Cells: from Earthlings to Martians

Daniel Petrov 8e Cells From Earthlings to Martians? Mr F. Ade-Davis Science Our model of the cell unquestionable from a lot of steady-going scientists such as Robert Hooke and many a(prenominal) separates. Robert Hooke observe cells when he looked at a slice of cork in a microscope. And he had withal demonstrate out that it was made of many petty cells. Furthermore, a Dutch scientist had discove ruddy a large variety of red blood cells and sperm cells and egg cells. Cells be the basic building blocks of in all living things.A cell is aboutthing really tiny that could non be seen with a naked eye but only using a microscope. They also take in nutrients, convert these nutrients into energy, carry out specialized functions, and regorge as necessary. Cells hold back many parts that all(prenominal) do a large variety of different things. Some of the things a cell contains is a cytoplasm and a lens nucleus. A cytoplasm is a jelly- equal fluid that surrounds the nucleus and a nucleus controls the activities that the whole cell does.Cells also act unneurotic to form and create everything that exists in this world today. One type of cells ar known as Bacteria cells. Bacteria were among the first support forms to start onEarth, and are present in mosthabitatson the planet, suppuration in soil, water,acidic hot springs, radioactive wasteland and deep in theEarths crust, as well as in organic matter and the zippy bodies of plants and animals. The vast majority of the bacteria in the body are rendered innocuous by the protective effects of theimmune system, and a few arebeneficial.However, a few species of bacteria arepathogenicand could cause some serious infectious diseases, includingcholera,syphilis,anthrax,leprosy, andbubonic plague. They contain a well authenticcellstructure. Bacterial cells are fairly small cells that come in many different types such as spheres, rods and spirals. Bacteria cells do non take a crap a nucleus unlike early all o f the other(a) cells. They also contain a cell wall, cyptoplasm, a cell tissue layer and Free DNA.A meteorite had been found on mars that contained many un plebeian things and forms of life inside it. The objects in the mars meteorite could have been either cells , unknown animals or even Martians. The evidence for this information being true could be that when scientists had examined the tall(a) rock , the gas trapped inside it matched the atmosphere on mars. Also, the rocks that rowlock on earth every day are not usual types of rocks, but rocks that are often very hard to be recognized. Scientists could and hould tract their findings with other scientists so they can link the things that they have found out. By sharing your findings, not only would they learn new and interesting things from each other, but they would also see if the information is correct and very accurate. Furthermore, look review could be a good thing to do because wad would learn a great deal about their writing, they get good feedback from fellow scientists and they are able to improve their findings by using other peoples information.On the other hand, peer review could not be such a positive but a negative thing because they could not like for other people to see their findings and work, or the information given could not have strengths but weaknesses. In conclusion, I personally think that the objects and gasses found inside the meteorite could be real because scientists have observed the rock and have also found out that gasses the rock contained matched the whole of the atmosphere on Mars.Also, peer review is a good thing to do because you partake you findings with other scientists and get positive feed back and how you could improve the things you have found out by being more accurate. This also cogitate to the development of cells because Robert Hooke had found out that the strip of cork he was sight using the microscope contained and was made up of many small cells, and he had divided this with many the other scientists and thats how the understanding of the cell has been improved through these many years.
