The most basic division of living plants is between nonvascular and vascular plants. How do you know which group one particular plant belongs to? Classification of Plants The scientific classification of modern land plants is under constant revision. Major Division Types of Plants No. They have no stems, so they grow low to the ground.
They reproduce with spores. They need a moist habitat. Vascular Plants Clubmosses 1, They have roots and tiny leaves. Ferns 11, They have large leaves in fronds.
They have stiff stems, so they are tall growing; some are trees. Ginkgoes 1 Cycads Conifers Gnetae 70 Most are trees with wood trunks. Are there any other ways you might have classified the types of plants? Save my name, email, and website in this browser for the next time I comment.

This phylum include the mosses, liverworts, and hornworts. Among all plant phyla, the members of the Phylum Bryophyta are considered the simplest.
Regarding physical appearance, mosses are small and inconspicuous. Bryophytes lack vascular tissue and wood that can render them structural support.
They also lack true leaves, stems, and roots that can help them transport water and nutrients. Because of this, they are limited to a narrow range of habitats.
Despite lacking some essential plant organs, bryophytes play an important role in minimizing erosion along bodies of water, carrying out water and nutrient cycling in forests, and regulating temperature in permafrost. Also see the biological weathering article. Regarding habitats and physical structures, bryophytes are related to lichens [3] symbiotic relationship between a fungus and algae. For instance, both of them utilize the moisture in the environment to transport minerals and nutrients.
Because of that, bryophytes live in moist places and somehow have adapted several methods that can help them thrive in dry periods. The use of the genus and species names together always refer to only one plant.
The species name is written after the genus and is never capitalized. Example: Rudbeckia hirta X. Variety Not used with all species. To receive this added piece of nomenclature, a plant must be only slightly different from a certain species, but not different enough to be granted its own species name.
When used, the Variety name follows the Genus and Species names with the abbreviation, "var," followed by the full variety name in small letters. The wildflower Scarlet Flax is a good example: Linum grandiflorum var rubrum. In Latin, this tells you that this is a Flax linum with large flowers grandiflorum that happen be red rubrum. Most of the family is not red-flowered. Most wildflowers do not have this extra little added-on name, for example, Rudbeckia hirta does not.
Planting Information. About Us. Compare Products. Teaching Standards. Big Ideas Plants must be classified into identifiable groups in order for us to have a clear, organized way of identifying the diverse array of plants that inhabit the planet. Essential Questions How are plants categorized into groups?
What are the characteristics of plants that are used to classify them? Content Outcomes Addressed Students will be able to understand the purpose and importance of classification. Students will be able to perform simple classification of plants and to justify their reasoning by pointing to defining plant characteristics e.
Students will be able to compare and contrast plants species and to identify specific characteristics that distinguish one plant group from another. D K-2 , LS1. A K-2 , LS4. A1, 2 MD. A3 National Geography Standards: 2, 7, 8. Example of Plant Classification.
