one-celled living organisms classified by their body shpae
A
virus
B
bacteria
C
spirilla
D
flagella
Explanation: 

Detailed explanation-1: -The structure of bacteria is known for its simple body design. Bacteria are single-celled microorganisms with the absence of the nucleus and other cell organelles; hence, they are classified as prokaryotic organisms.

Detailed explanation-2: -Bacteria are classified into five groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters. Bacteria are found in every habitat on Earth: soil, rock, oceans and even arctic snow.

Detailed explanation-3: -Bacteria are single celled microbes that lack a nucleus. Archaea are like bacteria, but they have different structures and properties. This gives them the ability to live in extreme environmental conditions.

Detailed explanation-4: -Ferdinand Julius Cohn (January 24, 1828 – June 25, 1898) was a German biologist. His classification of bacteria into four groups based on shape (sphericals, short rods, threads, and spirals) is still in use today.

Detailed explanation-5: -Simply put, bacteria with different shapes present different physical features to the outside world, and these features help cells cope with and adapt to external conditions.
