That would depend on:
A rotting tomato cell is alive. Just because it is rotting it doesn't mean it is dead.
multicellular organisms are alive
alive - unicellular means they only have one cell but that doesn't mean their dead
Because they are alive and useful
live
you should know that they are all going to kill you!
you dead and get sick

If a cell can possibly be alive, then it certainly can be dead.
alive - unicellular means they only have one cell but that doesn't mean their dead
Plant roots are organic, dead or alive.
You bury a plant when it's alive and dig it up when it's dead.
Because they are alive and useful
live
not if its all dead use a defibrillator
There will be no photosynthesis.Plant will be dead.

It should be obvious that all cells must be alive at some point, since they are created biologically rather than in factories, and they also die eventually. The presence of cilia does not indicate whether a cell is alive or dead. Cilia are just part of the cell, normally used for locomotion.
