Intermediate minor rankings are not shown. In biology, a kingdom is the second highest taxonomic rank, just below domain. Kingdoms are divided into smaller groups called phyla (singular phylum). Traditionally, some textbooks from the United States and Canada used a system of six kingdoms ( Animalia, Plantae, Fungi, Protista, Archaea ...
Grain, fruit, and vegetables are basic human foods and have been domesticated for millennia. People use plants for many purposes, such as building materials, ornaments, writing materials, and, in great variety, for medicines. The scientific study of plants is known as botany, a branch of biology .
Plant taxonomy. Plant taxonomy is the science that finds, identifies, describes, classifies, and names plants. It is one of the main branches of taxonomy (the science that finds, describes, classifies, and names living things). Plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two.
A kingdom contains one or more phyla. Intermediate minor rankings are not shown. In biology, a phylum ( / ˈfaɪləm /; pl.: phyla) is a level of classification or taxonomic rank below kingdom and above class. Traditionally, in botany the term division has been used instead of phylum, although the International Code of Nomenclature for algae ...
The Archaeplastida (or kingdom Plantae sensu lato "in a broad sense"; pronounced / ɑːrkɪˈplæstɪdə /) are a major group of eukaryotes, comprising the photoautotrophic red algae (Rhodophyta), green algae, land plants, and the minor group glaucophytes. [ 6] It also includes the non-photosynthetic lineage Rhodelphidia, a predatorial ...
Cycads / ˈsaɪkædz / are seed plants that typically have a stout and woody ( ligneous) trunk with a crown of large, hard, stiff, evergreen and (usually) pinnate leaves. The species are dioecious, that is, individual plants of a species are either male or female. Cycads vary in size from having trunks only a few centimeters to several meters tall.
Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae. Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the ...
Metaphyta Whittaker, 1969[ 10] Plantae Margulis, 1971[ 11] The embryophytes ( / ˈɛmbriəˌfaɪts /) are a clade of plants, also known as Embryophyta ( / ˌɛmbriˈɒfətə, - oʊˈfaɪtə /) or land plants. They are the most familiar group of photoautotrophs that make up the vegetation on Earth 's dry lands and wetlands.
