10 Best Free Online Botany Courses

These free online botany Courses are provided to you when you are not available to go to school and prefer to study at your convenience. You can opt to enroll in any of these courses.

Botany is the in-depth study and understanding of plants. It is essential for comprehending and improving life. It is one of the oldest branches of science that you can pursue. It is also an extensive discipline.

The scope of botany also extends into interesting fields like space travel, agriculture, artificial environments, and hydroponics, with plenty of scope for research.  

The course provides an opportunity for anyone who wants to study the scientific interactions between plants. These interactions include those between the plants and then with the natural environment.

For anyone who loves plants and flowers, this is the subject that will allow you to spend some productive hours with them. The most basic concepts in botany include plant anatomy, cytology, genetics, morphology, physiology, and ecology.

Plants play an essential role in environmental habitation because of the oxygen they release and carbon dioxide they inhale. Many people don’t like plants, and it’s always because they don’t understand how to care for them.

Hopefully, they might change their mind if they take any free botany classes online. This article will give you a better idea of where to start your journey as a botanist.

The learning method has been improved as botany courses are readily available on various learning platforms such as Udemy, Coursera, edX, Alison, and Skillshare.

Listed below are the best free botany classes online for beginners and advanced learners which were carefully selected, so do well to read through and select the ones to enroll in.

  • Herbology
  • Angiosperm: Flowering Plant
  • Master Gardener Series: Basic Botany
  • Plant Bioinformatics Capstone
  • Introduction to Genetic Transformation in Plant Cells
  • Botany I – Plant Physiology And Taxonomy
  • Understanding Plant Metabolism
  • Introduction to Plant Cells and Tissue Culture
  • Diploma in Plant Cell Bioprocessing

1. Herbology

Botany is an important discipline for pharmacology. Such a relationship is much reflected in this course as you get basic concepts in both fields. The beginner herbology class is delivered in Udemy. The class covers vital botany topics like morphology and anatomy, which are fundamental to the field.

However, the majority of it is also related to pharmacy. Not to mention, the instructor is also a pharmacy student.

This course covers three topics which are:

  • Introduction and Classification of Drugs: The first part orients the student on what to expect from the course. It also provides insight into how drugs are classified based on origin, which will be helpful in the final assessment of this course.
  • Plant Biology and Morphology: The second part covers essential botanical concepts like plant tissues, systems, cell contents, cell division, and morphology. It also includes a microscopic examination of plants.
  • Natural Therapies: The last part features six medicinal plants. Some of them are well-known like Ginkgo leaves.

Thus, this course is best only for students who want an introduction to the field of pharmacy and the role that botany plays in it.

2. Angiosperm: Flowering Plant

This is an Udemy course that is more specialized than introductory. This course is all about navigating angiosperms that dominate the earth’s surface and vegetation in more environments, particularly terrestrial habitats.

Since they inhabit the earth more than any other group of plants, angiosperms are the most important ultimate source of food for birds and mammals, including humans.

In addition, this course is highly important to understand the most economically important group of green plants, serving as a source of pharmaceuticals, fiber products, timber, ornamentals, and other commercial products.

An understanding of angiosperms or flowering parts is essential in botany.

Through this course, you’ll learn about the following:

  • Introduction to angiosperms
  • Parts of an angiosperm
  • Fertilization, reproduction, and the life cycle
  • Economic importance of angiosperms

However, because the course is quite specialized, you’ll need at least, the basic biology knowledge, like the life cycle of flowering plants. If you take the course with no prior plant biology knowledge, you may find it more challenging.

Thus, this course is best for students who already have some basic biology knowledge but want a clearer understanding of angiosperms.

Through this course, you can become a professional in biology. Attain high grades and develop your interest in the field of science.

3. Master Gardener Series: Basic Botany

This is a 4-6 hours free online course offered by Oregon State University. It is one of the most comprehensive introductory courses for botany because it covers critical topics that will provide a solid foundation for the field.

You don’t need much experience in botany or science to understand the class. The Course has been designed to help learners identify plants and their non-plant relatives. This includes fungus, algae, lichen, moss, fern, conifer, and seed plants.

This short course aims to help learners recognize the different roles that plants play in a healthy ecosystem

After completing the course, participants will be able to identify all types of plants. In this course, you will also understand the growth and development processes of a healthy plant. As a result of the instructor’s exposition on the basic parts of a plant and all their functions.

As such, this course is best for students who wish for an introduction to the field but have little background knowledge of botany.

This botany course focuses on the following:

  • Parts of a plant: You’ll learn about basic anatomy, leaf types, and root systems. You will also distinguish monocots from dicots.
  • Plant and plant-like classifications: You’ll learn about different plant classes. You’ll also learn the differences between plants and similar-looking organisms, like fungi.
  • Plant processes: Fundamental processes like photosynthesis and respiration will be discussed in detail. 
  • Importance of plants: You’ll appreciate the roles plants play in maintaining our ecosystem.

Furthermore, you will also be given detailed information about the importance of photosynthesis, respiration, and transpiration to plant growth and vigor.

4. Plant Bioinformatics Capstone

This is a Coursera free online botany course. Bioinformatics is one of the most exciting technologies for this generation. This field allows us to unravel information held by plant genes or genomes.

Thus, this course focuses on topics like genes and their functions. You’ll get to learn about gene databases and how to analyze genes properly. In the end, you’ll also make a report from your analysis findings.

Because this course covers quite technical topics like gene analysis, it will not serve as a beginner course in botany.

This course is best for students with intermediate knowledge and experience who want to enhance their bioinformatics skills and understanding of the plant world.
