Yes, all animals and plants that exist have cells. The only living things that do not have cells are viruses and perhaps prions.
No prions are composed of protein - they are nonliving.
no otherwise it would be considered living
They are considered living.
Lettuce is a plant, and plants are living things.
An organism is any living thing (i.e. it fits all the criteria required for something to be considered "living"). Examples include bacteria, plants, fungi, protists, and animals. Be careful though, because viruses and certain other infectious agents, like prions and viroids, are not officially considered living things by all scientists.
It is somewhat doubtful whether viruses and prions can be considered living things. They have some characteristics of living things, but lack others.A fire can reproduce. Several types of computer programs, and especially malicious programs, can reproduce. I believe some of the figures in Conway's Game of Life can reproduce.

Cells are called the basic unit of life because, all living things come from other living things.cells are called the basic units of life, because all living things are made from cells. (some living things are unicellular,have 1 cell, and some living things are multicellular,have more than 1 cell) human beings are multicellular, while bacteria are unicellular.
No prions are composed of protein - they are nonliving.
Basically all living organism must have at least one cell to survive and to carry out its function.Organism like virus, viriods or prions are not considered as living organism as they can't carry out its function outside the host cell.
Viruses are not considered living organisms but can cause disease. Prions that cause Bovine Spongiform Encephalopathy (Mad Cow disease, aka vCJD- variant Creutzfeld-Jakob disease when in humans) are not living organisms as they are just misfolded protein particles.
no otherwise it would be considered living
Yes they do if not fire along with many other things would be considered living.
They are considered living.
Because cars are not living things. organisms are living things.
Lettuce is a plant, and plants are living things.
