EARLY PROKARYOTES 1: Microbial mats representing the earliest form of life on earth

    Microbial mats as the earliest form of life on earth


Microbial also represent the earliest form of life on earth in which there is a record of fossil evidence of their presence starting about 3.5 billion years ago. This early life organism ( microbial mats) is a multi-layered sheet of micro organism ( prokaryotes) which include mostly bacteria,but also Archaea. 
Microbial mats are said to survive, thrive or inhabitate in different environment either on moisture environment or submerged environment and few of them can successfully adapt and survive in deserts. Prokaryotes in a microbial mats are held together by a glue-like sticky substance that they secrets called Extracellular Matrix. 
According to research, the first microbial mats are likely to obtained their energy from chemicals found near an hydrothermal vents.A hydrothermal vent is a fissure on the seafloor from which geothermally heated water discharge.

Microbial mats depends on hydrothermal vents for energy and chemical food, but the development of photosynthesis allow mats to spread more abundantly or to increase in number to outside of these environment by making use of the available energy source.

Do you know?
  Microbial mats are to be credited to be one of the organism which produce the atmosphere we are today, in which free oxygen is a vital components. Microbial mats may also said to have been the birthplace of more complex eukaryotic type of cell and of which all multicellular organisms are composed of .

HISTORY TODAY: The three co - Founder Of Cell Theory

      Three Co - Founders Of Cell Theory This section of this article will be a discussion basically on the three Co- founders of the cell theory. Here this paper shall be discussing basically on who are those that postulated the cell theory ( modern cell theory). Matthias schleiden ( 1804 - 1881) was a German botanist and co - founder of cell theory, along with theodor schwann and Rudolf Von Virchow. the image above represent Rudolf Von Virchow Born in Hamburg, schleiden was educated at University of jena,, but he developed his love and passion for botany into a full - time pursuit. Schleiden liked or habit to study plants structure under the microscope. So he became a professor of botany at the University of jena, there he wrote contribution to our knowledge of phytogenesis ( 1838), in which he stated that all parts of plant organisms are composed of cells,as it was discussed before. However, schleiden and schwann became the first to formulate what was then ...

DEVELOPMENT OF MULTICELLULAR ORGANISM: Process of Development

                    Process Of Development    According to research and observations, scientist affirmed that there are four essential process by which a multicellular organisms is made, which are cell proliferation, cell specialization, cell interaction and cell movement. Cell proliferation       Cell proliferation refers to the process that result in an increase in the number of cells. It is a fundamental process among living organisms that is necessary for general development ( Embryonic development, organ growth and development as well as various physiological process).     This is the first process in the development of multicellular organisms which involves the growth and division of the cells. Here the cells divides through a process know mitosis ( Somatic cell division) producing two equal copies of themselves. During this process, growth factors signal pathways which ser...

NEW DISCOVERY : Muscle Cell Secret

-

                         MUSCLE CELL SECRET A muscle fiber consists of just one cell, but many nuclei. A team at the MDC led by Professor Carmen Birchmeier has now shown just how varied these nuclei are. The study, which has been published in  Nature Communications , can help us better understand muscle diseases such as Duchenne muscular dystrophy. Usually, each cell has exactly one nucleus. But the cells of our skeletal muscles are different: These long, fibrous cells have a comparatively large cytoplasm that contains hundreds of nuclei.  But up to now, we have known very little about the extent to which the nuclei of a single muscle fiber differ from each other in terms of their gene activity, and what effect this has on the function of the muscle. A team led by Professor Carmen Birchmeier, head of the research group on Developmental Biology / Signal Transduction at the Max Delbrueck Cen...
