This video will help you to learn What is an Amoeba? with Example.
What is an Amoeba?
Have you ever observed microscopic Amobea in your biology lab?
If not “don't worry”.
In this video, we will learn about Amoeba
Amoeba is a genus that belongs to protozoa, which are unicellular eukaryote with membrane-bound cell organelles.
August Johann Rosel von Rosenhof was the first to discover Amoeba in 1757.
The name Amoeba is derived from the Greek word amoibe, which means change.
There are many species, of which the most extensively studied is Amoeba proteus.
Amoeba is found in terrestrial as well as aquatic habitats.
However, some are parasitic in nature, thereby causing harm to humans and animals.
For Example - Entamoeba histolytica that causes amoebiasis.
Lets learn about the structure of amoeba.
The cell of an amoeba consists of a cell membrane, a nucleus with genetic material, food vacuole for digestion of food, and a contractile vacuole for osmoregulation.
An Amoeba can have more than two nuclei in a cell. Similar to other protozoans, it reproduces asexually either by mitosis or cytokinesis.
During the forceful division of Amoeba, the portion that contains the nucleus survives, While the portions without nucleus die.
On the other hand, when Amoeba is exposed to the lethal environment, it turns into a dormant form, known as the Amoebic cyst.
It continues to remain in the cyst form until it encounters favorable environmental conditions.
Besides this Amoeba possesses pseudopodia for locomotion and feeding purposes.
The pseudopods are extensions of the cytoplasm.
Let’s move on to the nutrition in Amoeba.
Amoeba has a holozoic mode of nutrition.
The food sources of Amoeba are usually bacteria and other protists. While some are detritivores and eat dead organic material.
They ingest their food by phagocytosis, in which they spread their pseudopods around food particles and engulf it.
After ingestion, food is transferred to the food vacuole where it is digested by enzymes.
Digestion in amoeba is intracellular that is taking place within the cell.
After digestion food vacuoles are transported deeper into the cells by cytoplasmic movements and undigested waste is expelled out through the cell membrane.
This concludes our video on “Amoeba”.

Thank you! How can you measure surface area of an amoeba?
Interesting mathematical integration question
is it smaller than a virus
You already mentioned that the name of the inventor at the beginning of video .. thanks a million for the info.

Could you help me out with this my first time listening to this
I am Rudimentary in this area lol
@@aronchenevert5062i'm going through the same thing rn lol
Great work 👍
How can we find? ur all biology videos
i am so very happy each of these question i asked to myself was abslutely correct😊. and i understood it , it is so easy.
It's is the most important in boi it's know to the reproduction in plants, animal, human
amazing
Nice video sir
Thanku sir 😍😍🙂
Good 👍🏻👍🏻
Thanks tomorrow is my exam nice explain
An amobea moves by? (...) what is the answer please :)
Pseudopodia
Hey this is not e.histolytical because it has less than 4 nuclei but there are more than 4 nuclei
Are they like macrophage
Hi
Really it's gd
Thanks
these is better than vedantu
Thanks
I deployed to Iraq with a transport company, the guys we relieved in country would “surf” on the lead vic’s mine-roller.
Nice video 😊

Am i hearing it right the cellophane amoeba?
I am from podar learn school
I got an attack of amoeba attack when I was 9 I don't what was that before I survived somehow it was a very difficult video I got that by eating a pizza

Jesus is coming back very very soon please repent and turn to Him because He loves you and He will accept you. Let the Bible be your daily guide
For arfa teacher is not going to work
Ok
The English language is getting a little garbled here. "One amoeba / two or more amoebae" (pron. a_ME-bee). "free-living or parasitic, single celled, Kingdom: Protista, Phylum: Rhizopoda, many families and genera.
Thank you
Thanks
