Detailed explanation-1: -Rocks do not reproduce, they do not die, and therefore they were never alive. But the line is not always that clear. Life is the process of self-preservation for living beings and can be recognised by life processes; such as eating, metabolism, secretion, reproduction, growth, heredity etc.
Detailed explanation-2: -Rocks do not have cells. Only living things have cells and rock is a non living thing. You can read about the Plant Tissues – Classification, Definition, Types in the given link.
Detailed explanation-3: -Rock is a non-living thing. A living organism shows signs of life. It grows or moves or feeds. Rock does none of them, so it is not a living organism.
Detailed explanation-4: -Instead of cells, a non-living thing is made up of elements or compounds that form from chemical reactions. Examples of non-living things are rocks, water, and air.
Detailed explanation-5: -Viruses, virions, and viroids are all examples of non-cellular life. Viruses are parasites that infect plants, animals, fungi, and bacteria.
