A biological experimental microscope is a scientific instrument used to magnify small objects and enable them to be observed. Through the microscope, we can see many small structures and organisms that cannot be observed by the naked eye. When observing organisms, a microscope is a very important tool that can help scientists study the microstructure, cell tissue, and microbial species of organisms.

There are many types of organisms that are easy to observe under experimental biological microscopes, including bacteria, yeast, protozoa, cells, etc. Bacteria are a type of tiny single celled organisms that are widely present in nature. The morphology, structure, and growth of bacteria can be clearly observed through a microscope. Yeasts are a type of fungus that typically grow in sugary environments, and their cell structure and division can be observed under a microscope. Protozoa are a type of single-celled microorganisms widely distributed in water, and their movement, feeding, and other behaviors can be observed through a microscope.

In addition, a microscope can also be used to observe the cellular structure of plants and animals. Plant cells and animal cells are the fundamental units that make up plant and animal tissues. The cell membrane, nucleus, plastid, and other structures of cells can be clearly observed through a microscope. By observing the morphology and structure of cells, we can gain a deeper understanding of the growth and development processes of plants and animals, as well as the functions of living organisms.

Overall, the microscope is a very important scientific instrument that plays a crucial role in biological research. Through a microscope, we can observe many tiny organisms and microstructures, helping us gain a deeper understanding of their composition and function. Therefore, the microscope is one of the indispensable tools in biological research.
