35 Bacterial Cells Diagram For Structure And Function

Depending on the presence of nuclei inside cells, there are two types of cellular world, eukaryotic and prokaryotic cells. There is a well-defined nucleus surrounded by a nuclear envelope in eukaryotic cells while this compartment is not available in prokaryotic cells. Prokaryotes are all bacteria. Take a close look to bacterial cells diagram to learn their structure and function of bacteria.

The look of bacteria

There are different shapes and arrangements of bacterial cells diagram when observing bacteria with microscope. Bacterial morphologies include Spherical (Coccus), Rod-shaped (Baccilus), Curved (Vibrio, Spirochaete), Star-shaped (Stella), and Square-shaped (Arcula). There are different arrangements of these cells of different prokaryotic species after cell division either they are pair, chain or cluster.

0.2 µm and 700 µm are ranges of bacteria size in diameter. Their exceptional features of growth make them around 10 times tinier than eukaryotic cells. They have apparent benefits such as faster growth, higher nutrient acceptance rate, and significantly shorter life cycle due to their small surface-to-volume meaning they have more surface area comparative to cell volume than large cells do. They can divide very rapidly for example, E.coli divides every 20 minutes when seeing bacterial cells diagram. This results to occurrence of mutations in bacterial genes in higher chance. This allows bacteria to explore new habitats much more quickly than eukaryotic cells as they can acclimatize rapidly with fluctuating environmental situations.

Cell wall

Physical damage and osmostic shock can be absorbed by the cell wall of bacteria to protect the cell. This is also used to keep shape of bacterial cells and stiffness. In bacterial cells diagram, there are two groups of bacteria, gram-positive and gram-negative vary in certain properties bacterial cell walls although they all consist of mucopeptide or murein or peptidoglycan.

Cytoplasmic membrane

In the bacterial cells diagram, the cytoplasm is surrounded by the cytoplasmic membrane that controls the particular transference of ingredient between the environment and the cell. Lipid and protein are 2 main components available in the cytoplasmic membrane. Phospholipid bilayer is the lipid element of the bacterial cell. Through particular contacts with phospholipid molecules, in different locations within the membrane, there are membrane proteins that consist of 3 main groups with unique roles in cellular activities, the outer-surface proteins, integral proteins, and inner-surface proteins.

Integral proteins have 3 main mechanisms namely symport, uniport, and antiport to deliver substance through the cytoplasmic membrane in and they are definitely fixed in the membrane. Outer-surface proteins work together in the delivery of big molecules into the cells with periplasmic proteins and they are typically in Gram-negative bacteria.    Inner-surface proteins involve in energy compliant responses and also other vital cellular tasks when working with other proteins in bacterial cells diagram.
