Rocks are not made of cells. Cells are the fundamental building blocks of life and are only found in living organisms.

Rocks are made of minerals, which are naturally occurring, solid, inorganic substances with a defined chemical composition and a characteristic crystalline structure. These minerals are formed through various geological processes, such as crystallization from magma or lava, precipitation from water solutions, or transformation of other minerals.

Here's a simple breakdown:

* Living organisms: Made of cells.

* Rocks: Made of minerals.

So, while rocks are fascinating and complex, they are not alive and don't contain cells.
