What is the function of a contractile vacuole? Why do some protists need these?

Regulates the amount of water in the organism. Without them the organism might overpressurize and explode.

Why do the ciliates have two nuclei? What is the purpose of each?

They need 2 nuclei because they require such a large amount of energy to live, primarily b/c of the beating cilia. Macronucleus control metabolism, while micronucleus controls reproduction.

What is a mycelium? Describe its function.

interwoven hyphae that forms body of fungus
