What is a bacterial structure?
The structure of bacteria is easier than the structure of other organisms. Bacteria are microorganisms that lack organelles bound to the membrane and a well -defined nucleus. They usually accept one of four shapes, depending on the type of bacteria and have numerous attachments with different functions.
bacteria are unicellular, which means they consist of only one cell. In this single cell, everything that bacteria need to survive and reproduction, except for food, is contained. As such, the bacterial structure has developed ways that allow cells to effectively do business.
bacteria are prokaryotes, which means they have no organized core. Nucleus is an organelle in which deoxyribonucleic acid (DNA) and genetic materials are necessary for replication in more developed cells. Despite the absence of the nucleus, bacteria still have DNA, but float freely in the cytoplasm.
The cell wall surrounds the cytoplasmic area or the interior of the bacteria and acts as a support structure CElé organism. The base layer of the cell wall consists of peptidoglycan, a molecule that consists of amino acids and sugars. This is a feature unique to bacteria and is what causes the cell wall to be both internal and outer and outer pressure resistant.
Peptidoglycan gives the bacteria its shape. The shape of the cell is usually different to this species and is an important detail in identifying an unknown species. Two common bacteria shapes are bacillus, which has a stick shape, and a Spirillum, which is in the shape of a spiral. Other common forms are cocoon or spherical and fibrous, in which individual cells grow in length, but do not separate.
The cell wall line is a membrane that selectively allows molecules to and out of the cell. Cytoplasm fills the area inside the cell membrane. Within the cytoplasm there are chromosomes, DNA cells. Cytoplasm also contains ribosomes that create proteins used by the cell.
On the outside of the cell wall, there are different enlargements that help bacteria effects such as movement and attachment to other objects. Flamella, protein fibers, are located on the outside of the body and move bacteria through their environment. Bacteria can have one or many flagella depending on the species.
Another surface feature of bacteria is Fimbrae. These protein fibers are used by bacteria to connect to other structures. They exist on the whole surface of bacteria and are much smaller than flagella. The third component is an extension of a protein similar to a fiber called Pilus, also found on the outside of the cell. Pili AID in bacterial conjugation and connection.
