Diatoms are single celled algae. They have a silica - based cell wall called a frustule, which gives each diatom a particular shape.
Diatoms exist as separate single cells although some may be found in groups or colonies. The ones found in colonies create very pretty forms: leaf shaped, oval , star and even like a period.
Outer shells of diatoms are quite valuable. They are used in industry in the manufacture of toothpaste to give it grit.

Diatoms have cell walls composed of silicon dioxide.
The range of cells receiving the content of copied cells is called the destination area. The correct option is a.
The smallest unit of life is a cell. It is composed of biomolecules. Every living thing is composed of several cell units. Different sorts of creatures contain various types of cells.
The cell divides to form the other cell. This process if called cell division. Cell division occurs during mitosis. All eukaryotic cells go through the process.
There are four stages to the process. The cell divides during the procedure. A daughter cell that is identical to the parent cell is created.
The destination region refers to the set of cells that will get copied cell content. The cell copies the full contest for another cell.
Thus, the correct option is a. destination area.
