Plant classification or the science of naming and classifying plants is known as taxonomy. Taxonomy is an important part of botany and because they are used in so many areas it is really necessary to know whenever you plan a career in botany. You don’t have to start plant taxonomy online course right away, but if you do this now, you will have a better understanding of classification of plants.
This plant taxonomy free online course on collegelearners.com takes you through the practical and theoretical aspects of the taxonomy of flowering plants. The plant taxonomy online course examines the nature, need and functions of plant taxonomy with emphasis on identification, classification, principles and practices of naming plants including nomenclature.
Plant Taxonomy is an introductory course to plant taxonomy expanding on plant morphology, phylogeny and naming. Plant taxonomy provides the basis for understanding our life as plants provide essential air, food and materials for our survival. Without a good taxonomic grasp we cannot understand where modern cultivated plants have come from, where their ancestors originated and how they are related to one another. Consequently the course looks at different types of plants in the context of their distribution, morphology and origins. The course uses numerous photos and video clips to illustrate the concepts being discussed allowing you to ‘meet’ many of the plants under discussion.
Plant Taxonomy (i.e. the scientific identification of plants) has been increasingly sidelined and neglected in horticulture, agriculture, botany and science courses. This short course is a great way to become proficient in understanding the essentials in plant taxonomy.
To the ill-informed, it is a low priority for gardeners, environmentalists or farmers to identify obscure parts of a plant; or place plants into a high level scientific classification such as a family or class. For anyone who understands these industries well however, it can be critical to have that knowledge. Taxonomy trains people to observe the finer details that separate one plant cultivar from another. It provides a framework that makes the process of identifying plants systemic.

Learn to Classify Plants & Understand Differences Between Plant Groups
Study this course to learn how to systematically examine a plant’s distinguishing characteristics, then determine its scientific classification based upon those observations.
This course provides a solid footing in plant taxonomy. It begins by introducing the binomial system and ranks of classification and then goers on to explore botany including all the different parts of plants in detail – roots, shoots, leaves, flowers, and fruits.
Students also learn about collecting, pressing, dissecting, drawing and analysing plant material. We then go into detail about the use and design of plant keys for identification purposes before a comprehensive exploration of all the major plant groups.
There are ten lessons in this course, each requiring approximately 10 hours of work including reading, additional research, completing the set tasks and assignments.
The content of each of the 10 lessons is as outlined below:
1. Introduction to Taxonomy
2. Describing Plant Parts
3. Recording & Analysing Plant Descriptions
4. Taxonomic Techniques
5. Primitive Plants
6. Seed Plants
7. Phylogeny of Land Plants
9. Dicotyledons (Part I)
10. Dicotyledons (Part 2)
Scientific Plant Classification
The scientific system uses levels to classify plants by dividing them into groups which have similar physical characteristics. These groups are then divided into smaller groups with more similar characteristics. These are divided again, and so on. Therefore, the division of group to subgroup, and subgroup into further subgroups continues until you finally have only one type of plant in each group.
In the scientific system of plant classification there are over half a million species of plants. The classification of plants, like the classification of anything else, is based on the idea of grouping together things which are similar. Species are groups of individual plants that have a range of similar characteristics and are capable of freely interbreeding with each other. That is, the pollen from the flower of one plant can successfully pollinate the flowers of another and the sperm in that pollen can fertilise the egg cells in the ovules of the second plant. This results in a fertile seed which will germinate and produce a new fertile plant that resembles its parents. It should be noted that just because two plants can be hybridised in our gardens this does not automatically make them members of the same species.
Species are grouped together into collections of species which are fairly similar. These groups are called genera, with the singular being genus. Genera are grouped into collections of genera which have a relatively great similarity to each other. These are called families. Families are the level which most horticulturists start at, and then work down to genus and species. In fact, it could be argued that the only way to gain a reasonable grasp of plant identification and culture is to learn plants by their family as well as their genus and species names. Familiarisation with plant families enables a person with no prior knowledge of a particular plant to be able to place it in a family and make an educated guess as to its growing requirements, susceptibilities to environmental factors, possible form and shape, and a range of other likely characteristics.
Why Plant Taxonomy is Important
Accurate plant identification is more than just a means of avoiding poisonous plants. It is a skill which should be an essential requirement for anyone working with plants and especially in horticulture. Taxonomy is the term used to describe the practice and science of naming and classifying any organisms, and in our case plants. It relies on accurate descriptions and rules of nomenclature to facilitate identification. To attempt to select, grow, and use plants in any context without taxonomic skill is at best foolhardy, and at worst it can be outright dangerous.
There are also economic reasons for being able to identify plants. The development of new plant cultivars can be time-consuming and costly, but it is very important to commercial horticulture to continually improve the cultivars available in terms of productivity and quality. Anyone who devotes significant resources to developing a new cultivar needs to be able to establish and prove their commercial rights to that plant to obtain fair and profitable gain from their investment. Systems for establishing such rights exist in most developed countries.
Who Will Benefit from Studying this Course?
This course is essential studying for anyone who works in the horticulture industry. Whether you have previously studied some taxonomy previously, or whether you are new to this subject, you will find this course fulfilling.
The course is aimed primarily at those working in the fields of – botany, plant taxonomy, horticulture research, botanical gardens, general horticulture, cut flower industry, gardening, garden design, landscaping, and garden tourism. It is also suitable for anyone who wishes to brush up on their taxonomy skills or with a general interest in being able to name plants and understand plant morphology.
