The Men Who Made Up The History Of Cells

A German botanist, Schleiden, Matthias Jakob (1804-81), worked with German physiologist Theodor Schwann to develop cellular physiology. Schleiden was born in Hamburg, received legal education at Heidelberg, left a law to learn botany, then taught at Jena University from 1839 to 1862. He was a controversial controversy at the time despising a botanist, they were limited to plant naming and explanation. Schlieden studied the plant under the microscope and thought that the plant consisted of recognizable units or cells. He said in 1837 that plant growth is produced by the production of new cells and speculated that new cells will be produced from the nuclei of old cells. Later discoveries prove that his role in the nucleus in mitosis or cell division is wrong, but his notion of using cells as a common structural unit of the plant, as they occur science into the life process At the cellular level which has the great influence of transferring attention - a revolution triggering the field of embryology. After Schlieden published a cell theory on plants one year later, his friend Shi Wan extended it to animals and combined botany and zoology under a unified theory.

What is a cell? Frogs, humans, elephants and other cells are the smallest constituent of living creatures. The human body itself consists of 37.2 trillion cells. This number is unspecified since the body produces and peels cells every day. These cells form the components of the human body. Certain cells usually aggregate together to form a specific tissue. These tissues then combine to form organs. The above organ can be combined with other organs to form a system

Cells are the basic structural and functional units of life. The body is composed of billions of cells. The cells are homemade, ie, new cells are prepared from existing cells by cell division. Through cell division, cells increase and the body grows. Cells are the source of life attributes such as reproductive, metabolic and energy use. Cells can be divided into two, prokaryotic and prokaryotic. Prokaryotic cells do not have prominent nuclear and chromosomal proteins (Russell, Hertz, & McMillan, 2016). Because there is no nuclear membrane, the nucleus is not protruding. An example is a bacterial cell. On the other hand, eukaryotic cells contain nuclear membranes with prominent nuclei along with many other organelles. One example is a human cell.

Eukaryotic cells consist of the following organelles, nucleus, chromosome, cytoplasmic organelle, and cell membrane. The nucleus is the main control center of cells in which DNA exists. Chromosomes are contained in the chromosome. DNA replication and transcription occurs in the nucleus (Russell, Hertz, & McMillan, 2016). DNA is transcribed into mRNA, which is translated into body protein within the ribosome. Ribosomes are organelles that play a role in protein assembly. A cytoplasmic organelle is an intercellular separation structure that performs a specific function. They include the Golgi apparatus, lysosomes, endoplasmic reticulum and mitochondria. The Golgi body consists of folded capsules, which are responsible for the packaging of pericellular material. Lysosomes are responsible for destroying all worn organelles in the body. The cell membrane is a semipermeable membrane surrounding the whole cell.
