Domain-Prokarya Overview

Prokaryotic cells possess a cell wall and cell membrane, which are essential for maintaining structure and integrity.
They lack a nucleus, differentiating them from eukaryotic cells.

Harmful Bacteria

Certain prokaryotes can cause various harmful conditions, including:
- Tooth decay
- Acne
- Streptococcus infections
- Food poisoning

Beneficial Bacteria

Prokaryotes play important roles in various beneficial processes:
- Fermentation in food production (e.g., cheese)
- Acting as decomposers in ecosystems
- Production of medicines, such as antibiotics

Bacterial Shapes

Prokaryotes can be classified by their shapes:
- Cocci: spherical shape; the term "strep" refers to a chain formation of cocci.
- Bacilli: rod-shaped bacteria, commonly involved in various infections.
- Spirilla: spiral-shaped bacteria, known for their unique movements.

Bacterial Processes

Pasteurization is a method used to eliminate harmful bacteria from food and beverages, ensuring safety.
Endospores are a robust survival mechanism produced by some bacteria, allowing them to withstand harsh conditions.
