Cell Theory

Good Essays
The debate between whether a virus is living or nonliving has been going on for years. In order to answer this question, one must have background knowledge relating to the current cell theory, the differences between prokaryotes and eukaryotes, and the structures and functions found within cells. Once this knowledge is known, a person is then able to give their opinion in the debate.
In the 1800s, the cell theory was developed. This theory states that cells are found in all living things making them the basic units of life and that all cells come from other cells. In order to be classified as a cell, the object in question must be able to reproduce, respond to chemical signals, obtain energy, maintain homeostasis, and undergo evolution. All cells can be divided into two different categories: prokaryotes or eukaryotes. Bacteria and archaea are classified as prokaryotes while animals and plants are eukaryotes. Prokaryotes are small and unicellular. Due to their small size, they do not have

Typically in biology, structure is synonymous with the word organelle. The word function relates to the role of each individual organelle of a cell. Each component of a cell has a job that it completes in order to keep the organism functioning. Two major components of cells are the ribosomes and the cell membrane. Ribosomes are found in both eukaryotes and prokaryotes. Although the location of the ribosomes vary between prokaryotes and eukaryotes, the structure and function are the same. Ribosomes are made up of a large and small subunit. These subunits contain rRNA and smaller protein molecules that work to synthesize protein. Along with ribosomes, eukaryotes and prokaryotes have a cell membrane. The cell membrane acts as a barrier between the cell and the outside environment. This barrier controls what materials enter and leave the cell. These two organelles are significant components to maintaining a

    Cells are the basic functional units of all organisms. Cells are the smallest unit of life and are often called the "building blocks of life". The distinction between prokaryotes and eukaryotes is considered to be the most important variation among groups of organisms. Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. The differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA. In this lab four cells were observed and they were Onion Epidermis Cell stained with Iodine, Elodea Freshwater Plant Cell, Epithelial Cells aka Human Cheek cells stained with Crystal Violet, and Unknown Cell. The difference between animal and plants cells is that animal cells does not have a cell wall or chloroplasts but plant cells do. Animal cells are round and irregular in shape while plant cells have fixed, rectangular shapes. Plant cells contains a large and central vacuoles while animal cells contains small and fewer vacuoles.…

    Because of virus’s parasitic characteristics, or the fact that they depend on host cells to “come alive,” viruses may be viewed as having a certain potential for life, which can be destroyed, but they cannot reach a more independent state of being. Viruses are not by themselves alive; however, they verge on life.…

    Technology has had a profound impact on the development of cell theory, allowing scientists to view the components of organisms on an unprecedentedly small scale. Before the creation of microscopes, misconceptions about how organisms were originated arose. The idea of spontaneous generation, a theory held for nearly two millennia, proposed that organisms originated from inorganic matter. The lack of technology impeded on the development of cell theory, until the creation of the microscope.…

    The CELL THEORY, or cell doctrine, states that all organisms are composed of similar units of organization, called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin's theory of evolution (1859), Mendel's laws of inheritance (1865), and the establishment of comparative biochemistry (1940).…

    Are Viruses Alive

    For many years there have been numerous controversies over whether a virus should be classified as living or nonliving. It is believed that viruses are considered nonliving because they lack a substantial amount of qualities to be classified a form of life and they are incapable of carrying out all life processes. For example, some characteristics that would justify a virus being nonliving would be that they are acellular: they are not made up of cells nor do they contain any cells, they do not have the ability to reproduce independently, and finally they are dead or inactive without invading a host cell because a host cell is what gives a virus the ability to have obtain many more characteristics of having life.…
