The Cell Wall of Bacteria

Bacteria are protected by a rigid cell wall composed of peptidoglycans.

LEARNING OBJECTIVES

Recall the characteristics of a bacterial cell wall

KEY TAKEAWAYS

Key Points

A cell wall is a layer located outside the cell membrane found in plants, fungi, bacteria, algae, and archaea.

A peptidoglycan cell wall composed of disaccharides and amino acids gives bacteria structural support.

The bacterial cell wall is often a target for antibiotic treatment.

Key Terms

binary fission: The process whereby a cell divides asexually to produce two daughter cells.

Bacterial Cell Wall: The anatomy of bacterial cell structure.

Bacterial cells lack a membrane bound nucleus. Their genetic material is naked within the cytoplasm. Ribosomes are their only type of organelle. The term “nucleoid” refers to the region of the cytoplasm where chromosomal DNA is located, usually a singular, circular chromosome. Bacteria are usually single-celled, except when they exist in colonies. These ancestral cells reproduce by means of binary fission, duplicating their genetic material and then essentially splitting to form two daughter cells identical to the parent. A wall located outside the cell membrane provides the cell support, and protection against mechanical stress or damage from osmotic rupture and lysis. The major component of the bacterial cell wall is peptidoglycan or murein. This rigid structure of peptidoglycan, specific only to prokaryotes, gives the cell shape and surrounds the cytoplasmic membrane. Peptidoglycan is a huge polymer of disaccharides (glycan) cross-linked by short chains of identical amino acids (peptides) monomers. The backbone of the peptidoglycan molecule is composed of two derivatives of glucose: N-acetylglucosamine (NAG) and N-acetlymuramic acid (NAM) with a pentapeptide coming off NAM and varying slightly among bacteria. The NAG and NAM strands are synthesized in the cytosol of the bacteria. They are connected by inter-peptide bridges. They are transported across the cytoplasmic membrane by a carrier molecule called bactoprenol. From the peptidoglycan inwards all bacterial cells are very similar. Going further out, the bacterial world divides into two major classes: Gram positive (Gram +) and Gram negative (Gram -). The cell wall provides important ligands for adherence and receptor sites for viruses or antibiotics.

If a device turned on then electrical currents flow through the device by which,

When a device that runs off of electricity is turned on, the flow of electrons is mediated through the process known as electric current.

Electricity may be defined as a type of energy that typically results from the existence of charged particles like electrons or protons. It is a secondary source that commingles from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power, etc.

This flow of electrons also induces the formation of magnetic fields which involves the liberation of energy at once in the form of immobile electricity. All this process is obviously mediated by an electric switch that is responsible for breaking or closing an electric circuit.

Therefore, when a device that runs off of electricity is turned on, the flow of electrons is mediated through the process known as electric current.

Answer:

Answer: Four sperm cells.  

Explanation:

Explanation: Meiosis is is a cell division process that generates four haploid cells (gametes) from a single diploid germline cell.

In the drosophila fruit fly, four haploid sperm cells are produced from a single original parent cell. The germ cells undergo meiosis to form gametes. Thus, the correct option is C.

Meiosis is the reductional division through which four daughter cells are produced from a single parent cell. The gametes are produced from meiosis. The gametes produced from a diploid cell are haploid in the number of chromosomes in cells. Both male and female gametes undergo fertilization to form diploid zygote.

Meiosis is divided into two parts- Meiosis I and Meiosis II. Both the parts comprises of four phases- Prophase, Metaphase, Anaphase, and Telophase. The chromatids undergo crossing over with non-sister chromatids to form recombination in cells.

Therefore, the correct option is C.

Answer:

Fume Hoods

Fume hoods provide a barrier between laboratory workers and hazardous chemicals or chemical processes. The key item of fume hoods to make it function well is its ability to exhaust vapor/gas at a certain flow rate.

Flammable Liquid Storage Cabinets

Fire hazard from flammable liquid shall be adequately controlled, including by using storage cabinets. Always store the flammable liquid inside the storage cabinet.

Fire Extinguishers

Provide appropriate fire extinguishers for the laboratory in adequate quantity. Place them in the right location for easy access, high visibility, and free from any obstacles.

Fire Blankets

A fire blanket is one of the most important fire extinguishing equipment. When you find a fire for the first time, use this fire blanket to diminish the fire as soon as possible before it grows bigger.

Safety Cans

You must use safety cans to store flammable liquid in the laboratory safely. It minimizes fire accidents and so protect laboratory workers from the fire hazards.

Safety Showers

When chemical splash occur, you have to immediately wash all of your work cloth and body with plenty of water. So, that’s why safety showers role are very important in case of such emergency condition.

Eyewash Stations

Even though you have already worn safety goggle, but it does not mean that your eyes are fully protected from chemical splash hazard.

The possibility still exists. Because of this reason, you need to make sure that an eyewash station is available in the laboratory.

Chemical Spill Kits

Chemical spill kits are required for handling hazardous chemical spills in the laboratory. The key is to provide the kits in enough quantity and place them on the appropriate location.

First Aid Kits

Make sure that the first aid kits is available in the laboratory and the content is complete. Inspect regularly the content and immediately add first aid kits item if already used up.

Personal Protective Equipment

You must provide all basic personal protective equipment for every lab analyst; lab coat, apron, eye goggles, nitrile gloves, and face shield.
