The expansion of microscopy in biology
In recent years, the application of electron microscopy in biology has been significantly expanded and developed rapidly. At present, it has achieved remarkable results in scientific research in plant protection, breeding of fine seeds, animal and plant variety identification, trait identification, composition analysis, soil improvement, pulp modification, wood processing, environmental protection and other aspects. Therefore, electron microscopy has penetrated into all aspects of human biology. The following is a simple example.
botany
(1) Use electron microscopy to observe the ultrastructure of plant tissues, explore their growth and development mechanisms, reveal the relationship between plant structure and function, and provide a theoretical basis for improving plant functions and increasing plant yields.
(2) Observe the variation of plant organs during the growth process to provide basis for improving cultivation techniques.
(3) Observe the structural characteristics of plants such as pollen, pericarp, seed coat, and leaf epidermis to provide scientific basis for pollenology and plant taxonomy.
entomology
By observing the organs and tissues of insects, we can deepen our understanding of their role in physiological functions, provide a basis for exploring various life phenomena and life patterns, and provide a theoretical basis for the prevention, control and elimination of insect pests.
(2) Use SEM electron microscopy to observe the microscopic characteristics of insects, which provides important basis for insect taxonomy, insect biology, and prediction and prediction of insect pests.
microbiology
(1) Observe and study the ultrastructural morphology of mycoplasma and other microorganisms, study the structure and growth and development of viruses, and also provide scientific research methods for the discovery and identification of new viruses and viroids.
(2) Study the structural morphology of actinomycetes, actinomycetes, etc. It is of great significance to classify it, identify the family and genus, and determine the source of the disease. In particular, further results can be obtained on the activities of pathogens, spores germination, and the way they invade the host.
pathology
Olympus microscopes study ultrastructural lesions in cells, tissues and organs of animals, plants and insects to provide scientific basis for prevention and treatment. Electron microscopy radiation whitening technology and **electron microscopy technology are widely used.
wood science
(1) Applying SEM to study the ultrastructure of wood can provide a basis for tree species identification, wood classification, etc. It also provides a basis for studying wood structure, forest growth environment and their utilization value.
(2) Applying SEM to study the modification, weathering, and decay characteristics of wood can provide new basis for the processing and comprehensive utilization of wood.
(3) Apply TEM to further classify wood, providing a theoretical basis for improving processing technology and changing the growth environment.
