Crupina vulgaris Crupina vulgaris is a class A federal noxious weed under the asteraceae family and dicot group, and is part of the spermatophyta subdivision that produces seeds (Natural Resources Conservation Service 2016). C. vulgaris is commonly known as Bearded creeper or Common crupina. It is a winter annual weed that can grow 1 m or 1 to four feet tall (Crupina vulgaris 2015) with three sterile and two fertile flowers (Crupina vulgaris (bearded creeper) 2011) pink to purple in color. C.…

hundred tightly coiled tubules lined with germs cells. These tubules serve as the site of sperm production. Inside of these tubules spermatogonia progress to spermatocytes, then spermatids, and finally sperm. Also inside, sustentacular cells serve as a means of support. These cells control the environment by removing wastes, providing nutrients, and providing antibody protection as well as regulating sperm production. Interstitial cells outside of the tubules secrete testosterone and stimulates…

A. Size and Structure - sperm, the smallest cell within the human body, are only a few micrometers long. It is composed of a head, midpiece, and tail. Within the head are the nucleus, condensed DNA containing 23 chromosomes, and the acrosome. The acrosome is located at the end of the head and is considered a modified lysozome containing digestive enzymes that are capable of breaking through the outer layer of an egg. The midpiece of the sperm contains mitochondria that produce the energy for the…

to find and get rid of diseases of the parent’s babies. Throughout the years scientists have used IVF and PGD for more physical and characteristical traits like blond hair or blue eyes. During the process ofTo do IVF, scientists combine the egg and sperms provided to form an embryo, take an embryo and an egg with a petri dish, engage in tests, and then puts the fertilized egg inside the mother. The outcome or the end result is known as a designer baby, a child that is or has went through the IVF…

Hibiscus rosa-sinensis is the scientific name for Hibiscus. Other places around the word may call it Chinese hibiscus, China-rosa, and Hawaiian hibiscus (USDA, ARS, National Genetic Resources Program). Hibiscus is native to East Asia, but may be seen in numerous places. It is widely cultivate around the world. Hibiscus rosa-sinensis came from the scientific classification: Kingdom is Plantae; unranked are Angiosperms, Eudicots, and Rosids; Order is Malvales; Family is Malvaceae; Genus is…

Summary Heat stress has shown to be detrimental to male reproduction, affecting the testicles and spermatogenesis. In 2010, a study was conducted in Iran using male lambs which were exposed to chronic heat stress. The objective of the study was to investigate the effect of moderate and high temperatures on testicular structures and on testosterone and cortisol concentrations in the developing ram lambs. Twenty fall born ram lambs were randomly assigned to a group: either to an outdoor heat…

normal supply blood to the reproductive glands inside the scrotum that is the sack of skin that holds the testicles. This type is disorder leads to blockage of blood, which is the main cause of male infertility since it leads to reduced sperm quality and also less sperm production. It is treatable and heals permanently especially after the use of natural products. These products have very minor/ no side effects which can be managed in case they occur. Normally, if you have veins inside the…

The sperm cell makes it journey through the body to make it to the egg. This article discus the journey this sperm cell will make to get to the egg to fertilize it. It starts with talking about the cell and how it works. As it says in the article “The sperm starts out as a round, immobile cell. An important structure, the "acrosomal body," that will eventually develop highly erosive enzymes--able to dissolve the membranes around other cells--is made by Sertoli cells at the newly-developed head…

its Arrival to the Egg Before embarking in the complexity of CatSper channels, the particular characteristics of sperm and its movement towards the egg in female that allows for fertilization should be addressed. Spermatozoa are differentiated motile cells that have two main structures: the head, which houses packed DNA, and the flagellum, the motility portion that transports the sperm genetic information to the egg (1). Within the spermatozoa head both a vesicle which covers the head, known as…

Introduction I chose to write about the most versatile animal that I can think of, the coyote! The coyote is a native to my original home, Wisconsin and to my current home, Colorado! The coyote is a mammal, just like us! This being said, they are many similarities in the make up of this animal! Coyote They coyote comes from the classification of eukaryote. From the “root” of the branch, comes both animals and plants. Animals and plants are sister taxa, meaning that they branch off from eukaryote…
