20 Questions
Which science deals with the study of microorganisms and their activities?
Microbiology
Why were microorganisms initially placed in either the plant or animal kingdom?
Because they possess both plant-like and animal-like characteristics
Why are viruses not included in the kingdom Protista?
Because they are not technically alive

By their structural and functional characteristics
What is the main difference between a cell and an organelle?
A cell is the basic unit of life, while an organelle is a specialized subunit within a cell
What is nucleoplasm and where is it found?
A gelatinous liquid that supports chromosomes and nucleoli; found enveloped by the nuclear envelope
