    Question: Module #6 Chapter 11 Books cited: Becker’s world of the cell: J. Hardin, G. Bertoni, and L. Kleinsmith: 8th edition; pgs.298-299 & 301-307. Question #2 from D2L: The endosymbiont theory attempts to explain the evolutionary origin of eukaryotes. Describe this theory in a paragraph. Be sure to use these terms: semiautonomous organelles, symbiotic relationship, protoeukaryote, purple bacteria, cyanobacteria, mitochondria, and chloroplasts. Through research it was discovered that…

    Observation of plant and animal cells through a light microscope. A cell is the most basic structure of any living organism and is capable of independently reproducing. Cells can be grouped into two categories, prokaryotic and eukaryotic. In a eukaryotic cell there are small organelles that carry out specific functions which can be compared to the organs in the human body. Some of these organelles include the nucleus, which holds the cells DNA, mitochondria, which produce ATP from glucose and…

    The smallest unit within a living thing is known as a cell. Organisms are also a living thing and cell is considered to be the basic block of organisms that builds them. There are many different types of cells in a living thing and are divided into two main categories (i) prokaryotic and eukaryotic. (Karp, 2010). Characteristics of living cell Cells are considered as the most fundamental unit that has the responsibility to carry functions within a living organism (De Robertis & De Robertis,…

    There are many things that are common between plant and animal cells, I'll name five. First off, both cells contain nuclei and both make up eukaryotes. Both types of cells have a cytoplasm which contains various organelles. Both plant and animal cells have a cell membrane that surrounds. The different types of cells contain many of the same organelles such as ribosomes, smooth endoplasmic reticulum…

    have no membrane bound organelles. Prokaryotes can be divided into two domains, Archaea and Bacteria. However organisms, whose cells are organized into complex structures by a nucleus, contain internal membranes and a cytoskeleton are known to be Eukaryotes. Similarly plant and animal cells can be classified into eukaryotic cells. Both organisms contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and peroxisomes. Furthermore…

    Forensic science, known as forensics, is the application of science to law by analyzing DNA for legal evidence. DNA profiling is the predominant application and forensic science, DNA profiling allows us to take more than one sample of an unknown DNA specimen and determine if it has the same genetic match. Moreover, DNA profiling is to help determine and solve crime scenes such as murders, assaults, and rapes. The technique used for analyzing DNA is restriction fragment length polymorphism…

    MITOCHONDRIAL SRUCTURE Mitochondria can be seen in the light microscope, but their detailed internal structure is only revealed by electron microscopy. As ubiquitous, semi-autonomous cellular organelles, mitochondria are separated from the cytoplasm by the outer and inner mitochondrial membrane.The outer membrane is porous and freely traversed by ions and small, uncharged molecules through pore-forming membrane proteins (porins), such as the voltage-dependent anion channel VDAC [19]. Any larger…

    In the prokaryote cell, all the components of the cell are in the cytoplasm because they do not have a cell nucleus but in the eukaryote cell, the materials in the cell nucleus are separated from the cytoplasm. It is dominated mainly of water, but there are some enzymes like protein salts, organelles (mitochondria, Golgi apparatus and so on) and various organic molecules. The cytoplasm…

    and cellular biology. While cells are the building blocks of all living organism, scientists have confirmed that there are actually different types of cells depending on the organism. The two main classes of organisms are the prokaryotes and the eukaryotes. The prokaryotic is the simpler of the two and are the one-celled organisms such as bacteria and archaea. The interior of a prokaryotic cell consists of a main nucleoid, which contains the DNA, the ribosomes, which synthesize proteins, and the…

    structure, absorb nutrients from food and convert those nutrients into energy so that the cell can carry out specialized functions. There are two main categories with most organisms and their cells; prokaryotes and eukaryotes. The distinctive difference between prokaryotes and eukaryotes is that eukaryotic cells contain membrane-bound organelles, such as the nucleus, while as prokaryotic cells do not. Plant cells are eukaryotic, plant cells have a nuclei and membrane bound organelles. The main…
