What are tissues composed of?

Cells
Atoms
Molecules
Organs

The correct answer is: Cells

Tissues are groups or layers of cells that work together to perform a specific task or function in the body. Cells are the fundamental unit of life and are responsible for carrying out the essential processes in all living organisms. While atoms and molecules make up cells, they are not composed of tissues themselves. Organs are also not composed of tissues, as organs are made up of different types of tissues working together. Therefore, A is the only correct answer as it directly explains what tissues are actually made of.
