introduction
1. Cytology and Cell Biology
Three cornerstones of modern biology
Cell theory, evolution, genetics
Four stages in the development history of cell biology
The discovery of cells, the establishment of cell theory and its significance, from the classical period of cytology to the period of experimental cytology, the formation and development of cell biology
discovery of cells
In 1665, Hooke discovered plant cells for the first time; in 1674, Leeuwenhoek discovered red blood cells.
The establishment and significance of cell theory
The establishment of cell theory
From 1838 to 1839, Schleiden (Germany) and Schwann (Germany) proposed the "cell theory"
①All living things are composed of cells
②Each cell is a relatively independent unit
③Existing cells reproduce to produce new cells
In 1858, German physician and pathologist Virchow discovered a cell derived from
The significance of cell theory
It has advanced human understanding of life and promoted the development of science. It is jointly known as the theory of evolution and genetics. The three cornerstones of biology
2. Identity and Diversity of Cells
1 Basic characteristics of cells
basic common features of cells
①Similar chemical composition
②The cytoplasm is a membrane lipid-protein system
③The genetic device is the same
④Split into two parts
Cells are the basic unit of life activities
①The basic unit that constitutes an organism
②Basic unit of metabolism and function
③Basics of organism growth and development
④The basic unit of reproduction and the bridge of inheritance
⑤The destination of the origin of life and the starting point of biological evolution
Cell size and its influencing factors
cell size
In higher animals and plants, the cell size of the same organ and tissue is within a constant range, regardless of species differences.
The amount of protein and ribosomal RNA in the fibrils determines the size of the fibrils
Influencing factors
mTOR, a protein kinase at the center of signaling pathways
The stage of the cell
nuclear DNA content
2 basic types of cells
(1) Prokaryotic cells
Features
represent
bacteria
cyanobacteria
(2) Eukaryotic cells
3 basic structural systems
biofilm structural system
Genetic information transmission and expression system
cytoskeletal system
How macromolecules are assembled
Self-assembly, assisted assembly and direct assembly
(3) Archaocyte
basic structure
3 Viruses and their relationship with cells
The difference between viruses and cells
structure
Features
Viruses multiply inside cells
Virus recognition and invasion of cells - viral nucleic acid replication, transcription and protein synthesis, virus assembly, maturation and release
