11In the laboratory, cells are normally placed in a(n) [blank_start]isotonic[blank_end] solution.
- Aisotonic
12In animal cells, shriveling of the cell due to water leavin the cell when the environment is hypertonic is called [blank_start]crenation[blank_end].
- Acrenation
13Facilitated transport is a form of [blank_start]passive[blank_end] transport.
- Apassive
14In a [blank_start]hypotonic[blank_end] solution, vacuoles fill with water, turgor pressure develops, and chloroplasts are seen next to the cell wall.
- Ahypotonic

- ACarrier proteins
