What are cells described as?

The basic units of living matter
Small organs in the body
Units of chemical reactions
Building blocks of proteins

The correct answer is: The basic units of living matter

Cells are described as the basic units of living matter because they are the smallest structural and functional unit of all living organisms and are responsible for carrying out all processes necessary for life. Option B is incorrect because cells are not organs, and organs are made up of cells. Option C is incorrect because while cells do carry out chemical reactions, they are not solely defined as units of chemical reactions. Option D is incorrect because while cells do build proteins, they are not solely defined as building blocks of proteins.
