Portfolio The Cell and Cell Theory [pic] The cell The word cell comes from the Latin word “cellula”‚ which means a small room. The cell is the smallest unit of a living organism‚ also known as “the building block of life”. Every living organism is consisted of a cell. There are bacteria (unicellular organisms)‚ and multicellular organisms. There are different types of cells‚ prokaryotic and eukaryotic cells. All cells come from preexisting cells. “Every cell is self-maintaining;

3. Why don’t the terms depolarization and action potential mean the same thing? The terms depolarization and action potential differ because are excitable cells that communicate by transmitting electrical impulses that are capable of producing rapid electrical signals and depolarization in the interior surface of the membrane which becomes less negative and the exterior surface becomes less positive. Additionally‚ when depolarization reaches a certain threshold‚ an action potential is initiated

and curious neighbours looked on. The car arrived at the station‚ the suspect was brought inside‚ formally booked‚ again warned of his Miranda rights‚ finger printed‚ and a complete identification was made. The suspect was then taken to a holding cell where he was left blindfolded to ponder his fate and wonder what he had done to get himself into this mess. Consider the police procedures which make arrestees feel confused‚ fearful‚ and dehumanized. Note that this policeman is wearing sunglasses

W2: Assignment 2 Lisa Majdecki South University Online THE ORGANELLES OF EUKARYOTIC CELLS . The difference between Prokaryotic and Eukaryotic Cells is organelles‚ membrane enclosed structures that perform specific duties. The most important of all is the “nucleus‚” this holds the DNA and is surrounded by a double membrane. The Prokaryotic lacks a nucleus which is not partitioned from the other cells by membranes. The region between the nucleus and plasma membrane is called

Controlled Assessment: Osmosis of a Potato [pic] Osmosis: Osmosis is the movement of substances through a partially/semi permeable membrane from an area of high concentration to an area of low concentration to balance of the concentration of the two sides. Biological membranes do allow water to pass through‚ but water will have no net movement unless osmosis takes place. Preliminary Method I have chosen to investigate the factor of the weight of potato strips after set amounts of time.

Animal Cells Vs. Plant Cells There are quite a few similarities and differences between plant and animal cells. Whether it be the internal parts of the cells‚ or the processes they go through. They also have differences in shape and sometimes size. These are only a few examples of similarities and differences between the two different cells. To begin with‚ both animal and plant cells are eukaryotic cells. This means that both cells have the same internal features‚ such as a cell membrane‚ a

I lived on a potato farm in Ireland during the Great Potato Famine. It was the worst famine in Europe in the 19th century. This famine started in September of 1845 and ended in 1852. During this time‚ life in Ireland was extremely difficult. We suffered from much starvation and disease. Approximately one million of us died and another million emigrated to other countries‚ especially America. The population of the country dropped 20 to 25%. The Great Famine began mysteriously.
