18
Q

Produce motile spores.

Q

Help plants grow larger and healthier when their hyphae grow within the plant’s roots?

A

Mycorrhizae

21
Q

Fungus and algae or autotrophic bacteria?

A

Lichens

22
Q

Is chronic superficial fungal
infection which leads to hypo pigmented or hyper pigmented patches on the skin?

A

Pityriasis versicolor

23
Q

Pityriasis versicolor (also called _________) is chronic superficial fungal
infection which leads to hypo pigmented or hyper pigmented patches on the skin.

A

Tinea versicolor

24
Q

Are a category of cutaneous fungal infections caused by more than 30
species of fungi?

A

Dermatophytoses

25
Q

These dermatophytosis fungi secrete an enzyme called _____, which digests keratin.

A

Keratinase

26
Q

Following invasion of the horny layer of the skin, the fungi
spread, forming a ring shape with a red, raised border. This expanding raised red border
represents areas of active inflammation with a healing center. This is appropriately called
ringworm, since it looks like a ring-shaped worm under the skin.

A

Tinea corporis

27
Q

This infection commonly begins between the toes, and
causes cracking and peeling of the skin. Infections required warmth and moisture, so it only
occurs in those wearing shoes.

A

Tinea pedis

28
Q

This condition primarily occurs in children. The infecting
organisms grow in the hair and scalp, resulting in red scaly lesions with loss of hair. The infection
appears as an expanding ring.

A

Tinea capitis

29
Q

Fungi infection where the nails are thickened, discolored, and brittle?

A

Tinea unguium

30
Q

Candidiasis is caused by _____?

A

Candida albicans

31
Q

Can infect the mouth (oral thrush), groin (diaper rash), and the vagina?

A

Candida

32
Q

Sac Fungi?

A

Phylum Ascomycota

33
Q

Club fungi?

A

Phylum Basidiomycota

34
Q

Zygote Fungi?

A

Phylum Zygomycota

35
Q

Imperfect Fungi?

A

Deuteromycetes

36
Q
