What is the definition of Monera?
The Monera are a group of prokaryotic organisms that are generally unicellular and lack membrane-bound organelles. They are typically characterized by a rigid cell wall and a lack of nuclear membrane. Kingdom Monera – Definition Characteristics .
Characteristics of Monera
The Monera are a group of prokaryotic organisms that lack a nucleus and other membrane-bound organelles. They are most commonly unicellular, but some are multicellular.
The Monera are a very diverse group of organisms, and their characteristics vary greatly. Some members of this group are photosynthetic, while others are chemosynthetic, Some are aquatic, while others are terrestrial. Some are parasites, while others are free-living.
One common characteristic of all Monera is their lack of a nucleus and other membrane-bound organelles. This lack of a nucleus is what distinguishes them from other prokaryotes. Monera also lack a cell wall, which is another distinguishing characteristic.
Most Monera are unicellular, but there are a few multicellular species. One example of a multicellular Monera is the slime mold.
Some of the most well-known members of this group are the bacteria.
Bacteria
are very small and simple organisms that can only be seen with a microscope. They are single cells that can reproduce quickly. Bacteria can cause diseases in people and animals.

Structure of Bacteria
There are many types of bacteria, but all share some common features. Bacteria are single-celled organisms that are too small to be seen with the naked eye. They are prokaryotes, meaning they lack a true nucleus. Bacteria also have a cell wall and a plasma membrane. The cell wall is a tough, outer layer that helps protect the bacteria from predators and environmental stress. The plasma membrane is the inner layer that surrounds the cell and controls what enters and leaves the cell.
Bacterial Shape
There are many shapes of bacteria, but most are spherical, rod-shaped, or spiral. The shape of a bacterium is important for its ability to move and interact with its environment.
Classification of Monera
There are three domains of life: Archaea, Bacteria, and Eukarya.
Bacteria have single-cell. They don’t have nucleus. They are classified by their shape and the presence of a cell wall.
The three main shapes of bacteria are coccus (spherical), bacillus (rod-shaped), and spirillum (spiral-shaped).
Bacteria are further classified by the presence or absence of a cell wall.
Gram-positive bacteria have a thick cell wall that retains the purple dye Gram stain.
Gram-negative bacteria have a thin cell wall that does not retain the purple dye Gram stain.
Monera is a kingdom of prokaryotic organisms that includes both bacteria and archaea.
The two main groups of bacteria are gram-positive and gram-negative.
Gram-positive bacteria have a thick cell wall that retains the purple dye Gram stain.
Gram-negative bacteria have a thin cell wall that does not retain the purple dye Gram stain.
