Biologists have been able to keep isolated chloroplasts or mitochondria for a few hours or days. can these structures be
considered alive?

Isolated chloroplasts or mitochondria cannot be considered alive, because although they can survive while isolated for a few hours or days and they resemble that of an independent cell (which are alive), they don't metabolise energy, and they don't have cells.

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics

where is the scientific experiment?
