- The major functions of the cell is concentrated at the outer edges of the retina and are used in peripheral vision. On average‚ there are about 125 million rod cells in the human retina. Rod cells are almost entirely responsible for night vision. Rod cells do not process fine details or color differences‚ but are highly sensitive to light. A single flash of light is all that is require to produce a response from a rod cell. Rod cells function as specialized neurons that convert visual stimuli in

Cells‚ in a lot of ways‚ are like factories. All the parts of a cell work together to accomplish common goals‚ just like parts of a factory. Each part also has a specific function‚ to make getting the job done a lot easier. The floor of a factory is a lot like the cytoplasm in a cell. It kind of keeps everything where it needs to be‚ and helps direct organelles around the cell‚ much like the pathways on the floor around the machines. The cell membrane in a cell is very similar to the outside

doctors in the 1950’s‚ cells from her tumor were sent for research without her consent; and unfortunately the credit/rights that her and her family deserves have been thrown in the air. Medical procedures of the 1950s and 60s caused people to question if what was being done was moral or ethical for the family. Upon observation of the arguments made by the people and the scientific community‚ it is simple to see the fine line that people’s views may be approaching. HeLa (cells of Henrietta Lacks) have

Cell: The cell is the basic structural‚ functional and biological unit of all known living organisms. Cells are the smallest unit of life that is classified as a living thing‚ and are often called the "building blocks of life". Discoverer: The cell was discovered by Robert Hooke in 1665. The cell theory‚ first developed in 1839 by Matthias Jakob Schleiden andTheodor Schwann‚ states that all organisms are composed of one or more cells‚ that all cells come from preexisting cells‚ that vital functions

Why is Vitamin C good for you? Health The most well-known health benefit of blackcurrants is that they contain large amounts of Vitamin C. Vitamins are substances we need to enable our bodies to live‚ grow and reproduce normally. Vitamin C is an essential nutrient - it cannot be made by the human body and we must therefore eat foods which contain it (Bibliography Ref: 13). Because the body breaks down Vitamin C very quickly and does not store very much‚ we need to eat Vitamin C containing foods

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;

biology‚ cell theory is a scientific theory that describes the properties of cells‚ which are the basic unit of structure in all organisms and also the basic unit of reproduction. The initial development of the theory‚ during the mid-17th century‚ was made possible by advances in microscopy; the study of cells is called cell biology. Cell theory is one of the foundations of biology.The observations of Hooke‚ Leeuwenhoek‚ Schleiden‚ Schwann‚ Virchow‚ and others led to the development of the cell theory
