Immunoglobulin (Microscopic 3D Schematic)
Antibody (Ab), also known as immunoglobulin (Ig), is a large Y-shaped protein mainly secreted by plasma cells and used by the immune system to identify and neutralize foreign substances such as bacteria, viruses, and other pathogens. It is only found in the extracellular fluid of vertebrates, such as plasma, and on the cell membrane surface of B cells. An antibody can uniquely recognize a specific foreign target through its variable region, which is called an antigen.
Staphylococcus aureus (microscopic 3D schematic)
Staphylococcus aureus (S. aureus), also known as "Staphylococcus aureus", belongs to the genus Staphylococcus and is a representative of Gram positive bacteria. It is a common foodborne pathogenic microorganism. The most suitable growth temperature for this bacterium is 37 ℃, pH 7.4, high salt tolerance, and can grow in an environment with a salt concentration close to 10%. Staphylococcus aureus often parasitizes the skin, nasal cavity, throat, gastrointestinal tract, abscess, and purulent sores of humans and animals, and is also ubiquitous in environments such as air and sewage.
Chlamydomonas reinhardtii (microscopic 3D profile)
Chlamydomonas, also known as "unicellular algae". Chlorophyta, Chlamydomonas family. The algal body is a single cell, spherical or oval in shape, with two equally long flagella at the front end, and can swim. There are two flexible vesicles at the base of the flagella; There is also a red eye spot near the front end of the cell. Large cup-shaped color carrier with one starch core. Asexual reproduction produces 2, 4, 8, or 16 motile spores; Sexual reproduction includes homogamy, heterogamy, and ovogenesis. Under unfavorable living conditions, cells stop swimming and undergo multiple divisions, forming a temporary population called an "indeterminate population" with a thick glial sheath on the periphery.
Archaea Profile (Microscopic 3D Model)
As a group, archaea are diverse in physiology and morphology. They can be aerobic, facultative anaerobic, or strictly anaerobic. Nutritionally, they range from chemoautotrophic inorganic organisms to organic trophic organisms. Some are mesophilic organisms; Others are hyperthermophiles that can grow above 100 ℃. Archaea are also diverse in morphology, and some archaea can proliferate through mechanisms such as binary division, budding, or others. Some of them are single cells, but they can also form mycelia or aggregates.
