Homeostasis and Cells (p. 214-217)
1.
The term ___________________________ refers to the relatively constant internal physical and chemical state of a living
cell.
2. Unicellular prokaryotes, called ___________________________, are adapted to living in a remarkable number of different
places.
3. Some unicellular eukaryotes, called ___________________________, contain chloroplasts.
