In addition to a core set of biology courses in these programs, most feature electives such as microbiology, botany, or zoology. Students graduate with a number of valuable skills in communication, research, and analysis. 

Below are some of the most common biology courses in a bachelor's degree program, whether online or in-person:

General Biology

In this introductory course — typically the first in any biology program — students are given a broad overview of life and living organisms. After learning how all organisms are made up of cells, students explore how hereditary information is encoded in genes. Of particular interest is the role of genes in the human body and how they influence our health and lifespan.


This course examines the history and development of plants, animals, and single-celled organisms. Some of the topics covered include patterns of biological diversity, genome sequencing, animal behavior, and natural selection. Students learn how species interact within ecosystems and how environmental factors can affect evolution.

Organic Chemistry

Building upon knowledge obtained in a general biology course, students explore the molecular structure of cells. Additionally, students learn about the properties, reactions, and preparation of the carbon-containing compounds produced by living organisms.

Organic Chemistry or General Biology Lab

Biology programs often include hands-on lab courses in biology, chemistry, or both. They give students the opportunity to observe, experience, and experiment with scientific phenomena. In the online environment, students engage in experiments by conducting them at home using everyday objects or lab kits — typically available from the school for a fee — or by watching simulations or online demonstrations.


This course explores the most basic study of physical science. Coursework covers the structure of matter, how objects interact, and how energy and various types of force influence the way matter moves and behaves. Students learn to consider objects from both a macroscopic and submicroscopic level to try to understand scientific phenomena.

Career Opportunities for Biology Graduates

Although biology is a flexible major that can lead you to pursue a number of different directions, many students opt for careers in the health and medical field or education. After earning bachelor's degrees in biology, graduates can move directly into the workforce or continue working toward advanced degrees, such as a Master of Science in Biology, a Master of Education with a biology focus, or a Master of Environmental Science, to name a few options.

Is an Online Biology Degree Worth It?

Deciding whether to pursue an online bachelor’s degree in biology requires careful consideration. Prospective students may want to examine some of the specific advantages and disadvantages: 

Potential Benefits

This is a versatile degree. Pursuing a bachelor's degree in biology helps students develop valuable skills, such as critical thinking, analysis, and communication, which are useful in many fields beyond health care and science.

Careers in biology-related fields are growing. Holding a bachelor’s degree in biology can lead to a higher-than-average chance of employment. Of the top 10 career fields individuals with a bachelor’s degree enter, seven have a higher than average growth expectation. The median salary for biology-related fields is $65,000 which is also higher than average.

Online biology programs can be convenient. Studying biology online allows students to enroll in the best program that fits their academic interests and financial needs without having to move to a different location.

Potential Drawbacks

A bachelor's degree may have limitations compared to more advanced degrees in this field. A fairly high number of biology professionals — 58%, according to the BLS — have earned advanced degrees so graduates may need to consider earning at least a master's degree to be competitive in this field.

Online programs can be isolating. For some students, online programs can cause them to feel isolated from classmates and instructors. This means they may have to work harder to connect with others through online discussion forums.

It may be harder to work or perform research during the COVID-19 pandemic, which society will be struggling with for decades to come.According to a 2020 research study by Genome Biology, 77% of institutions were shut down during the beginning of the pandemic and 49% of scientists reported their research was slowed down. New and improved online collaborative platforms have made working and researching from home easier, but there are still drawbacks to travel restrictions and the dangers of in-person experiments.

Students also need to factor in their own personal circumstances, such as budget constraints and work and family obligations. Ultimately, individuals must decide for themselves whether the benefits they expect to receive from earning a biology degree are worth the investment of time, money, and energy.


Students pursuing online degrees in biology should ensure the schools they're considering are accredited. For an institution of higher education, accreditation occurs when all of the college's programs, faculty, and student resources are evaluated and approved by an independent agency that has been sanctioned by the Council for Higher Education Accreditation or the U.S. Department of Education. Individual programs within a school can also be accredited by other approved agencies, and some biology programs have earned this additional programmatic accreditation from the American Society for Microchemistry and Molecular Biology.

Choosing an accredited program offers three main benefits:


Perhaps most important, accreditation assures students they're enrolled in a credible online degree program that meets high standards for quality and academic rigor. 


Enrollment in an accredited school is also a requirement to qualify for financial aid and for acceptance into most graduate programs. 


Finally, depending on a student's career path, it may be a requirement for obtaining licensure.
