According to Biology Resources, the amoeba does not have a cell wall. Amoebas are single-celled organisms called protozoans.Know More
The structure of the amoeba is that of the protozoan. They are microscopic organisms. The type of amoeba studied in labs is the amoeba proteus, which is only 0.3 mm in diameter.
The creature is made up of only a single cell, and it has only a nucleus and cytoplasm. The amoeba has no chlorophyll or cell walls, so it takes in and digests solid food. It's possible to find these creatures in ditches, ponds, soil and moist locations.
The outer layer of the amoeba's cytoplasm is called an ectoplasm. It is a clear gel. The rest of the creature is primarily made up of endoplasm, which is more like a fluid that contains minute structures and granules. Uniquely, an amoeba does not have a typical shape and changes all the time; it changes particularly often when needing to move or feed.
Surprisingly, amoebas do not have flagella or cilia to help them move. They instead move by flowing the cytoplasm over mud, soil or other surfaces. When they need to eat, amoebas surround the microscopic plant or food source with pseudopodia. The food is then digested with enzymes produced by the amoebas.Learn more about Zoology
Since their discovery, in 1757, amoebas have been found living in almost every imaginable aquatic habitat. They are endemic in fresh water, salt water, rivers, creeks and streams. Some amoebas can be found in morning dew, while others are parasitic and live in the bodies of other organisms.Full Answer >
Amoebas belong to the domain eukarya, the kingdom protist, the phyllum protozoa, the class rhizopoda, the order amoebida and the family amoebidae. This is the scientific classification of the genus amoeba, which includes many species of amoeba.Full Answer >
The finger-like extensions of the amoeba are called pseudopodia. The word "pseudopodia" means false feet, and they help the amoeba move forward and to ingest food.Full Answer >
An amoeba belongs to the kingdom called Protista. Its species is Amoeba proteus. Amoebas are unicellular organisms found mainly at the bottom of water bodies and near decaying vegetation. However, amoebas also exist inside the digestive tracts of some animals and humans.Full Answer >
