Chapter 11, Problem 2
For each of the following statements that is true, write “true” in the blank. For each statement that is false, write the word(s) that should be substituted for the underlined word(s) to make the statement correct.
__________ A bacillus is a bacterium with a slightly curved rod shape.
Verified step by step guidance1
Step 1: Understand the term 'bacillus' in microbiology. A bacillus refers to a bacterium that has a rod-shaped morphology, which is typically straight rather than curved.
Step 2: Recognize that a bacterium with a slightly curved rod shape is not called a bacillus but rather a 'vibrio'. Vibrios are comma-shaped or curved rods.
Step 3: Identify the underlined word(s) in the statement, which is 'bacillus', and determine if it correctly describes a slightly curved rod-shaped bacterium.
Step 4: Since 'bacillus' refers to straight rods, replace the underlined word 'bacillus' with 'vibrio' to make the statement true.
Step 5: Write the corrected statement: 'A vibrio is a bacterium with a slightly curved rod shape.'

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Bacterial Morphology
Bacterial morphology refers to the shape and arrangement of bacterial cells. Common shapes include cocci (spherical), bacilli (rod-shaped), and spirilla (spiral-shaped). Understanding these shapes helps in identifying and classifying bacteria.

Types of Bacterial Cell Morphology
Definition of Bacillus
A bacillus is a bacterium that has a straight rod shape, not curved. The term 'bacillus' specifically denotes rod-shaped bacteria, which can vary in length and width but are generally straight rather than curved.

Curved Rod Bacteria
Bacteria with a slightly curved rod shape are called vibrio. Vibrio species are comma-shaped and differ from bacilli by their curved morphology, which affects their motility and ecological niche.
