What two categories of fungi cause human diseases?
A. primary and secondary
Primary and secondary: Primary and secondary are general terms for stages or classifications but are not the accepted categories used to describe fungi that cause human disease.
B. primary and vegetative
Primary and vegetative: Vegetative refers to the active, growing form of a fungus (hyphae or yeast), which is a morphological description, not a category of pathogenicity.
C. opportunistic and primary
Opportunistic and primary: Primary fungi can cause disease in healthy hosts, while opportunistic fungi cause disease mainly in immunocompromised individuals. These two categories encompass the major ways fungi lead to human illness.
D. secondary and opportunistic
Secondary and opportunistic: Opportunistic fungi are correct, but secondary is not used as a distinct category for fungal pathogens.
E. vegetative and reproductive
Vegetative and reproductive describe fungal growth forms or structures, not their disease-causing categories in humans.

Similar Questions
Cell walls are not typically found in
A. protozoa.
Protozoa: Protozoa are single-celled eukaryotic organisms that lack a rigid cell wall, allowing them greater flexibility and movement. Instead, they have a cell membrane that provides structural support.
B. algae.
Algae: Algae are photosynthetic organisms that typically have cell walls made of cellulose or other polysaccharides, which provide structure and protection.
C. fungi.
Fungi: Fungi possess cell walls composed mainly of chitin, which gives them rigidity and structural strength, important for their survival.
D. bacteria.
Bacteria: Most bacteria have cell walls, usually made of peptidoglycan, which helps maintain their shape and protects them from osmotic pressure.

In humans, fungi can only infect the skin.
A. True
B. False
Full Explanation
False: While many fungal infections in humans are superficial, such as athlete’s foot and ringworm that affect the skin, fungi are not limited to infecting only the skin. Fungi can cause a wide range of infections, from superficial skin infections to systemic diseases affecting the lungs, bloodstream, and internal organs, especially in immunocompromised individuals.
Which type of microbial cell divides by budding?
A. Bacteria
Bacteria: Most bacteria reproduce by binary fission, where the cell divides evenly into two identical daughter cells. Budding is not a typical method of bacterial reproduction.
B. Algae
Algae: Algae generally reproduce through binary fission, fragmentation, or sexual reproduction, but budding is not their main reproductive mechanism.
C. Yeast
Yeast: Yeast, a type of fungus, often reproduce by budding, where a small outgrowth develops on the parent cell, enlarges, and eventually separates as a new individual cell.
D. Protozoa
Protozoa: Protozoa usually reproduce by binary fission or multiple fission, with some species reproducing sexually, but they do not reproduce by budding.
