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.
Monocots have only one cotyledon, dicots have two cotyledons. A cotyledon contains stored food and serves as a food reservoir. Aside from the difference between the seeds of monocots and dicots there are other different structures that separate monocots and dicots.Monocots have long, narrow leaves with parallel veins (such as grasses.) The parts of monocot flowers are arranged in threes or in multiples of three.Dicots have broad leaves with branched veins. The parts of dicot flowers are arranged in fours and fives or multiples of fours and fives.side from the difference between the seeds of monocots and dicots there are other different structures that separate monocots and dicots.
