4 -- Part 1: Functional Anatomy of Prokaryotic and
Sophia is an 8-year-old child who has just been diagnosed with a urinary tract infection.
You told Sophia's mother that children and girls are more likely to suffer from utis.
Sophia was given penicillin last winter to treat a chest infection, but her mother asks why she can't have it again.
The cell wall can be found on pages 80-85.
There are answers to In the Clinic found online.
All living cells can be classified into two groups based on their structural and functional characteristics.
Eukaryotes are larger and simpler than prokaryotes.
The DNA of prokaryotes is usually a single, circularly arranged chromosome and is not surrounded by a membrane; the DNA of eukaryotes is found in multiple chromosomes in a nucleus.
There are specialized structures that carry on various activities in prokaryotes.
Plants and animals are made of cells.
Prokaryotes includebacteria and archaea.
The organisms that are cellular are called eukaryotes.
There is a sticky glycocalyx surrounding prokaryotic and eukaryotic cells.
Mostbacteria are stuck to solid surfaces, not free-floating.
The cells are held in place by the glue of the glycocalyx.
In the Clinical Case, there is an example of a problem with hospital water supplies.
The cell structure of prokaryotes and eukaryotes can be compared.
Their cell walls are easy to understand.
In cell division, there is usually a combination of sugars and Lipids.
They use the same kinds of chemical somes replicate and an identical set is distributed into each reaction.
Normally, a singular, circularly arranged chromosome is what their DNA is.
They do not have histones associated with their genes.
They don't have any organelles.
Prokaryotes are recovering from rotator cuff surgery.
The complex poly breathe on her own.
Most of the time, the majority arebacteria.
Pick out the three basic shapes ofbacteria.
99% of thebacteria in nature exist in biofilms and most are 0.2 to 2.0mm in diameter.
The bacilli look like straws.
There are two meanings to "Bacillus".
bacillus refers to a shape of a bacterium.
Capital Streptococci refers to a specific group.
bacteria are never straight and have one or more twists.
There is a division in one plane.
Cocci can be either round or flat on one side.
Cells can remain attached to one another when cocci divide.
In the top multiple planes and form grapelike clusters or broad sheets are micrograph, a few joined pairs of bacilli could serve as examples of diplobacilli.
Group characteristics can be used to identify certain cocci.
A bacterium's shape is determined by its genes.
A number of environmental conditions can change that shape.
Identification becomes difficult if the shape is changed.
We will discuss structures outside of the cell wall, the cell wall itself, and structures inside of the cell wall.
The chemical composition varies with the species.
The wall is made up of the glycocalyx, flagella, fimbriae, and pili.
There is a substance called Figure 3.14a on the surface of prokaryotes.
The bacterium sectioned length appears split in the wise to reveal its internal composition.
The thinness of the "slice" only structures labeled in red does not convey the allbacteria.
The prokaryotic cell shows structures that may be found inbacteria.
Prokaryotic cells don't usually have the same structure as other cells.
The cytoplasm, ribosomes, and a nucleoid are found in allbacteria.
