Online Biology with Lab Overview

Introductory Biology is an introductory course in the biological sciences for the nonmajor student. Topics included are cell structure and function, bioenergetics, DNA structure and function, cell reproduction, taxonomy, evolution, ecology, and an overview of the anatomy and physiology of the major organ systems. This course includes an at-home lab component and supplemental assessments and exercises.
Please note that this lab course requires purchase of a lab kit and completion of lab exercises.  Students must purchase the lab kit as it is not included in the course fee or provided by StraighterLine (More information is available under "Course Text").

Do I have to buy the textbook?
As in many college courses, purchasing the book is ultimately up to you. The StraighterLine courses use reading assignments and practice work from the textbook as supplements, but you will not be required to turn in anything from the book. StraighterLine recommends that you purchase the appropriate text so you are equipped with as many resources as possible (please note that e-books are generally less expensive but may have slight differences in page numbers and resources compared to a hard copy text).

Biology with Lab Course Objectives

After completing this course, students will be able to:

  • Classify living organisms and assess their effect of the biosphere. 
  • Describe the chemical composition of cells and analyze the various processes that happen at the cellular level. 
  • State the different types of cells and distinguish between mitosis and cytokinesis. 
  • Compare and contrast the Mendelian and chromosomal patterns of inheritance. 
  • Enumerate the various applications of genomics and biotechnology. 
  • Trace the evolution of plants.
