Bacilli
The rod-shaped structure of tightly coiled DNA found in the cell nucleus of plants and animals is called a chromosome.
Mainly it is the cell wall. It surrounds the cell
The organelle called a chloroplast.
The organelle called a chloroplast.
Chlorophyll is found in a cell structure called a chloroplast, which is responsible for photosynthesis in plants. Chloroplasts contain chlorophyll pigments that capture light energy and convert it into chemical energy to produce food for the plant.
Cell wall and chroloplasts
The cell wall is a rigid supporting structure.
It is called the cell wall.
The structures found inside a cell are called organelles. These organelles carry out specific functions that are essential for the cell to survive and perform its various roles in the body. Examples of organelles include the nucleus, mitochondria, and endoplasmic reticulum.
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.
Membranes do not have a stiff outside. I suspect the answer you are looking for is the cell wall, which is a stiff structure found outside the cell membrane of a plant cell, but separate from it.
This structure is called a cell wall and it is found in plant cells and bacteria cells.
