Amoeba

One example of a cell that can live on its own is an "organelle." Organelles are found inside eukaryotic cells and perform specific functions to keep the cell alive and functioning properly.
they can make their own food and adapt to their environment
paramecium cells can not survive on its own because it works as a group while on the other hand, the Elodea cells can live on their own because they are single cells.
no because it is part of a much larger being
Nothing smaller than a cell that can live on its own has ever been discovered. Viruses, for example, while smaller than a cell, cannot live on its own. It it not even sure that viruses are more than a dot of inert chemical.
No, cells from the elodea plant are not organisms because they cannot live on their own like the paramecium.
yes because of all the amoeba in the ocean. The single celled organism is the simplest out their.
yes cell wall has its own wall
