Botany is the study of plants. The kingdom Plantae is divided into divisions (the term "division" was traditionally used instead of "phylum" as in the animals, but either term is now accepted).
Of these, the best known to most people are Bryophyta (mosses), Pterophyta (ferns), Coniferophyta (conifers), which are cone-bearing plants, and Anthophyta (angiosperms), which are flowering plants. Angiosperms are divided into two groups, dicots and monocots. Dicots have two cotyledons (embroyonic leaves), while monocots have only one cotyledon.
The names "Pinophyta" and "Magnoliophyta" are often used for "Coniferophyta" and "Anthophyta". Likewise, the monocots and dicots are called "Liliopsida" and "Magnoliopsida" respectively.
