Plants come in different shapes, sizes. Some are short-lived, others live for hundreds of years. Plants have adapted to a wide variety of habitats, and methods of reproducing and dispersing themselves.

According to E. Wilson in his book, "The Diversity of Life" there are aboutspecies of higher plants i. There are about 26, species of algae. Sedentary Plants don't move about. Modular construction - repeating units due to localized areas of growth meristems ; plants grow at their tips and outward in girth. Different modules perform specific functions Roots - anchorage and absorption of water and dissolved nutrients.

Leaves - absorption of light energy and atmospheric gases carbon dioxide.

The study of botany is relevant not just to botanists but also to horticulturists and anyone working with plants from breeding through to nursery growers or agriculturists.

If you understand how plants grow and flower, you can better maintain grow and maintain them. This course contains the basis of plant science, and is an introduction to plant physiology and taxonomy, covering general botany including morphology and anatomy. I am now living in a different world, my whole perspective to life and nature has changed and now I cherish it more. It has broadened my mind and advanced my level of looking at things in my every day work as well.

She would give more positive constructive correction where necessary as if it was not that bad at all. Each lesson culminates in an assignment which is submitted to the school, marked by the school's tutors and returned to you with any relevant suggestions, comments, and if necessary, extra reading.

Living matter is made up of cells. They are the basic structural and physiological units of life. In this lesson you will learn about the structure of various types of plant cells and tissues, and how this relates to the functions they perform. Large tracts of cells with a similar structure that form a collective function are referred to as tissues. Complex organs such as flowers, leaves, stems, roots and fruits are all made up of various types of tissues.

In this course you will learn about the role, structure and development of cells and the roots, stems and leaves that are created from cells. You will also look at the modifications of vegetative parts of plants. When you develop an understanding the fundamentals of botanical science, you then have insights to understand things every time you look at a plant. Everyone encounters plants every day of their life, in their own gardens, when they drive down a road or walk through a park, in both the country and the city.

People who have studied botany will notice the characteristics that differentiate one plant species from another, and how the plant is developing new leaves, flowers and fruits, and the different factors that impact upon its health and growth cycles. Anyone can benefit from studying botany. Horticulturists, farmers, environmentalists and others will improve their employment prospects and skills at work.

When the taxonomy is concerned with plants, it is referred to as systematic botany. Both the terms are often used variously, like chemotaxonomy based on chemical contentcytotaxonomy based on chromosome structure and numbersbiosystematics systematics of living organismsetc. Initially, the taxonomy was based on a few macro morphological informations like habit, sex organ, etc. Later on, the classification was developed after considering many morphological characteristics, the natural systems.

However, modern taxonomy is not restricted on morphology only. It depends on other branches of botany for good information like anatomy, cytology, physiology, phytochemistry, genetics, embryology, ecology etc. Later, init was Herman J. Lam who proposed the term in plant science and it was accepted in the Seventh International Congress Essay 2. Mason considered taxonomy as a vast field in biological science including four main streams.

These are systematics i. On the other hand, authors like SimpsonHeywoodRoss and many others have treated systematics as a field which covers the study of diversity, differentiation and the relationship that exists among the organisms.

According to Solsbrigtaxonomy includes nomenclature and classification but tilt massively on systematics for its concept. The literal meaning of Taxonomy in Greek is putting in order or lawful arrangement and Systematics means putting together. Lam and Turrill boldly expressed their opinion to treat these terms synonymously and later it was followed by many others.

Essay 3. Aims of Taxonomy: The aim of taxonomy includes three aspects I.

Identification, II. Nomenclature, and III. Due to thorough observation of many characteristics of the specimens and development of a classification, this type becomes popularly acceptable.

This type of approach was developed during pre- Darwinian period. This type of approach of classification is based on the interpretation of evolution of a taxon.

This is called phylogenetic classification, which developed during post-Darwinian period i. This type of classification needs the data from the past history of a taxon.

Essay 4. Principles of Taxonomy : Taxonomy is the oldest branch of Botany and was practiced in many countries like India, Greece, Rome, China, England from long back.The identification of plants. Establishing genetic relationships.

Classification 4. The first object of plant taxonomy is to identify all the kinds of plants on earth with their names, distinctions, distribution, habit, characteristics and affinities.

It also tries to correlate the studies with scientific data contributed by various researches in the field of botanical science. The second objective is to arrange the kinds of plants into a scheme of classification or an orderly arrangement. There are some species that are closely related to each other than others. Such species are placed in a higher group; similarly the closely related higher groups to still higher groups and so on. The third objective is to study the factors of evolution to find out the origin of species and their interrelationships.

Hence a taxonomist not only studies the species existing today but also reveals the changes that they have undergone through the past.

The fourth objective of plant taxonomy is the correct naming of plants according to the international code of nomenclature. The naming of the plant is guided and regulated by international rules of botanical nomenclature. In this system, to every plant a binomial name is given e.

The fifth is the documentation which includes the preservation of living or fossil flora in a herbarium. Manson H. It is the fact finding field of taxonomy which includes genetically and cytological studies as well as other techniques applicable to the problem.

It is a method of naming plants based on international rules which permit only a single valid name for each kind of plant. It includes the preservation of living or fossil type specimens and illustrations in a museum or herbarium. By all these fields of plant taxonomy light has already been thrown on plant or plant population, their units, interrelationship, distribution and evolutionary tendencies. Taxonomy is a functional science. The direction and character of its functions are governed by principles.

The principles developed with the increase in knowledge of plants themselves. It developed in the nineteenth century.
