Study Notes
Introduction to Bacteria
- Bacteria are unicellular organisms classified as prokaryotes, meaning they lack a true nucleus and certain organelles.
- These microorganisms are metabolically active and reproduce through binary fission, a simple division process.
- Bacteria are significant in medicine, being a primary cause of various diseases.
- While they may appear simple, bacteria are actually complex and highly adaptable life forms.
- Bacteria thrive in diverse environments, existing in massive numbers both in and on other organisms and in various habitats.
- Generally, bacteria can be categorized as harmful or beneficial; most play vital roles in supporting other life forms and are integral to industrial and medicinal applications.
Classification of Bacteria
- Classification hinges on several factors:
- Shape of the bacteria (e.g., cocci, bacilli, spirilla).
- Composition of the cell wall (e.g., Gram-positive vs. Gram-negative).
- Mode of respiration (aerobic vs. anaerobic).
- Mode of nutrition (autotrophic vs. heterotrophic).
