Micro Chapter 12 Flashcards
Q: What are some basic characteristics of fungi, and how do they compare with bacteria?
A: Fungi are eukaryotic, have chitin cell walls, and reproduce through spores. They can reproduce sexually or asexually. Bacteria are prokaryotic, have peptidoglycan cell walls, and reproduce by binary fission.
Q: What are the vegetative fungal structures?
A: Hyphae (filamentous structures), mycelium (network of hyphae), and yeast cells (unicellular fungi).
Q: What are the three types of asexual spores in fungi?
A: Conidiospores, Arthroconidia, and Blastoconidia
Q: What is mycosis?
A: Mycosis is a fungal infection in animals, including humans.
Q: What is systemic mycosis?
A: Systemic mycosis is a fungal infection that affects the entire body or multiple systems.
Q: What is subcutaneous mycosis?
A: A fungal infection beneath the skin.
Q: What is cutaneous mycosis?
A: A fungal infection affecting the skin, hair, and nails.
Q: What is superficial mycosis?
A: A fungal infection affecting the outermost layers of skin or hair shafts.
Q: What is opportunistic mycosis?
A: A fungal infection that occurs when the immune system is compromised.
Q: What organism causes Histoplasmosis, and what are the symptoms?
A: Histoplasma capsulatum; symptoms include flu-like symptoms, respiratory issues, and fever.
Q: What organism causes Coccidioidomycosis, and what are the symptoms?
A: Coccidioides immitis; symptoms include cough, chest pain, fever, and fatigue.
Q: What are the defining characteristics of Brown Algae?
A: Brown algae (kelp) have cell walls made of cellulose and alginic acid, and they produce algin, a thickening agent.
Q: What are the basic characteristics and structural components of fungi?
A:
* Eukaryotic organisms
* Cell walls made of chitin
* Can be unicellular (yeasts) or multicellular (molds)
* Reproduce via spores (asexual or sexual)
* Heterotrophic: Absorb nutrients from the environment
Q: What are the basic characteristics and structural components of protists (algae and protozoa)?
A:
* Algae: Photosynthetic, aquatic, cell walls often contain cellulose, unicellular or multicellular (e.g., seaweeds).
* Protozoa: Unicellular, heterotrophic, lack cell walls, often motile (via cilia, flagella, or pseudopodia).
Q: What are the basic characteristics and structural components of Animalia (helminths and arthropods)?
A:
* Helminths: Parasitic worms (flatworms, roundworms); multicellular; complex reproductive systems.
* Arthropods: Insects, arachnids; often vectors for disease (e.g., mosquitoes, ticks).
