All the different kinds of plants belong to the kingdom Plantae. They are divided into two groups depending on whether they are seed-bearing plants or plants without seeds. Plants are also classified by their genera, families, and species. This type of plant classification allows for easy identification of plants and makes them easier to study.
Plants classifications also depend on their vascular system. Non-vascular plants such as algae are primitive plants or in a lower class of plants and have simple tissue systems to transport water internally. Vascular plants such as shrubs, trees, herbs, and flowering plants have complex vascular tissue to transport fluid and nutrients internally.
The Main Kinds of Plants
All the different types of plants are classified into two main groups: plants without seeds and plants with seeds.
Plants without seeds are algae, mosses, ferns, and liverworts. These unique plant types produce spores that are distributed by the wind. For example, if you look at the underneath of fern leaves, you will notice sporangia which are tiny structures containing spores.
Plants with seeds are all kinds of flowering plants, cycads (palm-like plants with cones), conifers (such as spruce, firs, pines, junipers and cedars), and ginko.
Flowering plants produce seeds that are protected within their fruit. These fruits can be soft fruits such as apples, oranges, or berries, or they can be hard like all types of nuts.
Plants with cones, mostly evergreen trees, are another kind of vascular plants with seeds.
