Bacteria are microscopic organisms having the shape of rod, sphere, or spiral. The bacteria lack predefined nuclei and membrane-bound organelles.

Bacteria are prokaryotic organisms with the absence of a well-defined system for performing specific tasks.

The bacteria are the smallest single-celled organisms that can not be viewed by naked eyes.

The bacteria are classified based on their shapes. They can be spherical, rod and spiral.

The bacteria are not present in complex shapes such as prism, cone, or spiral.

The nuclei and membrane-bound organelles are the characteristics of eukaryotic organisms. The bacteria being the primitive organisms lack the well-defined nucleus and membrane-bound organelles.

Thus bacteria are microscopic organisms having the shape of rod, sphere, or spiral. The bacteria lack predefined nuclei and membrane-bound organelles.
