Scientific Classification of Plants Taxonomy – the science of classifying and identifying organisms such as plants

Scientific Names Scientific names are necessary because the same common name is used for different plants Latin is the language used for scientific classification

Scientific Names Carlos Linnaeus is a Swedish botanist that developed the binomial system of naming plants by using two Latin words to indicate the genus and the species

Scientific Names In the scientific name, the first word is the genus (first letter is capitalized) Plants in the same genus have similar characteristics In the scientific name, the second word is the species Plants in the same species consistently produce plants of the same types If there are additional words after the species, they indicate the variety or cultivar (variety var or cultivated variety or cv)

Plant Kingdom The broadest category of scientific classification is the Kingdom (plant or animal) The broadest category of the plant Kingdom is Division or Phylum

The four most important divisions of the plant Kingdom are: Thallophytes – algae, fungi, lichens

The four most important divisions of the plant Kingdom are: Bryophytes – true mosses, liverworts

The four most important divisions of the plant Kingdom are: Pteriophytes – ferns, horsetails, club mosses

The four most important divisions of the plant Kingdom are: Spermatophytes – seed bearing or flowering plants Gymnosperms – seeds are not in an ovary (cone) Angiosperms – seeds are enclosed in an ovary (flowering)

Common Plant Genus Pinus – pine Acer – maple Ilex – holly Ficus – fig Cornus – dogwood Quercus - oak

Scientific Name Example White Oak’s genus and species would look like: Quercus alba
