Explanation: The scientific name of the button mushroom, which is a widely consumed edible mushroom, is Agaricus compestris.
Correct answer: Agaricus compestris- A. Absorption
- B. Reproduction
- C. Nutrition
- D. Locomotion
- E. Respiration
Explanation: Sporangiophores are specialized structures found in certain fungi, particularly in the group known as Zygomycetes.
Correct answer: Reproduction46. Why do molds grow on refrigerated items like oranges and jelly, where bacteria typically cannot?
- A. They are well adapted to live on land
- B. Hyphae are modified
- C. They can tolerate temperature extremes (-5°C and up to 50°C)
- D. They have rhizoids
Explanation: Fungi like molds can grow at lower temperatures where bactaria usually cannot survive.
Correct answer: They can tolerate temperature extremes (-5°C and up to 50°C)47. Yeasts are:

- A. Have chlorophyll and are autotrophs
- B. Have chlorophyll and are heterotrophs
- C. Lack chlorophyll and are autotrophs
- D. Lack chlorophyll and are heterotrophs
Explanation: Fungi are heterotrophic organisms without chlorophyll.
Correct answer: Lack chlorophyll and are heterotrophs- A. Autotrophs
- B. Heterotrophs
- C. Saprotrophs
- D. Chemotrophs
Explanation: Fungi that obtain their food directly from dead organic matter are called Saprotrophs.
Correct answer: Saprotrophs- A. Autotrophs
- B. Saprotrophs
- C. Obligate Parasites
- D. Facultative Parasites
Explanation: Obligate parasites require a living host to survive and grow.
Correct answer: Obligate Parasites- A. Predators
- B. Obligate Parasites
- C. Opportunistic Parasites
- D. Facultative Parasites
Explanation: Facultative parasites can survive both with and without a host.
Correct answer: Facultative Parasites- A. Fungi and Nematodes
- B. Fungi and Green Algae

- E. Fungi and fungi
Explanation: Lichens involve fungi and green algae or cyanobacteria working together.
Correct answer: Fungi and Green Algae- A. Water
- B. Wind
- C. Food
- D. Man
Explanation: Fungi primarily rely on the wind to disperse their spores across large areas, allowing them to colonize new environments.
Correct answer: Wind- A. Zygospore
- B. Conidia
- C. Basidiospore
- D. Ascospore
Explanation: Zygospores are diploid and form after karyogamy in Zygomycota during sexual raproduction.
