectations:

 Evaluate the importance of medical and other technological developments related to systems biology and analyze their societal and ethical implications.

 Investigate cell division, cell specialization, organs, and systems in animals and plants.

 Demonstration an understanding of the hierarchical organization of cells, from tissues, to organs, to systems in animals and plants.

Specific Expectations:

 Awareness of ethical issues related to technological development (cloning, stem-cell research, organ transplants, transgenic plants)  Medical imaging technologies (x-rays, CAT scan, MRI, endoscopy) used to diagnose and treat abnormalities in cells, tissues and organs.  Describe public health strategies for diseases like AIDS, SARS, influenza etc.  Cell terminology  Mitosis in plant and animal cells, growth and tissue repair  Compare organelles found in plant and animal cells  Different types of cells found in plants and animals  Cell division in cancer cells  Organ systems and interrelationships between organ systems  Stem cells and meristem cells, cell differentiation
