What is the most common form of asexual reproduction among prokaryotes?
Binary fission
What is the name the original cell in binary fission, and what is the name of the resulting cells?
1 parent cell, 2 daughter cells
Which type of asexual reproduction among prokaryotes results in two final cells that do not fully separate but partially remain attached by a hinge like structure?
Snapping division
What is the final product of budding?

Waxy, mycolic acid in cell wall
What is the type of bacteria that has no cell wall?
Mycoplasma
What type of bacteria has a fried egg appearance when grown on media?
Mycoplasma (bacteria with no cell wall)
Where do bacteria without cell walls tend to colonize?
In osmotically protected habitats like animals and human bodies

No
What type of environment is required for protozoa?
Moist environments
Are the majority of protozoa pathogens?
No
What is a trait that well characterizes protozoa?
Great morphological diversity
How do protozoa reproduce?
Asexually only
All protozoa produce what structures?
Trophozoites
What is the purpose of contractile vacuoles?
They actively pump water from the cells to protect them from osmotic lysis
What is the motile feeding stage of a protozoa?
Trophozoites
What is the hardy resting stage of a protozoa?
Cysts
