Characteristics of Kingdom Monera
In this article we will discuss about characteristics of kingdom monera
Characteristics of Kingdom Monera
- Most Monera are single-celled organisms, like bacteria and archaea.
- Members of the Kingdom Monera can be found almost anywhere. They also live in harsh environments such as hot springs, deserts, snow, and deep seas.
- Their body structure is very simple, but they are complex in behavior and show metabolic diversity.
- The bacterial cell reveals three layers: capsule, cell wall, and cytoplasm.
- A thick layer of glycocalyx bound tightly to the cell wall is called a capsule, and this cell wall protects from desiccation and antibiotics.
- The cell wall is made up of non-cellulosic material called peptidoglycan.
- Genetic material is naked DNA, known as nucleoid.
- Histones, nuclear envelope, nucleoplasm, nucleolus, and chromatin are absent.
- All membrane-bound organelles are absent.
- Contains 70s type of ribosomes
- Since mitochondria are absent, respiratory enzymes are associated with the plasma membrane.
- Some bacteria have extrachromosomal DNA molecules that are called Plasmids.
- Some Monera are autotrophs, producing their food through photosynthesis or chemosynthesis, while others are heterotrophs, relying on organic matter for nutrition.
- They reproduce asexually through binary fission, where a cell divides into two identical cells, ensuring rapid population growth.
