  2. Symbiotic bacteria - Wikipedia

    en.wikipedia.org/wiki/Symbiotic_bacteria

    Symbiotic bacteria are able to live in or on plant or animal tissue. In digestive systems, symbiotic bacteria help break down foods that contain fiber. They also help produce vitamins. Symbiotic bacteria can live near hydrothermal vents. They usually have a mutual relationship with other bacteria. Some live in tube worms.

  3. Endosymbiont - Wikipedia

    en.wikipedia.org/wiki/Endosymbiont

    The Rhizobia-Legume symbiosis (bacteria-plant endosymbiosis) is a prime example of this modality. [21] The Rhizobia-legume symbiotic relationship is important for processes such as the formation of root nodules. It starts with flavonoids released by the legume host, which causes the rhizobia species (endosymbiont) to activate its Nod genes. [21]

  4. Microbial ecology - Wikipedia

    en.wikipedia.org/wiki/Microbial_ecology

    Microbes, especially bacteria, often engage in symbiotic relationships (either positive or negative) with other microorganisms or larger organisms. [44] Plants and animals happen to be the habitat of microorganism that are involved in mutualistic relationship. [45]

  5. Vertical transmission - Wikipedia

    en.wikipedia.org/wiki/Vertical_transmission

    The head louse (Pediculus humanus) has an obligate symbiotic relationship with Candidatus Riesia pediculicola. The louse provides shelter and protection while bacteria provides essential B vitamins. C. riesia lives in the bacteriocyte but move to the ovaries to be transmitted to the next generation. [26] [27]

  6. Endophyte - Wikipedia

    en.wikipedia.org/wiki/Endophyte

    There was a belief that plants were healthy under sterile conditions and it was not until 1887 that Victor Galippe discovered bacteria normally occurring inside plant tissues. [2] Though, most of the endophytic studies reports the mutualistic relationship of bacteria and fungus, Das et al., (2019) reported about endophytic virome and their ...

  7. Symbiosis - Wikipedia

    en.wikipedia.org/wiki/Symbiosis

    Symbiosis is also classified by physical attachment. Symbionts forming a single body live in conjunctive symbiosis, while all other arrangements are called disjunctive symbiosis. [ 4 ] When one organism lives on the surface of another, such as head lice on humans, it is called ectosymbiosis ; when one partner lives inside the tissues of another ...

  8. Microbial symbiosis and immunity - Wikipedia

    en.wikipedia.org/wiki/Microbial_symbiosis_and...

    Humans are home to 10 13 to 10 14 bacteria, roughly equivalent to the number of human cells, [2] and while these bacteria can be pathogenic to their host most of them are mutually beneficial to both the host and bacteria. The human immune system consists of two main types of immunity: innate and adaptive.

  9. Heterotrophic nutrition - Wikipedia

    en.wikipedia.org/wiki/Heterotrophic_nutrition

    In contrast, green plants, red algae, brown algae, and cyanobacteria are all autotrophs, which use photosynthesis to produce their own food from sunlight. Some fungi may be saprotrophic, meaning they will extracellularly secrete enzymes onto their food to be broken down into smaller, soluble molecules which can diffuse back into the fungus.
