Cells Research Assignment I. Define the following terms CELL NOUN The (usually) microscopic structure, known as a cell. Is the functional and biological unit of all organisms (life forms). INFERENCE NOUN Is a conclusion, idea and/or opinion that is reached on evidence, reasoning and the information that you have. It is simply, an educated guess. Synonyms implication, interpretation, deduction, reasoning, speculation, presumption, assumption. OBSERVATION NOUN 1. An act of viewing,…

scientists had discovered a way to genetically reprogram mouse mature cells to convert them into a cell that has embryonic stem cell properties and these cells were named ‘induced pluripotent stem cells’ although it is still undetermined whether this new stem cell and embryonic stem cells are critically different. Human induced pluripotent stem cells were developed a year later in 2007. Scientists are optimistic about these stem cells and they are now being used within drug development and there…

Mitosis and Cancerous Cells Introduction Mitosis is by definition, “A type of cell division that results in two daughter cells each having the same number of chromosomes as the parent nucleus, typical of ordinary tissue growth.” Mitosis is a vital process to living organisms. Without mitosis, organisms could not grow, age, repair, or exist in general. Therefore, it is very important that the cell cycle is carefully controlled by the cell. This refers to is the limits set on cell division to…

A new and highly talked about topic is stem cell research. Stem cell research is an extraordinary, yet very controversial subject. Stem cells are a very large focus in today’s study of biomedical research. Stem cell research is beneficial because the research that is done can help cure diseases and regenerate cells that will be able to give humans, and their body’s, another chance at being healthy. Stem cells are defined as, “Undifferentiated cells of a multicellular organism that are…

oligotrophic environments. Their dimorphic cell cycle produces two morphologically and functionally different daughter cells, known as the stalked cell and the swarmer cell. The stalked cell remains anchored to the substratum and is sessile, while the swarmer cell is motile. Upon chemotaxis, the swarmer cell disperses in search of nutrients. Once sufficient nutrients are located the cell cycle can continue. In the early phases of the cell cycle, the swarmer cell will lose its flagella and begin…

chanted Captain Xerox at headquarters, and with that our micro-V96 craft was propelled towards the cell membrane for the first leg of our journey to investigate the process of Protein Synthesis in a eukaryotic animal cell. The cell membrane is a delicate wall of phospholipid molecules, consisting of hydrophilic heads and hydrophobic tails that swayed and looked like a mosaic. Our craft could not enter the cell directly through the semi-permeable membrane as it consisted of a negatively charged…

Despite the incredible diversity of cells that exist on our planet, they all have a common origin. Whether a red blood cell, muscle, or brain cell, all begin as a stem cell. These stem cells have become both a source of great potential for medical advancement as well as a hotbed of controversy. (Health, Stem Cell Basics, 2016) There are two different types of stem cells, embryonic stem cells and adult stem cells. Although embryonic stem cells are the ones most commonly heard about, both have…

Meiosis starts: DNA Replicates I am going to draw a nucleus with DNA inside it represented with beads as the four pairs of chromosomes. Outside of the nucleus there will be centrioles drawn. This is where meiosis begins and replicates the cell Spindle fibers start to form on the centrioles and chromosome pairs bind together making tetrads. Nuclear membrane starts to dissolve. Nuclear membrane will be drawn in dashed lines. The chromosomes will be homologous pairs with centromere in the center…

As we all know and have been studying as scientist that the cell is the basic unit of life. The cell provides structure for the body, takes in nutrients from food, convert those nutrients to energy and carries out specialized functions. The cell is composed of many parts, all with different functions. The cell is made up of two major parts which include the nucleus and the cytoplasm. The nucleus is surrounded by a nuclear envelope, which can also be referred to as the nuclear membrane which is…

Stem Cell Research Paper: Human Embryonic Stem Cells or (hESCs) Human Embryonic Stem Cells or (hESCs) are taken from human embryos, however these embryos are not normal ones. The (hESC) are embryos that were fertilized in a process known as in vitro fertilization. In vitro fertilization is usually done in a clinic of some sort and are then given to researchers for research with permission from the people who have donated. The human embryonic stem cells are not created from a woman, they are…
