What to Expect from Study.com Biology 101 Class 📖
What should you expect in the “study.com Biology 101: Intro to Biology”? Let’s break it down.
First of all, this course is full of interesting topics which will make you aware of the basics of biology. You will begin this section with a basic understanding of the fundamentals such as the cell’s structure and role, the molecules that form the building blocks of life including proteins, carbohydrates as well as DNA, and the concept of cell division or reproduction. These are the most fundamental concepts in every living organism, hence these concepts are going to feature numerous times, especially during tests. I promise you, that once you have past these basics the rest of the course will be a piece of cake.
As you go further, you will know genetics and there you will study how traits are inherited from one generation to another and how mutations cause variations in organisms. You’ll also learn some basic concepts of evolution which is in essence the history of how living things have evolved on earth for millions of years. Also, you will take a glimpse of ecology in the concept where you will learn how these organisms relate with each other and the surroundings. Spoiler alert: this is where things become very fascinating when one is in a position to see how one species relates with another as well as the ecosystem.
Lastly, some of the day versions of the course do not only include the basic notions of finance. You’ll also get to learn about more specific topics such as human body systems, plants, and a little of bacteria. This leaves you with a general view of biology which is rather good for it means you are not simply memorizing facts you are encouraged to think like a biologist. Of all these topics, those dealing with the human body, human genetics, and genetic disorders are usually the most frequently tested and as such, should be taken with extra attention.
In other words, when you finish this course, you must have understood the principles that control life on earth. Furthermore, they do not require much effort and added to suitable studying tips (which we are going to discuss in the next section) can make sure to crack that final examination seamlessly.

Key Topics to Focus On 🔑
The ocean of information in Biology might seem too big to navigate, but it is possible to look at topics of interest and save time. These are four important areas you should focus on, together with comparisons, examples from real-life situations, and easy-to-understand descriptions to help you understand these concepts better.
- Cell Structure vs. Cell Function
|
Aspect
|
Cell Structure
|
Cell Function
|
|---|---|---|
|
Definition
|
The physical components that make up a cell.
|
The processes and activities that cells perform.
|
|
Key Components
|
Nucleus, mitochondria, ribosomes, etc.
|
Protein synthesis, energy production, etc.
|
|
Analogy
|
Think of it like a factory’s layout.
|
Like the factory’s day-to-day operations.
|
|
Real-World Example
|
Mitochondria is the "powerhouse" of the cell.
|
Mitochondria generate ATP through cellular respiration.
|
Key Points to Remember:
- Cell Structure: Contains numerous organelles; all of them have some function (nucleus as the place for DNA, ribosomes as the place for protein synthesis, etc.
- Cell Function: The following is how these structures function to keep the cell and the organism alive (For instance how Mitochondria aid in cellular respiration).
Why it’s important: It is important to note that the correlation between the organization of the cell and the operations it performs are some of the essential concepts in biology. These structures are attached to a central nucleus that regulates their movements and formulates the cell’s metabolic activities. Understanding this relationship makes you realize the overall plan of how life functions on such a small scale.
2. Photosynthesis vs. Cellular Respiration
|
Process
|
Photosynthesis
|
Cellular Respiration
|
|---|---|---|
|
Purpose
|
Converts sunlight into chemical energy (glucose).
|
Converts glucose into usable energy (ATP).
|
|
Where It Happens
|
In the chloroplasts of plant cells.
|
In the mitochondria of both plant and animal cells.
|
|
Equation
|
6CO₂ + 6H₂O + sunlight → C₆H₁₂O₆ + 6O₂
|
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
|
|
Real-World Example
|
Plants grow and produce oxygen.
|
Humans breathe and use energy to move.
|
Key Points to Remember:
- Photosynthesis:
- Takes place in plants and some bacteria.
- Converts solar energy into chemical energy stored in glucose.
- Produces oxygen as a byproduct.
- Cellular Respiration:
- Occurs in both plants and animals.
- Breaks down glucose to release energy stored in ATP.
- Uses oxygen and releases carbon dioxide.
Why it’s important: These two processes look very similar and are at the same time opposing Yang and Yin of biological energy. Photosynthesis is the process of absorbing energy and on the other hand, cellular respiration allows energy to be discharged. The knowledge of these concepts will enable you to learn the pattern of energy through living organisms.
3. Mendelian Genetics vs. Non-Mendelian Genetics
|
Aspect
|
Mendelian Genetics
|
Non-Mendelian Genetics
|
|---|---|---|
|
Definition
|
Inheritance patterns described by Gregor Mendel.
|
Inheritance patterns that don’t follow Mendel’s laws.
|
|
Key Concepts
|
Dominant and recessive alleles, Punnett squares.
|
Incomplete dominance, codominance, polygenic traits.
|
|
Real-World Example
|
Pea plant flower color (purple vs. white).
|
Human blood types (A, B, AB, O).
|
Key Points to Remember:
- Mendelian Genetics:
- Simple inheritance patterns involving dominant and recessive alleles.
- Predictable using tools like Punnett squares.
- Applies to traits like flower color in pea plants.
- Non-Mendelian Genetics:
- More complex patterns, including incomplete dominance (blended traits) and codominance (both traits expressed).
- Involves multiple genes or environmental factors.
- Examples include human blood types and skin color.
Why it’s important: At first glance, genetics can be quite confusing, yet understanding the difference between Mendelian and non-Mendelian inheritance does make the process of inheriting a certain trait a little clearer. It makes it possible to/solve genetic problems with confidence knowing what to do and what not to do.
4. Symbiosis: Mutualism vs. Parasitism
|
Aspect
|
Mutualism
|
Parasitism
|
|---|---|---|
|
Definition
|
A relationship where both species benefit.
|
A relationship where one species benefits at the other’s expense.
|
|
Real-World Example
|
Bees pollinate flowers while collecting nectar.
|
Ticks feed on a host animal’s blood.
|
|
Impact on Ecosystem
|
Helps maintain balance and supports biodiversity.
|
Can cause harm and reduce the health of the host population.
|
Key Points to Remember:
- Mutualism:
- Both species gain benefits (e.g., bees and flowers).
- Enhances biodiversity and ecosystem stability.
- Parasitism:
- One species benefits at the expense of another (e.g., fleas on dogs).
- This can lead to health issues for the host species.
Why it’s important: Out of all the concepts in ecology/ I believe that learning about mutualism is critical in order to understand how different organisms coexist in a given environment. Such interactions may catalyze evolution and are a core part of the science of ecology.
