Euk
Sterols present (ergosterol)
Chitin is main part with glucans and mannans

Yeasts - unicellular

Molds - multicellular

Question 3

Mycelia

Answer 3

Hyphae of molds that clump together

Question 4

Yeast morphology

Answer 4

Rounded single cells that bud (blastoconidia)…may have a capsule

Question 5

Mold morphology

Answer 5

Conidia or spores attached to hyphae…grow as multicellular filamentous colonies

Question 6

Hyphae

Answer 6

Tube like structures that may have septa…basic strucutral element of molds
Can be septate or aseptate…grow up from spore

Question 7

Basic sturcture of yeasts

Answer 7

Bud via blastoconidia
Can get pseudohyphae
Some have polysach capsule

Answer 8

Sabourads

Answer 9

Grow as either based on environment
35-37 = yeast
25-30 = mold
