On the list of defining attributes of animals is their capacity to respond swiftly to variations within the setting, facilitated by their well-produced sensory and anxious systems.
The cell wall can also be lacking. Consequently, an animal cell inside a hypotonic solution will swell and inevitably burst (lyse) because it lacks the cell wall that forestalls lysis through extreme osmosis.
