    which he called ‘cells’ this in itself unbeknownst to him‚ was the discovery of the fundamental unit of all living things. In 1838 a botanist called Schleiden derived the theory ‘The basic unit of structure and function of all living organisms is the cell.’ Over 150 years later this can be regarded as one of the most familiar and important facts within the biological fields. Drawing of cork cells published by Robert Hooke 1665 The Cell itself and use

    • 5 Pages

    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). Ultrastructural research and modern molecular biology have

    Cell Organelles Nucleus Its function is to control the cell’s activities and retain the chromosomes.  The nucleus is bound by a double membrane‚ the nuclear envelope. The nuclear envelope has pores in it to allow the transport of mRNA.  The cytoplasm like material is called nucleoplasm which contains chromatin (coils of DNA and histone proteins)‚ it is chromatin that condenses to form chromosomes during cell division.  Within the nucleus is a small spherical body called the nucleolus which

    Plant Cell Plant cells have many different parts that are need to work together and function as a whole. These parts are the cell membrane which can be compared to a "Condom" due to the fact that is a very thin protective layer that lets certain substances to pass through. Cell wall is a thicker rougher membrane‚ which gives the plant most of its structure and support‚ the cell wall also bond with other cell walls to form the structure of the plant. Centrosome may be also referred to as the

    The prokaryotic cell precedes any forms of Bacteria‚ Archaea‚ and eventually Eukaryotes by approximately two billion years. This cell was the original life form on the planet and represents the smallest and least complex of all organisms. Through the process of mutation and adaptation they were able to survive to evolve into our modern day Bacteria‚ Archaea‚ Fungi and Protists. These post organisms have benefited from their early ancestor‚ by way of Endosymbiosis. Intricate protest and fungi are
