Have chitin cell wall and are obligate aerobes
2
These are small, creamy, bacterial-like colony without aerial hyphae
Yeasts
3
Which is the correct order of budding process?
Lysis of cell wall, nucleus of the parent cell undergoes mitosis, a septum forms and the daughter cell breaks free, during fission, two cells of equal size are formed, lastly, cells continue to grow from the tips of the cell.
4
What is the difference of hyphae and mycelia?
Hyphae are single strands whereas mycelia are many strands
