Scientific Classification in Biology
Classification in biology, is the identification, naming, and grouping of
organisms into a formal system. The vast numbers of living forms are named
and arranged in an orderly manner so that biologists all over the world can
be sure they know the exact organism that is being examined and discussed.
Groups of organisms must be defined by the selection of important
characteristics, or shared traits, that make the members of each group
similar to one another and unlike members of other groups. Modern
classification schemes also attempt to place groups into categories that
will reflect an understanding of the evolutionary processes underlying the
similarities and differences among organisms. Such categories form a kind
of pyramid, or hierarchy, in which the different levels should represent
the different degrees of evolutionary relationship. The hierarchy extends
upward from several million species, each made up of individual organisms
that are closely related, to a few kingdoms, each containing large
assemblages of organisms, many of which are only distantly related.
Carolus Linnaeus is probably the single most dominant figure in systematic
classification. Born in 1707, he had a mind that was orderly to the extreme.
People sent him plants from all over the world, and he would devise a way
to relate them. At the age of thirty-two he was the author of fourteen
botanical works. His two most famous were Genera Plantarum, developing an
artificial sexual system, and Species Plantarum, a famous work where he
named and classified every plant known to him, and for the first time gave
each plant a binomial. This binomial system was a vast improvement over
some of the old descri...

...ly and structurally too dissimilar to the species
categorized above to fit into that scheme of taxonomy.
Although this system is complex and intricate at times, its
universality makes it a necessity. With out the system presently in use the
world would be years and years behind in their task to name all of the
living organisms on earth. This system is great but it is always possible
that some new finding could cause the system to evolve to become more
inclusive. This system is by no means set in stone, and Linnaeus would
probably be astounded to see the way that it has evolved since his original
system.

He was one of the leading scientists of his day in America. He tried new ways of planting crops and raising animals, (Greene 37). He was one of the first farmers to grow tomatoes in the United States, (Greene 25).
Thomas Jefferson one of our founding fathers was very interested in gardening and learning about the soil and land conditions. It has been written that he has grown over 300 varieties of vegetables and herbs and even over a hundred different kinds of fruits.

In the day that the LORD God made the earth and the heavens, when no plant of the field was yet in the earth and no herb of the field had yet sprung up - for the LORD God had not caused it to rain upon the earth, and there was no one to till the ground; but a stream would rise from the earth, and water the whole face of the ground - t...

Morgan played on Danny, was, they gave gave him a bud in the beginning. That day, he told his plant a joke and watered it. The next day, his plant had branched out! He did the exact same thing thing he had done the day before. Watered it and told it a joke. When he woke up the next morning it got even larger. Danny was getting more and more excited each day the plant grew more, which meant Danny’s mom’s trick was working! By the third night, Danny’s mom suggested they should put the plant outside. He ran outside the next morning only to see that his plant had grown into a flower bush! He took plenty pictures to show his class. After he had gone to school and showed the pictures to his classmates, Mr.Morgan took the class outside. Danny saw all his plant, he also saw the ones he had on each day! To his surprise, his mom popped out from behind the bush. They told him about their plan. Danny was not mad at his mom, and he still got the last laugh. He also got the new music tape that he was owed. Danny should’ve done some research, because the article “Probing Question: Does talking to plants help them grow?” states that “ people would have to speak to their plants for at least several hours a day to enhance photosynthesis enough to influence plant growth”. He could have figured out his was all a

The National Mental Health Commission makes 10 recommendations, including reducing the use of restraint, seclusion and involuntary treatments. Recommendation 6 states, “There must be the same national commitment to safety and quality of care for mental health services as there is for general health services.”
