Free Kingdom Fungi MCQs with Answers

91. 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.

92. Endomycorrhizae may enter the outer cells of the plant root and cause

• 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.

93. In lichens, protects its symbiotic partner from desiccation.

• A. Fungi
• B. Algae
• C. Bacteria
• D. Viruses

Explanation: The fungal component of lichens provides structural support and prevents water loss.

94. The stored food in fungi is usually lipid droplets of:

• 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. In animals, glycogen is the storage of food.

95. Fungi are used in food industry, which fungi is used in bakery for flavor, aroma, color to some cheese:

• 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 most commonly used in cheese production.

96. Fungi are divided into 4 division/phyla on the basis of:

• 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 the characteristics of their sexual reproductive structures, such as the formation of spores and the arrangement of sexual organs. These reproductive structures are essential for distinguishing different groups of fungi and understanding their evolutionary relationships

97. Fungi that have lost the ability to reproduce sexually are classified in group:

• 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 reproductive phase or have lost the ability to reproduce sexually. These fungi are characterized by their exclusive or predominant mode of asexual reproduction. They reproduce through processes such as fragmentation, budding, or the production of asexual spores called conidia."

98. Study of fungi is called:

• 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. The other options refer to different branches of biology: Physiology focuses on the functions of organisms, Parasitology on parasites and their interactions, and Ecology on organism-environment interactions. These fields may overlap with mycology, but they are not exclusively concerned with fungi.

99. Which of the following fungal role parallels to that of bacteria?

• 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. They break down dead organic material, returning essential nutrients to the soil and supporting nutrient cycles. This ecological function is vital for the sustainability of ecosystems. The other options do not parallel roles that fungi and bacteria share. While fungi are indeed used as food and in baking and brewing, these roles are not shared by bacteria in the same way.

100. Which statement explains taxonomic status of fungi?

• 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. The kingdom Fungi is characterized by its members having chitin in their cell walls, being heterotrophic (absorbing nutrition from other organic matter), and reproducing through spores. These features set them apart from plants (which have cellulose in their cell walls and are autotrophic) and animals (which ingest food). Furthermore, while protists can be similar in some ways, fungi's unique characteristics warrant a separate classification.Option A is incorrect because, although fungi were historically grouped with plants, they differ significantly in terms of cellular structure and nutritional methods. Option B is incorrect because, while fungi share some similarities with animals, such as being heterotrophic, they are distinct in other key ways. Option C is misleading because it doesn't fully express the distinct classification of fungi as their own kingdom.
