Structure and Function – How are organisms structured to ensure efficiency and survival?
10.1 - Fundamental life processes depend on the physical structure and the chemical activities of the cell.
♦ Most of the chemical activities of the cell are catalyzed by enzymes that function only in a narrow range of temperature and acidity conditions.
♦ The cellular processes of photosynthesis and respiration involve transformation of matter and energy.




Describe significant similarities and differences in the basic structure of plant and animal cells.

Describe the general role of DNA and RNA in protein synthesis.

Describe the general role of enzymes in metabolic cell processes.

Explain the role of the cell membrane in supporting cell functions.

Science and Technology in Society – How do science and technology affect the quality of our lives?
10.2 - Microorganisms have an essential role in life processes and cycles on Earth.
♦ Understanding the growth and spread patterns of viruses and bacteria enables the development of methods to prevent and treat infectious diseases.



Describe the similarities and differences between bacteria and viruses.

Describe how bacterial and viral infectious diseases are transmitted, and explain the roles of sanitation, vaccination, and antibiotic medications in the prevention and treatment of infectious diseases.

Explain how bacteria and yeasts are used to produce foods for human consumption.

Science and Technology in Society – How do science and technology affect the quality of our lives?
10.3 - Similarities in the chemical and structural properties of DNA in all living organisms allow the transfer of genes from one organism to another.
♦ The principles of genetics and cellular chemistry can be used to produce new foods and medicines in biotechnological processes.

Describe, in general terms, how the genetic information of organisms can be altered to make them produce new materials.

Explain the risks and benefits of altering the genetic composition and cell products of existing organisms.
