Answered by GPT-4o mini
The tiny structural unit you are referring to is called a **cell**. Cells are the basic building blocks of all living organisms. In animal cells, they are enclosed by a plasma membrane, while in plant cells, they are surrounded by a rigid cell wall in addition to the plasma membrane. Cells contain cytoplasm, organelles (such as the nucleus, mitochondria, and ribosomes), and other components necessary for various biological functions.
