Which of these branches deals with the naming and classifying of plants?

The science of botany is divided into branches. Which of these branches deals with the naming and classifying of plants?

Which of these branches deals with the naming and classifying of plants?
systematics and taxonomy





systematics is the study of the diversity of organism characteristics, especially how they relate evolutionarily thus establishing their phylogeny. and as a science, systematics deals with the relationships between taxa, especially at the higher levels.





taxonomy on the other hand, concerns itself with scientific classification of species and other taxa. and as a science, taxonomy deals with finding, describing and naming organisms.
Reply:There are more branches to botany than two but systematics/taxonomy are associated with classification. They are not strictly the same, though. Taxonomists are by definition, those who classify and name. Systematics is a wider field and a systematist might work on a specialized area like anatomy, chemistry, pollen morphology etc that will help improve classification but and might never name anything.
Reply:Plant taxonomy is the science that finds, describes, classifies and names plants. It thus is one of the main branches of taxonomy. Example for the Liliales order :





Kingdom: Plantae


Division: Magnoliophyta


Class: Liliopsida


Order: Liliales


Families : Liliaceae


There is no sharp boundary between "plant taxonomy" and "plant systematics", although in practice "plant systematics" will be involved with higher level relationships between plants (see history of plant systematics) rather than with the actual handling of plants (see herbarium). Plant taxonomy is wellknown for being turbulent, and traditionally there is no really close agreement on circumscription and placement of taxa. See the list of systems of plant taxonomy.
Reply:The plant kingdom divided into four divisions or phyla, according to their structural characteristics:





1. Thallophyta--these include the algae, bacteria, and fungi. Some taxonomists put the fungi in a separate division. The most familiar plants in this community are the mushrooms and bread molds. The thallophytes are not differentiated into stems and leaves and essentially have no protective covering for their reproductive cells.





2. Bryophyta--the small green plants without true roots or flowers. The name comes from the Greek word bryon, which means moss, and this division includes the mosses, liverworts, and hornworts. These are widely distributed over the earth, particularly in wet places, but are not generally cultivated for human use.





3. Pteridophyta--green plants with vascular tissue, true roots, and usually distinct leaves and stems. They do not have true flowers and, therefore, produce no seeds. They reproduce themselves by spores found on the underside of leaves. This group includes the psilophytes, club mosses, horsetails, and ferns. They are cultivated mainly as ornamentals.





4. Spermatophyta--seed-producing plants that bear true flowers. Practically all of the economically important plants used for food, feed, fiber, shelter or recreation belong to this phyllum.





Some taxonomists have expanded the four basic divisions (phylla) into as many as 28. Taxonomy, or the study of plant classification, is dynamic and changes often as new knowledge becomes available.
