1 The study included the most common STDs: HPV, chlamydia, herpes simplex virus, and trichomoniasis. 2  There are approximately 15 million new cases of sexually transmitted infection each year in the United States, and 340 million worldwide.  The majority of STI's are asymptomatic (no symptoms).
Monocots have a trimerous flower, or a flower with parts in multiples of three. You can simply count the petals of a flower, and if you can divide the total number by three, you probably have a monocot. As you can see in this image of a lily, there are six petals in total, a multiple of three. Lilies are a type of monocot. In fact, many big, showy flowers like lilies, daffodils, bluebells, irises, orchids, and tulips are monocots. But flowers aren't the only way to recognize a monocot.
Monocot leaves have their leaf veins arranged parallel to each other and the long axis of the leaf (parallel vennation). An common example of this is the husk of corn or a blade of grass (both are monocots). Dicot leaves have an anastamosing network of veins arising from a mid-vein termed net vennation.onocot seeds have one seed leaf termed a cotyledon (in fact monocot is a shortening of monocotyledon). Dicots have two cotyledons. Both groups, however, have the same basic architecture of nodes, internodes, etc. Comparison of monocot (left, oat) and dicot (right, bean) gross anatomy.
