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.
A rigid structure takes up more space than a fluid structure because the molecules in a rigid structure are locked in place and cannot move past each other easily. In contrast, the molecules in a fluid structure can flow and change position, allowing them to occupy less space and adopt the shape of their container.
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
The rigid helix structure is found in spirochetes, which are spiral-shaped bacteria characterized by their flexible, corkscrew-like shape that allows them to move in a corkscrew motion. Spirilla, on the other hand, are spiral-shaped bacteria with a more rigid structure that do not exhibit the same flexible helical shape as spirochetes.
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.
Diamond is the allotrope of carbon that has a three-dimensional rigid structure. Its strong covalent bonds between carbon atoms form a rigid, tetrahedral structure, making diamond extremely hard and durable.
There are two: the c double bonded to o parts and the ring structure.

The cell wall is a rigid supporting structure.
Because they are 80% water and have no rigid structure

Blimps are non-rigid airships with an envelope that maintains their shape, while dirigibles are semi-rigid or rigid airships with a structure inside the envelope to maintain their shape. Dirigibles are typically larger and have more internal structure for support and control.
