Essays on Cell

Scientists and microscopists have known cell cycle and cell division for over hundred years. However, it was the pioneering and revolutionary work of Alma Howard and Stephen Pelc in the 1950s that revealed DNA replication took place at a particular phase of the cell cycle….

Nerve cells also are known as neurons transmit and receive electro nerve impulses. They can be found all over the body and are connected all over the body, but can mostly be found near around the Central Nervous System. They are connected to other neurons…

Heat shock proteins (HSPs) are highly conserved family known to be master regulator of thermal stress. Circulating leukocytes can be used as an effective model to understand response revealed by thermally stressed animals in tropical climate. Present investigation was aimed to evaluate comparative cellular tolerance…

Cross Market Compatibility The self charging battery for cell phones would be one of a kind battery used for commercial purposes and mostly in cell phones. The battery would be rechargeable without having to plug it in any electrical outlet. The product will apparently be…

The Secret Behind the Size of Cells For the Surface Area to Radius and the Volume to Radius graphs, the relation of the two components seemed to grow while the graph for the Surface Area to Volume ratio graph, the relations seemed to decline. The…

Eukaryotic cells are the most structurally advanced of the major cell types. One thing unique about plant cells is that they have chloroplasts. chloroplasts have a double-membrane envelope, called the chloroplasts envelope. Animal cell do not have chloroplasts. Chloroplasts in plant cells is where photosynthesis…

Summary A recent clinical research study concluded that up to 50% of all children diagnosed with sickle cell disease (anemia) are at risk of having a stroke (Dowling, et. al. 2012). The “decrease in oxygen delivery to the brain,” caused by sickle cell disease, puts…

Introduction Recently, I’ve wondered what the results of old experiments would look like today. My abiding question throughout the years has been, “How do hydras parcel out parental cells and mold them into buds?” I was asking the question back in 1979 when I gave…

Cold tolerance is the result of complex physiological phenomenon involving many cell and plant traits. Plants differ in their tolerance to chilling (0-15 ºC) and freezing (< 0ºC) temperatures. Different studies have indicated that the plasma membrane of the cell is the primary cause of...

The Discovery Of Hela Cells has drastically improved the science industry within only a few years after they were taken from Henrietta’s tumor and grown in culture. After Jonas Salk used HeLa to test the polio vaccine he created, the mass production of HeLa cells…
