Diverrsity of Plants Diverrsity of Plants Diverrsity of Plants Plants evolved more than 430 million years ago from multicellular green algae. By 300 million years ago, trees had evolved and formed forests, within which the diversification of vertebrates, insects, and fungi occurred. Roughly 266,000 species of plants are now living. The two major groups of plants are the bryophytes and the vascular plants; the latter group consists of nine divisions that have living members. Bryophytes and ferns require free water s
Down Syndrome: An Informative Essay Down Syndrome: An Informative Essay Down Syndrome: An Informative Essay Down Syndrome is the name for babies born with a disorder related to their chromosomes. It is caused when meiosis occurs and an error occurs in the cells development. The reason for this defect is often because the parent is over 40 or for some other reason their meiosis is not Up to par. The actual defect is an extra chromosome is developed during cell development. The abnormal development results in 47 chromosomes rathe
The Future of Human Evolution The Future of Human Evolution The Future of Human Evolution Alexander R. Prof. Kohn Darwinism and Evolution 12-6-96 Evolution, the science of how populations of living organisms change over time in response to their environment, is the central unifying theme in biology today. Evolution was first explored in its semi-modern form in Charles Darwin \'s 1859 book, Origin of Species by means of Natural Selection. In this book, Darwin laid out a strong argument for evolution. He postulated that all s
Genetic Observations Through The Studies of Hybrid Genetic Observations Through The Studies of Hybrid Corn, Single Gene Human Traits, and Fruit Flies Genetic Observations Through The Studies of Hybrid Corn, Single Gene Human Traits, and Fruit Flies The basic foundation of modern genetics was led by Gregor Mendel (Corcos, 1993). Mendel was not the first to experiment with heredity, and our Lyman Briggs biology class will not be the last to deal with genetics. Genetics is the science of heredity. In our lab, we had three main objectives. First, w
Gregor Mendel's Theories of Genetic Inheritance Gregor Mendel\'s Theories of Genetic Inheritance Gregor Mendel\'s Theories of Genetic Inheritance Gregor Mendel played a huge role in the underlying principles of genetic inheritance. He grew up in a Augustinian brotherhood where he learned agricultural training with basic education. He then went on to the Olmutz Philisophical Institute and then entered the Augustinian Monestary in 1843. After 3 years of theological studies, Mendel went to the University of Vienna where he was influenced by 2 p
Cell division cell division Word Count: 434 Cell Division Why must cells divide? To start it off, cells canít keep growing forever, so when they reach a certain size they will have to divide. Cells divide for four important reasons; reproduction, growth, repair, and replacement of damaged or worn out cells. Most cells divide at least once during their life cycle and some divide divide dozens of time times before they die. There are three types of cell division. They are binary fission, mitosis, and meiosis.
Gregor Mendel Gregor Mendel Word Count: 559 Gregor Mendel played a huge role in the underlying principles of genetic inheritance. Gregor was born, July 22 1822 in Heinzendorf, Austrian Silesia (now known as Hyncice, Czech Republic), with the name Johann Mendel. He changed his name to Gregor in 1843. He grew up in an Augustinian brotherhood and he learned agricultural training with basic education. He then went on to the Olmutz Philosophical Institute and later entered the Augustinian Monastery in 1843. After
Biology Biology Biology 1. The virus is made up of five parts and is in the size range of 10 nm-300 nm in diameter. The first is the coat made up of protein that protects the virus to a point. Next is the head that contains the genetic material for the virus. The genetic material for a virus is DNA. The two other parts are the tail sheath and the tail fibers that are used for odd jobs. I believe that a virus is not considered to be a living creature due to the fact it is a parasitic reproducer. To me i
