Why is the cell the smallest structural and functional unit of an organism?

Answer 1

Cell is the structural and functional unit of an organism, i.e., it is the basic unit of structure.

This is because a cell in itself is the smallest part of an organism, which is capable of functioning independently and can carry out the fundamental duties of life like reproduction (by cell division - mitosis, meiosis, amitosis), metabolism (photosynthesis and/or respiration)

Answer 2

Cells contain all the necessary components to carry out the basic functions of life, such as obtaining nutrients, metabolizing them, and reproducing. They are small enough to efficiently transport substances in and out, while also being able to regulate their internal environment. This makes them the fundamental building blocks of all living organisms.

Answer 3

Bcos it's the building block of the organism!
