The Amazing Cell Essay

There are many parts of a cell, they all have specific duties, and are all

Cell Theory is an explanation that says everything is made of cells. It continues on to say that those cells came from preexisting cells. Cell Theory is a theory because it is a frame-worked explanation of an observation made by many biologists like Anar Van Leeuwenhoek. Van Leeuwenoek studied plant stems, pond water, and gathered a conclusion that generally, all of those things are made of cells. Other biologists like Louis Pasteur added onto this idea that all organisms are composed of cells. A theory is also composed of two components; a sequence of patterns in the world and the thing or catalyst that is responsible for the pattern. The sequence of the pattern in Cell theory is that every organism in the world are made up of cells.

Much medical advancement would not have been possible without cancer cells from Henrietta Lacks. While these HeLa cells are infamous in the medical community, the story behind them was barely known by any until Rebecca Skloot uncovered it.1 Information about Henrietta Lacks uncovers a history of consent not being asked for, and certainly not being given, but because of the cells, medical discoveries were made without her family’s knowledge.1 It brings to light the idea that while cells are a part of a person’s body, once they are out of the human body there is no more ownership. Without informed consent though, is it still owned by the person whose cells they are?

You are a nurse who works in a busy A&E department in a city hospital. Because you are experienced and highly regarded your manager has asked you to mentor some new nurses who have just qualified.

This is the story of a cell, a young cell. This cell’s goal was to have the most powerful mitochondria of any other cell she knew. The mitochondria gave energy. She knew if she had a strong mitochondria, her being would be powerful and strong.

Without cell division and the cell cycle nearly all life would fail to exist. Cell division allows an organism to not only replace its own cells but to create offspring. The cell cycle consists of two main parts: interphase and mitotic phase. Within these two phases the processes can be broken down into further categories. Interphase can be broken down into three subphases that are the necessary preparations the cell makes in order to be ready to divide during mitosis. For this lab we looked mainly at the mitotic phase because of its fascinating and rapid changes to the cell. The cell types we looked at were prepared slides of whitefish and onion root tip.

17) The process by which the cytoplasm of a eukaryotic cell divides to produce two cells is called

Merriam Webster defines an abstraction as “a general idea or quality rather than an actual person.” Humans are immensely complex creatures who cannot be confined to stereotypes, classifications or labels. Each person is equipped with their own set of traits, talents and capabilities that make them who they are. Viewing a person as simply an abstraction restricts them to a category stating who and what they are allowed to be effectively taking away the uniqueness each and every person has a right to. Both the scientific community and the media are guilty of viewing Henrietta in this way, these individuals exploited her cells without expressed consent for their own personal gain, told her story only when it was convenient for them, and never

cell will look just like any other 'normal' cell although this is far from the

Mitosis is one of two main methods of cell replication, the other being meiosis. It is “the simple duplication of a cell and all of its parts” resulting from the splitting of a cell. The ‘parent’ or original cell splits, duplicating its DNA (packaged in chromosomes) producing two ‘daughter’ or new cells with the same genetic code. There are four stages of mitosis; Prophase, Metaphase, Anaphase and Telophase. Interphase is not an official phase of mitosis as the cell is at ‘rest’ and not being divided during this phase. It is often called one of the phases of mitosis as it is one of the stages in the life cycle of a cell; however it is not a phase of mitosis due to the fact that no division takes place.

The society has evolved over the decades. Medical advances, greater technologies, better understanding of the world around us, the sky is the limit! The progression of a society is astounding from where it was just twenty years ago. One is able to do things that the forefathers would have never dreamed! Science has discovered ways to travel to the moon and back, reach some of the deepest depths of the oceans and discover new species, and drive hybrid cars. The achievements of today’s society have reached a new high; however, with great achievement comes great questions of ethics.

The HeLa cell lines emerged, on February 1, 1951, after a woman by the name of Henrietta Lacks visited her physician after noticing blood spots in her underwear. The physician examined Henriette and discovered a tumor in her cervix. The physician retrieved a segment of the tumor and sent it to a lab for further diagnosis. Later on, it was announced that the tumor was infectious. Days later Henrietta returned to her physician and another sample was taken and sent to the head of tissue culture research at Hopkins, George Gey. Both Gey and his were in the search for a tool that specialized in the study of cancer. If their innovation succeeded they could reveal a treatment for cancer. During Gey’s research of Henrietta’s cells multiplied rapidly and within days the cells increased in thickness. Henriett Lack died October 4, 1951. George Gey main

Cells share many common features but have adapted over billions of years in a wide array of environments, to provide a variety of functional roles.

Across the planet, four times every second, a new human is conceived. In just nine months, a single cell no bigger than a speck of dust transforms into the most complex organism on earth. There are many events that shape and define us long before we’re born. Right from the start, it’s a journey full of surprises. There are many things that make you who you are today.

Nucleus- “the brain” or control center of the cell. The Nucleus, a membrane-bound structure of a cell, plays two crucial roles in controlling the cell. The nucleus carries the cell's genetic information that determines if the organism will develop, for instance, into a tree or a human; and it directs most cell activities including growth, metabolism, and reproduction by controlling protein synthesis. The presence of a nucleus distinguishes the more complex eukaryotic cells of plants and animals from the simpler prokaryotic cells of bacteria and cyanobacteria that lack a nucleus. The nucleus is the most predominate structure in the cell. It is typically round and occupies 10% of the cells total volume. The nucleus is wrapped in a
