Extended Applications of Microscopes in Biological Research
1. Botany
(1) Electron microscopes are used to observe the ultrastructure of plant tissues, explore their growth and development mechanisms, and reveal the relationship between plant structure and function. This provides a theoretical basis for improving plant performance and increasing crop yield.
(2) Observe variations of plant organs during growth to support the development of advanced cultivation techniques.
(3) Examine structural features such as pollen, pericarp, seed coat and leaf epidermis, providing scientific evidence for palynology and plant taxonomy.
2. Entomology
By observing insect organs and tissues, researchers gain deeper insights into their physiological functions. It provides a foundation for exploring life phenomena and biological rules, as well as theoretical support for pest control.
(2) Scanning electron microscopy (SEM) is used to observe microscopic features of insects, offering critical data for insect taxonomy, entomological research, and pest forecasting.
3. Microbiology
(1) Observe and study the ultrastructure of microorganisms such as mycoplasma, investigate viral structure and development, and provide research methods for the discovery and identification of new viruses and viroids.
(2) Study the morphology of fungi, actinomycetes and bacteria. It is vital for classification, genus identification and pathogen judgment. In particular, it helps researchers observe pathogen activity, spore germination and host invasion.
4. Pathology
Microscopes are used to study ultrastructural lesions in cells, tissues and organs of animals, plants and insects, supplying scientific evidence for disease prevention and treatment. Electron microscopic autoradiography and transmission electron microscopy are widely applied.
5. Wood Science
(1) Scanning electron microscopy (SEM) is applied to investigate wood ultrastructure. It supports tree species identification and wood classification, and helps study the correlation between wood structure, forest growth environment and utilization value.
(2) SEM is used to research wood modification, weathering and decay characteristics, providing new references for wood processing and comprehensive utilization.
(3) Transmission electron microscopy (TEM) enables further classification of wood and delivers theoretical support for optimizing processing technologies and adjusting growth conditions.
6. Pulp and Papermaking
(1) SEM is adopted to study ultrastructural changes of papermaking raw materials. TEM is used to analyze the particle size and dispersion of pulp fillers. The results offer theoretical guidance for developing optimal pulping processes and reasonable technical parameters.
(2) X-ray microanalysis is used to examine papermaking adhesives, fillers, pigments and paper sheets. It provides a basis for proper raw material selection and process design.
