In engineering a rigid structure is something that is analyzed as if none of the components deform, that is bend, compress or stretch. For example when analyzing a bridge made out of riveted beams to see how much force is on the joints, the assumption is often made that when there's a load on it, it doesn't deform, that is all the beams stay the same length and don't bend. This isn't exactly true in real life, but it's a good enough approximation that the force on the joints can be pretty accurately calculated.
The reason this approximation is used is that it would be extremely difficult to calculate the exact deformations and for things like bridges the margin for error in doing the design is very large. The errors caused by the rigid assumption are much smaller than the margin for safety engineered into the structure.
For designing things like a bungee jumping tower, treating the cord as a rigid structure is probably not a very good idea.
There are three states of matter, solid, liquid and gas. The state of matter wherein particles are fixed in a rigid structure is solid.
Cell wall
Mainly it is the cell wall. It surrounds the cell
Pinus is the scientific name for the genus of pine trees. The structure of pine trees is long rigid needles.
plant cell walls are made of cellulose, which makes them rigid
The difference between a structure that is rigid and one that is flexible is that the rigid structure will not bend or flex when force is applied. A structure that is rigid cannot flex.
An animal cell's structure is flexiable while a plants cell's structure is rigid
The cell wall is a rigid supporting structure.
There are two: the c double bonded to o parts and the ring structure.

it was rigid and well defined.

Because they are 80% water and have no rigid structure
it was rigid and well defined.
