Prokaryotes vs. Eukaryotes: The Wonders of Each
Transcript of Prokaryotes vs. Eukaryotes: The Wonders of Each
The Prokaryotic Cell
Prokaryotes are extremely well known for their absence of a "true" nucleus, in which they posses organelles that are not all found in eukaryotic cells, making them distinct and unique. Prokaryotic cells are found in only bacteria, in which they are often of small size, ranging from 1-10 um in diameter.
Organelle #1: Pili
Pili are attachment structures found on the surface of the cell. They aid in providing mobility for the bacteria, and even function in the process of transmitting genetic material. They exist in a large quantity per cell, and can be viewed (on the left) as the only structures outside the cell that appear as spikes.
Organelle #2: Nucleoid
Although the prokaryotic cell lacks a membrane-enclosed nucleus, it does contain a nucleoid. This organelle is where the cell's DNA is located at. In the picture at the left, the nucleoid can be identified as the light gray area in the middle of the cell.
Organelle #3: Ribosomes
Ribosomes are present in all prokaryotes, in which they are responsible for the protein synthesis that occurs inside the cell. Some refer to these organelles as the protein factories of the cell, since they manufacture proteins that aid the cell, overall, in carrying out its natural processes.
Organelle #4: Plasma Membrane
The plasma membrane in prokaryotic cells maintains a rather simple job, although it is easier said than done. It is responsible for enclosing the cytoplasm and keeping it in the cell.
Organelle #5: The Cell Wall
The cell wall is a rigid structure that is located outside the plasma membrane, in which it serves as a form of protection for the cell.
Organelle #6: The Capsule
The capsule is a jelly-like outer coating of many prokaryotes. It's role in the cell is to serve as what is known to be a virulence factor. This means that the capsule enhances the ability of bacteria to give diseases.
Organelle #7: Flagellum
Flagella are string-like locomotion organelles that are located on the rear ends of some bacteria. They aid in providing motility for the prokaryotes, in which it all sums up to giving the cell a mobile perspective and ability.
Animal Eukaryotic Cells
well what is this animal?
this is a rihno or what is left of it
this animal is
(or was because it is dead)
made up of billions of cells that are working to make him or her possible to be alive!
well as you can see the animal cell is madeup of orgallnes. each one has a specific job or niche.
Well here we have
of the cell organlles but some are only found in animal cells like
centrioles (microtubes that are in pairs but fuction is unknow at the moment that are only found in animal cells), and the flagella (the tail of the animal cell that helps with movent of the animal).
Now the name of the other organells
nucleus( note the cell nucleus has 3 diffrent layers).
#3 & #5
is the lysosomes
golgi X (X because it has diffrent names but im goin to referenc it as
mitochondrion just to name a few.
This video may help!
this is just a look at both plant cell and a animal cell at the same time and they both have alot in comen. so to get a general idea of the animal and a plant cell.
