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.
The monocot is the plant that has only one cotyledon in the embryo, whereas dicot is the plant that has two cotyledons in the embryo. Monocots and dicots differ from each other in four structures: leaves, stems, roots and flowers. Here weâll be differentiating it between the stem of the monocot and dicot plant. The major difference between stems of both the plants is due to the arrangement of the vascular bundle.
