Monocot

A monocot is a group of flowering plants belonging to the class liliopsida of angiosperms, which are characterized by having only one cotyledon in the seed. The number of flower parts are in multiples of three along with having the vascular system arranged by xylem and phloem in paired bundles, which are dispersed throughout the stem. Another key characteristic of monocots are that the leaves usually have paralleled veins. This picture is the frog laying on grass which is a monocot and can be distinctly seen with having parallel veins if looked at closely.
