The rigid non-living boundary found only in plant cells is the cell wall. It provides support and protection for the cell, allowing plants to maintain their structure and shape. The cell wall is composed primarily of cellulose.
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.
Echinoids have a hard endoskeleton composed of calcareous plates called ossicles, which form a rigid structure to protect their internal organs and provide support for movement and feeding.

Mainly it is the cell wall. It surrounds the cell
The rigid structure found outside the plasma membrane in bacterial cells is called the cell wall. It provides structural support and protection to the cell.
The rod-shaped structure of tightly coiled DNA found in the cell nucleus of plants and animals is called a chromosome.
The rigid non-living boundary found only in plant cells is the cell wall. It provides support and protection for the cell, allowing plants to maintain their structure and shape. The cell wall is composed primarily of cellulose.
An organelle called the nucleus is where DNA is found in plants and animals.

The rigid covering mainly found around plant cells and some bacteria is called a cell wall.

In flowering plants, the egg is called the ovule and is found in the ovary, usually at the base of the pistil.
