Accepted Answer

Ascomycota

Question 3

Which of the following is a correct sequence of events in the sexual reproduction of fungi?

Accepted Answer

Plasmogamy → Karyogamy → Meiosis

Question 4

A patient presents with a chronic fungal infection deep within the body, acquired by inhaling spores from soil. Which type of mycosis is this?

Accepted Answer

Systemic mycosis

Question 5

Which structure in multicellular algae is responsible for anchoring the organism to a substrate?

Accepted Answer

Holdfast

Question 6

Which of the following best describes the nutritional type of most fungi?

Accepted Answer

Chemoheterotroph

Question 7

A fungus produces thick-walled spores by rounding and enlargement within a hyphal segment. What is this spore type called?

Accepted Answer

Chlamydospore

Question 8

Which of the following divisions of fungi is characterized by coenocytic hyphae and the production of zygospores during sexual reproduction?

Accepted Answer

Zygomycota

Question 9

Which type of asexual spore is produced in a chain at the end of a conidiophore and is not enclosed in a sac?

Accepted Answer

Conidiospore

Question 10

A patient with AIDS develops pneumonia caused by Pneumocystis. This is an example of which type of mycosis?

Accepted Answer

Opportunistic mycosis

Question 11

Which of the following is NOT a characteristic feature of algae?

Accepted Answer

They all form embryos during reproduction.

Question 12

Which of the following is a correct pairing of algal phylum and its pigment color?

Accepted Answer

Chlorophyta – Green

Question 13

Which of the following best describes the function of a vegetative hypha in fungi?

Accepted Answer

It obtains nutrients for the fungus.

Question 14

Which of the following is true regarding the clinical identification of fungi?

Accepted Answer

It relies on the microscopic examination of asexual spores.

Question 15

Which of the following is a distinguishing feature of Basidiomycota?

Accepted Answer

They reproduce sexually by forming basidiospores externally on a pedestal.

Question 16

Which of the following best explains why fungal infections are generally difficult to treat in humans?

Accepted Answer

Fungal cells are similar to animal cells, making selective toxicity challenging.

Question 17

Which of the following is a correct description of a coenocytic hypha?

Accepted Answer

It appears continuous with many nuclei and lacks septa.

Question 18

A scientist isolates a fungus that only forms asexual spores and has septate hyphae. To which group does it most likely belong?

Accepted Answer

Anamorphs (Deuteromycota)

Question 19

Which of the following is the correct formula for the process of meiosis in the fungal sexual life cycle?

Accepted Answer

Question 20

Which of the following best describes the role of a pneumatocyst in brown algae?
