Plant Taxonomy
Kingdom Plantae is divided into the following four phylum. The important characteristic features of the different phyla of Kingdom Plantae.

Features |
Examples |
|---|---|---|
|
Nonvascular plants |
They are small; lack roots, stems, and leaves. They lack a vascular system for transporting water and nutrients.; and produce spores rather than seeds. |
Mosses and Hornworts |
|
Seedless vascular plants |
They have true roots, leaves, and stems, and their spore-producing structures permit wide dispersal. They also have a vascular system composed of xylem and phloem, allowing the movement of water and solutes. |
Ferns |
|
Gymnosperms (nonflowering seed plants) |
They do not produce a seed within a protective structure of a fruit and are wind pollinated and most (all except one species) have separate male and female reproductive structures called cones. |
Conifers |
|
Angiosperms (flowering seed plants) |
They have their seeds enclosed in a fruit and they are vascular plants. |
Fruits and vegetables |
Taxonomy
Taxonomy is derived from two Greek words taxis, meaning order, and nomos, meaning rule. The system of naming and categorizing flora, fauna, and microorganisms is known as taxonomy. Taxonomists identify and classify species using observations of their morphology, behaviour, genetics, and biochemistry. It is estimated that between 10 and 15 million species have evolved on Earth but taxonomists have only identified 1.78 million species of plants, animals, and microorganisms to date. Taxonomy is not limited to just biology but it has been developed in other practical fields also such as computing.
