The Biology Corner

Frog by Rick Takmajian

Biology is the study of life and living organisms, from the smallest bacteria to giant sequoias.    Biologists use observation and experimentation to gain an understanding about the natural world.  Branches of biology include anatomy, biotechnology, botany, cell biology, ecology, genetics, medicine, microbiology, molecular biology, and zoology.   Many people entering the field of biology become specialized in a particular area.

As a course, biology encompasses four main themes:

1.  The process of evolution drives the diversity and unity of life
2.  Biological systems utilize free energy to grow, reproduce, and  maintain life functions
3.  Living systems store and transmit information essential to life processes
4.  Biological systems interact with each other, and those interactions possess complex properties.

The Biology Corner is a resource site for biology and science teachers and students.  It contains a variety of lessons, quizzes, labs, web quests, and information on science topics for all levels, including introductory life science and advanced placement biology.    You can find lessons related to biology topics in the links  listed under “topics” on the sidebar as well as specific curriculum for biology classes taught in high school.
