Understanding the Kingdom Monera

The video discusses the Kingdom Monera, which includes single-cell organisms found almost everywhere on Earth. These organisms lack a nucleus and are classified as prokaryotes. Bacteria, a major group within Monera, obtain energy through various methods and are crucial for life on Earth. The kingdom is divided into archeabacteria, found in extreme environments, and bacteria, which are widespread. Bacteria play essential roles in digestion, the nitrogen cycle, and food production. They are classified by shape and reproduce mainly asexually through binary fission, with some engaging in sexual reproduction via conjugation.

What type of organisms make up the Kingdom Monera?

• Multicellular organisms
