What Is a Cytologist?

Cytology Cell is the basic unit of animal and plant structure and life activity. It was first proposed by German botanist Matthias Jakob Schleiden and zoologist Theodor Schwann from 1838 to 1839. Until 1858, Germany Weirshaw's idea that cells divide into new cells is more complete. It is a doctrine about the composition of biological organisms. The cytology demonstrates the structural unity and evolutionary common origins of the entire biological world. The cytology reveals the unity of cells. The establishment of this theory promoted the development of biology and provided an important natural scientific basis for dialectical materialism. The revolutionary mentor Engels once praised cell theory and the law of conservation and conversion of energy, Darwin's theory of natural selection, etc. as one of the most significant natural science discoveries of the 19th century. Cells are divided into prokaryotic cells and eukaryotic cells.

Before the nineteenth century, the work of many scholars focused on the microstructure of cells and engaged in morphological descriptions. The significance of the appearance of cells in various organisms has not been theoretically summarized until the Germans in the 1830s. According to Matthias Jakob Schleiden and Theodor Schwann: All plants and animals are composed of cells, and cells are the basic unit of all plants and animals. This theory is called "Cell Theory". In the 19th century, the work of many scientists has made great contributions to the creation of the Cell Theory, such as:

1. Jean-Baptiste de Lamark (1744 ~ 1829),

Controversy between cytology and new cytology. In the 1940s, Soviet female scholar Lebesinskaya announced her creation of the "New Cell Doctrine", which denounced German pathology

Revealed the unity of the cell and the unity of the structure of the organism.

revealed that there is a certain genetic relationship between living things.

(3) It indicates that biological research has entered the cellular level, which has greatly promoted the biological research process and laid the foundation for Darwin's theory of evolution.

Cytology is about cells as the basic unit of animal and plant structure and life activity

Hook in his book "Micrographs"

The cellular theory demonstrated the structural unity and evolutionary homology of the entire organism. The establishment of this theory has strongly promoted the development of biology
