Study Notes
Characteristics of Kingdom Monera
- Organisms in Kingdom Monera are typically unicellular and prokaryotic.
- They lack membrane-bound organelles, which distinguishes them from eukaryotic organisms.
- Commonly found characteristics do not include complex cellular structures like a nucleus or mitochondria.
Cellular Structure in Monera
- All Monera organisms lack a true nucleus (nuclear envelope), containing their genetic material in a nucleoid region instead.
Groups Included in Kingdom Monera
- Kingdom Monera includes two main groups: Bacteria and Archaea.
- Bacteria are further classified into various groups, such as cocci, bacilli, and spirilla based on shape.
Nutrition in Monera
- Most Monera organisms obtain nutrition through various modes, including photosynthesis, chemosynthesis, and heterotrophy.
- Some bacteria are autotrophic, generating energy through chemical means or light.
Reproduction in Monera
- The primary method of reproduction in Monera is asexual, predominantly binary fission.
- This process involves the division of a single organism into two identical daughter cells, allowing rapid population growth.
