Cells: How Can Something Small Have a Large Impact?

Cells are the fundamental units of life, present in all living organisms. There are two main types of cells: prokaryotic, which are simpler and found in bacteria, and eukaryotic, which are more complex and make up plants, animals, and humans. Eukaryotic cells work together to form tissues and organs, maintaining homeostasis. Bacteria, a type of prokaryote, can have significant effects on humans and animals, causing illnesses like tuberculosis and food poisoning. Despite their small size, cells have a profound impact on life, prompting further exploration of their capabilities.
