1. Cell morphological structure: bacteria are unicellular microorganisms with different shapes, some are spherical and some are rod-shaped; Its cell structure is relatively simple, only simple cell walls, cell membranes, plasmids, ribosomes and so on. On the other hand, fungi are organisms composed of multicellular tissues. Common fungi are composed of interwoven filaments, and cells contain eukaryotic organs, such as nucleus, mitochondria and Golgi apparatus.
2. Nutrition mode: Bacteria are mostly chemically necessary bacteria, and they get nutrition by decomposing various organic and inorganic substances. For example, anaerobic bacteria can use high-energy chemical bonds and can be oxidized to lower chemical energy without oxygen molecules; The fungus is heterotrophs. Its nutrition way is by absorbing organic substances or organs, and it can also carry out photosynthesis.
3. Metabolites: There are significant metabolic differences between bacteria and fungi in carbon dioxide cycle and photosynthesis. Fungi can produce many enzymes to decompose matrix sources to produce ATP, instead of increasing rapidly through intracellular energy sources; On the other hand, bacteria are traditionally regarded as nutrients that can be utilized from various sources and can produce a large number of various metabolites.
4. Living environment: The living environment of bacteria and fungi is different. Bacteria have strong adaptability to the environment, and some bacteria can survive in various extreme environments, such as high temperature, low temperature, strong acid or strong alkali. Fungi are selective to the living environment, and usually like to grow and reproduce in humid or organic-rich environments.
The above is the basic difference between bacteria and fungi, I hope it will help you.
