Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Bacteria have three shapes. Which of the following is not a common shape of bacteria?

A	Spirilla
B	Cocci
C	Bacilli
D	Cube

Explanation:

Detailed explanation-1: -The correct option is c, oval. The cell shape is the characteristics of the bacterial species and bacteria are grouped under four categories based on their cell shape; spherical (coccus), rod-shaped (bacillus), comma-shaped (vibrium) and spiral (helical or spirillum). The bacterial cell does not have an oval shape.

Detailed explanation-2: -The three basic shapes of bacteria are bacillus (rod-shaped), coccus (spherical-shaped), and spirillum (spiral-shaped).

Detailed explanation-3: -The three basic shapes of bacteria are Cocci (round), Bacilli (rod), and Spirilla (spiral). When viewed under light microscope, most bacteria appear in variations of three major shapes: the rod (bacillus), the sphere (coccus) and the spiral type (spirillum).

Detailed explanation-4: -Bacteria occur in a variety of shapes like spherical, rod, spiral, sheathed, stalked, filamentous, square, star, spindle, lobed. Triangular bacteria have not been discovered yet. Q.
