Botanist, place most angiosperms within two groups: monocots(1 leaf), and dicots(2 leaves) (referencing to the first leaves on the plant embryo) The embryonic leaves are called seed leaves, or cotyledons - majority of dicots are, called eudicots originate from the a common ancestor, with a few evolving independently. Large group of related plants including : orchids, bamboos, palms, lilies, grains and grasses. Parts of monocots: cotyledon(1 leaf, ), leaves (parallel veins), stem (vascular tissue to transport water and nutrients), flowers(petals in multiples of threes), and roots(most within the top few cm of soil, good ground cover). Include most flowering shrubs and trees. (majority of our ornamental plants, and food crops) - parts of the eudicot: cotyledon(2 leaves),
