Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.

1561. Most fungi are
- A. Autotrophs
- B. Heterotrophs
- C. Photosynthetic
- D. All of the given options
Explanation: Fungi are heterotrophic organisms that absorb nutrients from decomposing matter or living hosts.
Correct answer: Heterotrophs- A. Swelling
- B. Minute branchin
- C. Both Swelling and Minute Branching
- D. None of the given options
Explanation: Endomycorrhizae cause both swelling and branching within the root cells, aiding in better nutrient absorption.izal colonization.
Correct answer: Both Swelling and Minute Branching- A. Fungi
- B. Algae
- C. Bacteria
- D. Viruses
Explanation: The fungal component of lichens provides structural support and prevents water loss.
Correct answer: Fungi- A. Glucose
- B. Glycogen
- C. Starch
- D. Protein
Explanation: In fungi, the food is stored in the form of oil droplets and glycogen. In plants, starch is the storage food.
Correct answer: Glycogen- A. Yeast
- B. Penicillium
- C. Aspergillus
- D. Neurospora
Explanation: In the food industry, certain fungi are used to give flavor, aroma, and color to specific foods especially cheese.The genus Penicillium is…
Correct answer: Penicillium- A. Shape
- B. Size
- C. Sexual reproduction
- D. Asexual reproduction
Explanation: The correct basis for dividing fungi into different divisions or phyla is "sexual reproduction." Fungi are classified primarily based on…
Correct answer: Sexual reproduction- A. Ascomycota
- B. Basidiomycota
- C. Ascansmycota
- D. Deuteromycota
Explanation: "Deuteromycota, also known as "fungi imperfecti" or "imperfect fungi," is a group that includes fungi that do not exhibit a known sexual…
Correct answer: Deuteromycota- A. Physiology
- B. Parasitology
- C. Mycology
- D. Ecology
Explanation: The correct answer is Mycology, which is the scientific study of fungi, encompassing their taxonomy, structure, properties, and uses.
Correct answer: Mycology- A. Decomposer
- B. Foodstuff
- C. Baking and brewing
- D. All of these
Explanation: The correct answer is Decomposer. Both fungi and bacteria play crucial roles as decomposers in ecosystems.
Correct answer: Decomposer- A. They resemble plants
- B. They resemble animals more than plants
- C. They are neither plants nor animals
- D. They are distinct from plants, animals, and protists
Explanation: The correct answer is that fungi are distinct from plants, animals, and protists.
Correct answer: They are distinct from plants, animals, and protists- A. Contain chitin in their cell wall
- B. Exhibit nuclear mitosis
- C. Forms mycorrhizae
- D. Absorptive heterotrophs
Explanation: This question tests fungal biology, essential for medical students in mycology.
Correct answer: Contain chitin in their cell wall- A. Have cell wall
- B. Nuclear mitosis
- C. Non motile
- D. Absence of centrioles
Explanation: The correct answer is Nuclear mitosis because this process is a defining feature of fungi that does not resemble the plant reproductive…
Correct answer: Nuclear mitosis- A. Nuclear mitosis
- B. Cellulose in their cell wall
- C. Non motile
- D. Absence of centriole
Explanation: This question tests fungal characteristics, critical for medical students in mycology.
Correct answer: Cellulose in their cell wall- A. Animals
- B. Algae
- C. Bryophytes
- D. Angiosperms
Explanation: This question tests evolutionary biology, relevant for medical students in mycology.
Correct answer: Animals- A. Cellulose
- B. Chitin
- C. Lignin
- D. Pectin
Explanation: This question tests biochemical composition, important for medical students in mycology and zoology.
Correct answer: Chitin- A. Trichome
- B. Filament
- C. Mycelium
- D. Mushroom
Explanation: The correct answer is Mycelium. Mycelium refers to the network of hyphae that forms the main vegetative growth of a fungus.
Correct answer: Mycelium- A. Monokaryotic
- B. Dikaryotic
- C. Coenocytic
- D. Akaryotic
Explanation: Coenocytic hyphae are a type of fungal hyphae that lack septa, resulting in a continuous cytoplasmic mass containing multiple nuclei.
Correct answer: Coenocytic- A. Fungi
- B. Algae
- C. Angiosperms
- D. Bryophytes
Explanation: The correct answer is Fungi. The largest known organism by area is a species of fungus called Armillaria ostoyae, also known as the honey…
Correct answer: Fungi- A. Coenocytic
- B. Hyphal
- C. Non-hyphal
- D. Septate
Explanation: This question tests fungal morphology, critical for medical students in mycology.
