A cell membrane (a cell wall in plants). Ribosomes are found in prokaryotic cells, and eukaryotic cells have such features as the nucleus, vacuoles, and mitochondria, as well as many specialized organelles.

The outside covering that all plant cells have and that is not found in animal cells is called a cell wall. The cell wall provides structure, support, and protection to the plant cell, allowing it to maintain its shape and resist mechanical stress.
The cell structure found in plant and bacterial cells but not animal cells is the cell wall. This rigid structure provides support and protection to the cell, maintaining its shape and preventing it from bursting in a hypotonic environment.
While cell membranes might be around every cell, cell walls made of cellulose are only found around plant cells. There are other sorts of cell walls. Many but not all bacteria also have a structure called a cell wall.Fungi and some protozoa also have cell walls. These walls are made of proteins. They serve the same purpose of protecting and maintaining structure.
The nucleus is a double-membraned organelle found in all eukaryotic cells. It is the largest organelle, which functions as the control centre of the cellular activities and is the storehouse of the cell’s DNA. By structure, the nucleus is dark, round, surrounded by a nuclear membrane.
No, human cells do not have cell walls. Instead, human cells are surrounded by a cell membrane, which helps to maintain cell structure and regulate the movement of substances in and out of the cell. Cell walls are typically found in plant cells and some bacteria.
