Commonly found in associate's and bachelor's degree programs, Biology 1's broad curriculum provides students with foundational knowledge, preparing them for further studies in the field or to fulfill general education requirements. In addition to attending lectures on biological topics, students usually participate in laboratory exercises that might involve observing organisms under a microscope, performing dissections, creating drawings and performing research on topics discussed in class.
Subjects like taxonomy, reproduction, genetics and the origin of life are normally explored during this introductory course. Students learn about different types of plants and animals, including how they have evolved, how their cells are structured and how they interact with their environment. The human body is explored as students learn about how the various organ systems interact. They also learn about the concepts of genetics and microbiology as they apply to humans, animals and plants.
Here are some specific topics commonly explored in Biology 1 courses:
- Prokaryotic and eukaryotic cells
- Cellular respiration
- Natural selection
List of Common Topics
During this section, students focus a great deal of attention on solving modern biological problems, mainly with an experimental approach. Cell physiology, molecular genetics, DNA, evolution and biochemistry are among the subjects discussed. Using prokaryotes and eukaryotes as examples, students analyze the relationship between cell structure and function.
The normal functions and processes of all major organ systems at the gross, cellular and molecular level are covered in this section. Topics may include basic information on the nervous system, bones and muscles, as well as the respiratory, lymphatic, digestive, circulatory and neuro-endocrine systems.
Genetics and Biochemistry
Genetic and biochemistry topics introduce foundational concepts related to DNA, chromosomes and human genetics as well as elements of chemistry that pertain to living organisms. Students explore genetic diseases, inheritance patterns and characteristics attributed to different types of chromosomes. Topics may also include how enzymes, proteins, amino acids and other chemical structures function in the body.
Plants and Animals
Students learn about organisms and their relationship with the environment around them, using the basic principles of ecology. They study the anatomy, physiology and morphology in regards to plant and animal structure, function and behavior. Lab and field work that further investigate these topics are commonly introduced.
