Biologically the answer is cell since a group of cells working together for a purpose is reffered to as a tissue. Since you are asking for the smallest level, phisically, it can also be atoms.
Tissues are organized into organs. Cells organized into tissues Tissues organized into organs Organs organized into organ system

A chromosome is made up of DNA, which has subunits called nucleotides.
Nonmetal atom
Organisms are made of basic units called cells. These cells are found in every part of the organism's organs and tissues.

All tissues in the body are made up of cells. Cells are the basic structural and functional units of living organisms and are organized into specialized groupings to form tissues with specific functions.
Cells are the basic functional units of living things. A groups of cells together forms a tissue. A group of tissues together forms an organ.

Cell. Cells are the basic structural and functional units of life, and they make up tissues, organs, and organisms.
Cells are the basic structural and functional units of all living things, while tissues are groups of cells that work together to perform specific functions within an organism. Tissues are made up of cells, and cells are the building blocks of tissues. Both cells and tissues are essential for the proper functioning of an organism.
Cells are the basic functional units of living things. A groups of cells together forms a tissue. A group of tissues together forms an organ.
cells make tissues
No. Atoms make up molecules which make up cells which make up tissues which make up organs which make up organ systems which make up organisms.
The two main components of all tissues are cells (which are the basic structural and functional units) and the extracellular matrix (which is the material that surrounds and supports the cells). Together, cells and the extracellular matrix give tissues their structure and function.
It all depends... Cells vary from size to size. The largest cell is an ostrich egg which is larger than most tissues, however tissues are made from cells working together to achieve a common purpose. If it is a multicelled organism than the cells will be smaller than it's own tissues.
