"Little Mito"

1. What are Nuc, Flag, ER, Mito, Chlora, Golgi, Ves and Lys short for ? What does each organeelles do in the cell ? Cholra stands for cholraplast which gathers energy from the sun light to create food for the cell, which is a process called photosynthesis. ER stands for Endoplasmic Reticulum the ER manufactures certain macromolecules, also it sorts and packages materials into transport vesicles. Flag stands for Flagellum, the Flag is a locomotion oraganelle composed of microtubes. Mito is short for Mitochondrion, this is where the celluar respiration takes place and most of the cells ATP. Nuc is short for Nuclus or Nucleous , the is used to produce ribosomes.Golgi stands for Golgi apparatus this organelle is in controlling the modification, sorting, and secreation of cell products. Lys is short for Lysosomes , this is the digestive organelle where the macromolecules are hydrolyzed. Ves is short for Vessicals.
2. What is and autogenic hypothesis of the origin of the eukaryotic cell? The autogenic hypothesis of the origin of the eukaryotic cell is that the eukaryotic presxsisted as a prokaryotic cell.
3. What is the evidence that supports the autogenic hypothesis? A process called membrane folding, which folded and created the eukaryotic cell , that explains why the different parts of the eurkayotic cell has

    The technological advancements, in the scientific field, have opened opportunities for scientists to accumulate knowledge and understanding of the cell theory and have thus provided justification to the living organisms that exist. Notably, prior to the proposal of the cell theory, limited knowledge and understanding of what humans comprised of was evident and thus the theory of spontaneous generation was brought forth. This theory, which has been disproved by Virchow in 1855, suggests that living matter arouses spontaneously from non-living matter. As a consequence of limited technology, many people believed this theory as technological inventions like the light compound microscope, which showed life, were non-existent at the time. Evidently, in 1665, Robert Hooke, an English scientist, invented his own compound microscope and observed the cellular nature of the cork. The topic of cells was brought forth and from this moment, in 1674 Leeuwenhoek viewed microscope ' animalcules' and in 1838, Schleiden and Schwann produced the cell theory, stating that all living things are made of cells and cells are the basic unit of organisms. Moreover, the technological introduction of stains were developed and assisted scientists to efficiently see cells and their internal structures. This staining technique, as a result of technology, created a contrast between the transparent material and its background, presenting a clear image of the cell. Therefore, through the technology advancement in staining techniques, the processes of the cells and nuclear division of the cell were visible. Significantly, towards the end of the 19th century, compound light microscopes had been developed to a point where the resolving power of microscopes was diminishing, with difficulty in separating objects. The next scientific breakthrough was evident as a result of the…

    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.…

    Psychologists from the biological approach assume that behaviour and experiences are caused by activity in the nervous system of the body. The things that people think and feel, say and do are caused, one way or another, by electrochemical events occurring within and between the neurones that make up their nervous system, particular those in the brain. Many biopsychologists also agree that because the development of the brain is determined (at least partly) by the genes a person inherits, that behaviour may be influenced by genetic factors. Furthermore, because the genes we inherit are the result of evolution, many biopsychologists think that behavioural and psychological characteristics may have evolutionary explanations.…

    All living organisms are composed of one or more cells, and like any living organism, cells are made up of smaller structures that help them function. In the context of cells, these smaller structures are referred to as organelles and each organelle has its own unique function that has developed over time. While we are typically aware of how these organelles function, how they evolved raises several questions. The main model for how eukaryotic cells evolved over time is the endosymbiont theory. This theory proposes that the organelles distinguishing eukaryote cells, evolved through symbiosis of single-celled prokaryotes.…

    The cell is the most basic unit of life. The cell serves as the place for processes such as cellular respiration, metabolism and energy production in the form of ATP, or adenosine triphosphate. Many organelles—small structures that help to carry out the daily operations of the cell, inhabit the cell such as the Golgi complex, the endoplasmic reticulum, the nucleus, or brain of the cell, and lysosomes. An organelle that is the place where most of the cell’s energy is generated is called the mitochondrion. The mitochondrion, commonly named “the powerhouse of the cell,” is found in most eukaryotic cells, and the number of mitochondria within a cell can vary; however, this depends on the organism and the tissue type. This organelle is so unique that it contains its own DNA. This is so because the mitochondrion is theorized to have once been a cell on its own according to the endosymbiotic theory which suggests that the mitochondrion has a distant bacterial history. While the main function of the mitochondrion is energy production, other functions are heat production, aid in cell death and storage of calcium ions.…
