The difference between erect hyphae and vegetative hyphae, the role of erect hyphae

<>1. Different morphologies: erect hyphae are straight or branched filaments, and the color is darker than vegetative hyphae, while vegetative hyphae are creeping and lighter in color. 2. Different functions:

Erect hyphae are usually used for reproduction, and sometimes spores are produced after a certain stage of development, and the vegetative hyphae can absorb nutrients and can also produce different pigments, which are generally used to identify the species. 3. The production mode is different: the erect hyphae are obtained from the basal vegetative hyphae after growing out of the medium, and the vegetative hyphae creep grow on the surface of the substrate or extend to the inside of the substrate.

1. The difference between erect hyphae and vegetative hyphae.

1. Different forms.

1) Erect hyphae: erect, branched filaments, thicker and darker in size and color than vegetative hyphae.

2) Vegetative mycelium: Creeping growth, lighter in color and shiny.

2. Different functions:

1) Erect hyphae: Generally used for propagation, some erect hyphae will differentiate into reproductive hyphae after developing to a certain stage, and will produce spores.

2) Vegetative hyphae: The main function is to absorb nutrients, and some vegetative hyphae will produce different pigments, which can be used to identify strains.

3. Different ways of generation.

1) Erect hyphae: actinomycete hyphae that grow from the basal vegetative hyphae outside the medium and extend into the space.

2) Vegetative hyphae: Creeping grow on the surface of the nutrient substrate, or extend into the interior of the substrate, similar to the root system of plants.

Second, the role of erect hyphae.

1. Erect hyphae can be used for reproduction, such hyphae will grow into the air, and some erect hyphae will produce spores after they develop to a certain stage.

2. The erect hyphae are superimposed on the vegetative hyphae, which allows it to cover the surface of the entire colony, and it is darker in color (some will also produce pigment) under the light microscope, and the diameter is also larger than the vegetative hyphae.

3. The top of the erect hyphae of Penicillium has a broom-like structure and a bunch of spores; Aspergillus has a radial structure at the tip of the erect hyphae and relies on spores for reproduction.

The main differences between erect hyphae, scientific name aerial hyphae, and vegetative hyphae are as follows:

First, the way of generation is different.

1. Aerial mycelium: actinomycete hyphae that extend to the space outside the medium from the basal vegetative hyphae.

2. Vegetative hyphae: Intrabasal mycelium creep on the surface of the nutrient substrate or extend to the inside of the substrate, and they are like plant roots.

Second, the functions are different.

1. Aerial hyphae: spore filaments used for reproduction.

2. Nutritional mycelium: the main function is to absorb nutrients, and some can produce different pigments, which is an important basis for the identification of strains.

Third, the form is different.

1. Aerial hyphae: Aerial hyphae are straight or branched filamentous, thicker and darker than the basal hyphae.

2. Vegetative hyphae: When observed under the microscope, the general aerial hyphae are darker in color and thicker than the hyphae in the base; The basal hyphae are light and shiny. Some actinomycetes have well-developed aerial hyphae, some are sparse, and some species have no aerial hyphae.

Mushrooms are erect hyphae.

and vegetative hyphae They tend to form branching and luxuriant mycelium.

Nutritional hyphae, also known as intrabasal hyphae, the main function is to absorb nutrients, some can produce different pigments, is an important basis for the identification of strains, aerial hyphae, superimposed on the vegetative hyphae, also known as secondary hyphae cell membrane, cytoplasm, nucleus The top of the erect hyphae will expand into a radial sporangia, which contains spores, and reproduces offspring with spores, and it becomes yellow when it matures

So the answer is: nutrients, spores.

The characteristics of the vegetative hyphae of actinomycete vibrator are ().

a.Generally, there is no diaphragm, and even if there is, it is very rare.

b.The diameter is microns, and the length varies greatly, 100-600 microns.

c.Some of the vegetative hyphae of actinomycetes form cavity pigments, and some do not.

d.Spore filaments can be specialized.

Correct answer: ABC

Nutritional hyphae, also known as intrabasal hyphae, the main function is to absorb nutrients, some can produce different pigments, is an important basis for the identification of strains, aerial hyphae, superimposed on the vegetative hyphae, also known as secondary hyphae cell membrane, cytoplasm, nucleus The top of the erect hyphae will expand into a radial sporangia, which contains spores, and reproduces offspring with spores, and it becomes yellow when it matures

So the answer is: nutrients, spores.
