sợi bên
Definition
- Noun:
- Paraphysis (in botany, specifically mycology): A sterile, thread-like filament found among the reproductive structures (such as asci) in the fruiting bodies of certain fungi, particularly in the hymenium layer of ascomycetes and some other fungi. Its primary function is often protective or supportive.
Usage Examples
- Noun:
- Kính hiển vi cho thấy các sợi bên nằm giữa các túi bào tử. (The microscope revealed the paraphyses situated among the asci.)
- Sự hiện diện của sợi bên là một đặc điểm nhận dạng quan trọng. (The presence of paraphyses is an important identifying characteristic.)
Advanced Usage
- In detailed taxonomic descriptions, the morphology of the paraphysis (e.g., whether they are branched, swollen at the tip, or contain pigments) can be a key diagnostic feature for classifying fungi.
Variants and Related Words
- Sợi (n): A general term for filament, fiber, or thread. In a biological context, it can refer to any thread-like structure.
- Sợi nấm (n): Hypha; the filamentous cell that is the basic building block of a fungus.
- Túi bào tử (n): Ascus; the spore-producing cell in ascomycete fungi, often found alongside paraphyses.
Synonyms
- Sterile filament: A descriptive synonym emphasizing its non-reproductive function.
- Hymenium filament: A contextual synonym indicating its location within the spore-bearing layer.
Related Terms
- Hymenium (n): The tissue layer in a fungal fruiting body containing the spore-producing cells (like asci or basidia) and associated sterile structures like paraphyses.
- Ascomycete (n): A major division (phylum) of fungi that produce spores in a sac-like cell called an ascus. Paraphyses are common in many ascomycetes.
