Makes up the bulk of the plant everything other than dermal and vascular tissue. Monocots and eudicots have the same tissues organized in different ways: Have one cotyledon (***seed leaf of embryo) Pollen grain has 1 pore flower is in multiple of 3 leaf veins usually parallel with one another. Eudicots include flowering shrubs and trees, vines, tomatoes and dandelions. Have two cotyledons (seed leaves of embryo) flower is in multiples of 4 or 5.
