The particles in most solids from structural units called crystals. Crystals are a solid substance that have a geometrically shaped form.

for this reason ceall are called structural and functional units of life
Network solids are composed of an extended three-dimensional network of atoms bonded together by covalent bonds. Examples include diamond and quartz. The structural units in network solids are individual atoms or small groups of atoms connected to each other in a repeating pattern throughout the solid.
In network solids, the basic structural units are atoms or ions held together by covalent bonds to form a three-dimensional network structure. These units are interconnected through strong chemical bonds in all directions, creating a continuous lattice structure. Examples of network solids include diamond (carbon atoms) and quartz (silicon and oxygen atoms).
Cells are smaller than particles. Cells are the basic structural and functional units of living organisms, while particles refer to tiny pieces of matter, which can include molecules, atoms, or subatomic particles.
Carbohydrates are polymers formed of structural units called monosaccharides, which are simple sugars such as glucose, fructose, and galactose. These monosaccharides can link together to form more complex carbohydrates like disaccharides (e.g. sucrose) or polysaccharides (e.g. starch).
The structural units are the heart,blood, and blood vessels
