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.
Another important difference is that while in monocots the flowers have petals in multiples of three, in the case of dicot these are in multiples of 4 or 5. As far as the leaves are concerned, monocots exhibit parallel veins while dicots have reticulated veins. There are many other features that distinguish the two.nother important difference is that while in monocots the flowers have petals in multiples of three, in the case of dicot these are in multiples of 4 or 5.
