Ameba is eukaryotic in a simple form. It is one of the organisms that travel in a unique characteristic. It crawls to move its body from somewhere to another place. But, it shows that this type of organism doesn’t have a close relationship to other types of ameba if we compare between them.
The structure of the cell
There are two groups in all types of living organisms. Those two groups are including eukaryotes and prokaryotes. They are different from one to another. The way we differentiate them is by the complicatedness of the cells they have. The cells in prokaryotic are less organized compared to the cells in eukaryotic. Eukaryotic has very organized cells inside of it. The examples of prokaryotes are Archaea and Bacteria. Meanwhile, the other types of living organism that are not mentioned belong to eukaryotic including ameba and it will explain what structure contains the amebas DNA.
Ameba is including eukaryotes. The shape of its body commonly is in a single form of a cell. The ameba’s cells have specific features from other types of organism. Their content of the cellular and the cytoplasm are very close to a membrane’s cell. And then its DNA is covered in the main compartment of cellular that is known as a nucleus. Last but not least, this nucleus has unique structures that are known as organelles. So, the question of what structure contains the amebas DNA has the clear answer now. It is in ameba’s nucleus.
What are organelles? The main function of organelles is to carry out the function of the cellular including protein transport and energy production. A lot of organelles can be found in every eukaryotic cell. But, there are few cases that do not apply this fact.
The first example is the Entamoeba histolytica. It is a type of parasite that can give effect yo dysentery of amoebic in our body. It doesn’t contain the apparatus of Golgi. The responsibilities of organelle are two things. First, it modifies proteins and the second it transports the protein. There is a study in 2005 which shows that Entamoeba histolytica has vesicles or compartments which its form looks like a Golgi and has the same responsibility. This study is called “The Journal of Biological Chemistry”.
According to some experts, ameba also doesn’t contain mitochondria. Mitochondria have a task to produce energy of the cellular. It happens because they live in a condition full of anoxic. Based on a journal published in 2014, it stated that organism like mitosomes and hydrogenosomes which have organelles have a connection to mitochondria. And those types of an organism commonly have a maximum change of the same versions. This condition also happens in an amoeba-like Mastigamoeba Balamuthi which has a free-living and also Entamoeba histolytica.
Talking about what structure contains the Amebas DNA which is already answered, the amoeba has same resembles of greater organisms’ cells. Some of the scientists even say that the way blood cells move is similar to amoebae. They both move in the same way. Pseudopodia in amoebae are familiar to be called as wrong feet. Like in the white blood cells, amoeba travels from one place to another place using those wrong feet. The outside projections of the short-lived cytoplasm can make ameba propel itself to move forward and grip a surface easier.
Several studies show that pseudopodium travels in a direction including when it moves to reach the surface. While it travels in one direction, there is its part of the body which contracts. It is its back end. There are two things that happen when the back end of ameba contracts. The first thing is that the contraction makes the adhesions in ameba to be pulled up at the cell’s back end. Meanwhile, the contraction also gives effect to the cytoplasm at it is able to move forward. When it moves forward, the contraction helps the pseudopod to be filled when it expands.
The way we describe the adhesion exists between the surface and ameba that it moves is called as an adhesion of physical molecular. These adhesions that are broken at the back and forms constantly at the front end. And this kind of movement differentiates these types of amoeba from other types of protists since protists do not move using pseudopodia. But, what are protists? It is simple eukaryotic organisms that are not fungi, animals, or plants like an amoeba.
The different types of pseudopodia
Now, let’s talk about the various types of pseudopodia based on what they look like compare to ameba. Based on several studies, the appearance of Labour Psedupodia’s projections of cytoplasmic is blunt and broad. Meanwhile, the appearances of Filopodia or Filose Pseudopodia’s projections are thin and a little bit thread-like. What about other pseudopods? Well, their structural elements are supported by microtubules. These microtubules’ function is to execute the movements of the cells.
In the projections of Reticulopodia, they are thin and the structure is almost the same as filament which meshes between one another. Last but not least, Axopodia or Actinopodia are formed by microtubules’ core. They are rigid and there is cytoplasm around it.
The way ameba eats
Besides ameba uses its pseudopodia to travel between places, it is also used to feed. Phagocytosis is a process of digesting material that is solid. What is its food? Well, most of the amoebae eat bacteria since they have receptors to bind their prey. These receptors can be found on the surface of their cells. After the ameba is successfully targeting and binding the bacteria to be eaten, it will be taken into the phagocytosis that is commonly at the cells’ corner.
Amoeba Proteus as the giant amoeba has a little bit different. This type of giant ameba mostly engulfs their food by collecting the pseudopods. When the prey is successfully drawn, the membrane of the cells around it will crush it in a compartment that has intra-cellular form.
That’s pretty much everything related to what structure contains the amebas DNA and other information about this micro creature. So, the nucleus is the part where DNA of ameba can be found.
