Crawling Chemicals Act Like They Are Alive
The article, “Crawling Chemicals Act Like They Are Alive” by Kathryn Gempf, discussed a Japanese teams creation of ‘globules’, which are a combination of multiple chemicals and also known as vesicles, that acted as if they were alive by showing some of the human life characteristics. The team believes that these globules may contain clues to the origin of simple cells, however no new information about the origin of cells has been extracted from this study yet. The globules moved around freely, but required food to provide them their energy, otherwise they would collapse and shrink. Since they ate (mostly other chemicals or smaller globules), they also would excrete excess chemicals, which was another intriguing life-like characteristic. This

    1a – Explain the structures of a human cellMost human cells contain small structures known as organelles (“little organs”), each of which performs a highly specialised task, such as manufacturing protein. Organelles are usually surrounded by a membrane, and they float in a jelly-like substance called cytoplasm. Ninety percent of cytoplasm is water; it also contains enzymes, amino acids, and other molecules needed for cell functions. The structure…

    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…

    In 1663, Robert Hooke, proposed that organic matter was composed of what he called, cells. He was able to view these cells as he used a simple microscope, which allowed him to see what organisms were composed of. The advent of the simple microscope however was not enough for the scientific community to accept this theory, as the images had low resolution. So between 1674 – 1683, Anton Van Leewenhoek developed a microscope that allowed for greater magnification, of upto 200x. This increased magnification and resolution has allowed him to view bacteria, and this time the scientific community accepted the findings due to the resolution of the images. In 1838, German scientists, Theodor Schwann and Mattibias Schleiden, discussed the similarities in the animal and plant cells that they were observing through their compound light microscopes. They observed that both cells contained nuclei, and this provided them with the basis of their cell theory. The availability and magnification of microscopes made this discovery possible, and is what provided two of the 3 main points of the cell theory. The final part of the theory, that states that all cells come from pre existing cells, was proposed by Rudolf Virchow. Through his microscope, he was able to witness and name the process of mitosis, which is how cells reproduce.…

    Microbodies were first discovered and named in 1954 by Rhodin. De Duve chose the name of Peroxisome because of its relationship with hydrogen peroxide. In 1967, Breidenbach and Beevers were the first to isolate microbodies from plants, which they named Glyoxysomes because they were found to contain enzymes of the Glyoxylate cycle.…

    No general full fledged definition for life has been articulated since time, but lists of properties have been suggested to discern ‘the inert/non-living’ from ‘the living’ of which a an organism has to posses in order for it to be considered as a living being. These include self organization or movement, growth, reproduction, inheritance, feeding, excretion, sensitivity and adaptation. Moreover, the question of what life is takes us back to evolution, that is, for an organism to be considered living, it has to be part of the fossil record. Even so, there are living organisms which do not show some of these characteristics of life.…

    As we all probably know today, every single living being is made up by cells – the building blocks of life. As much as we would like to take this fact for granted, we cannot help but acknowledge and remember the works and discoveries of earlier scientists which all contributed to our today's understanding of the cell theory. The cell theory being; all living things are composed of one or more cells, cells are organisms' basic units of structure and function, and cells only come from existing cells. Their discoveries lead to the development of inventions necessary to induce further research in the area which resulted in the creation of devices such as the microscope.…

    Life is defined as a characteristic that distinguishes that have signaling and self sustaining processes from those that don’t. If an organism can perform certain functions such as movement, respiration, sensitivity, growth, reproduction, excretion, and nutrition, it is classified as a living organism. Life began from the basic building block of all living things, called cells. All organisms derived from single celled organisms. Cells are the basic building blocks of life and are found in all living things. For example, a group of cells would form a tissue, a group of tissues would form an organ, a group of organs would form an organ system an a group of organ systems would form an organism.…

    A-Level biology catalysed my interest in the subject. I was enthralled by a taster lecture at the University of Cambridge on the semi-independent life of mitochondria. The lecture explored mitochondria’s double-stranded DNA and its frequent mutations that increase exponentially with age. I was particularly intrigued by the mention of Lynn Margulis’ symbiogenesis theory. Upon further research, the idea that free-living bacteria were taken inside another cell over a billion years ago seemed plausible and yet fascinating.…
