Amoeba Cell Characteristics, Structure, Movement, Nutrition, Reproduction, Disease, Habitat.
Amoebae are essential components of aquatic and terrestrial ecosystems and play a vital role in the dynamics of microbial communities, nutrient cycling, and energy flow (7, 8).They are also a potential threat to human health, as some of them are pathogenic or even lethal to humans (7, 9, 10).There are several excellent reviews on amoebae and their bacterial symbionts (11,- 15).

An amoeba is an aquatic, single-celled protist characterized by a gelatinous body, amorphous shape, and amoeboid movement. Amoebas can form temporary extensions of their cytoplasm known as pseudopodia or "false feet" which can be used for locomotion or capturing food. Food acquisition is amoebas occurs by a type of endocytosis called phagocytosis.

The structure of amoeba consists of an ectoplasm and endoplasm. Various organelles like the nucleus, chromatin granules, and food vacuoles are present in amoeba's structure. Culture Preparation of Amoeba Cell To grow and study amoeba cells in a lab setting, adequate culture preparation is essential.

Structure of amoeba primarily encompasses 3 parts - the cytoplasm, plasma membrane and the nucleus. The cytoplasm can be differentiated into 2 layers - the outer ectoplasm and the inner endoplasm The plasma membrane is a very thin, double-layered membrane composed of protein and lipid molecules.

Abstract. Amoeba proteus contains a central elongated fluid portion (plasmasol), a rigid layer surrounding this (plasmagel), a thin elastic surface layer (plasmalemma), and a hyaline layer between the plasmagel and the plasmalemma which is fluid at the tip of active pseudopods and in certain other regions. The plasmasol is an emulsion.

The amoeba possesses no mouth or anus. They feed by surrounding their cytoplasmic extensions around the food particle and then forming a vacuole. Enzymes are then secreted to digest the food particles. The contractile vacuole functions to remove excess water from the amoeba and thus maintain the osmotic pressure of the organism.

Structurally, amoebas closely resemble the cells of higher organisms. "They are like our cells, and in fact, when they are moving they look very much like our white blood cells," Maciver said.

This movement strategy produces forward movement via the following three steps: "ballooning" the plasma membrane forward. This distinct rearrangement is known as a pseudopodium or "false foot", which is very similar in nature to that of the lamellipodium generated in higher vertebrates;

1. Cell membrane: Also called plasmalemma, it is a thin-layered membrane composed of protein and lipid molecules that restricts the entry and exit of substances in and out of the cell. 2. Cytoplasm: A mass of a jelly-like substance that holds all the other organelles. It consists of two parts:

Pseudopods or Amoebas' false feet. A pseudopod is a temporary arm-like projection that is developed in the direction of movement. When the Amoeba stretches its pseudopods, the cytoskeletons (like the cells' skeleton system) inside the cell rearrange and extrude the cell membrane to change the cell shape. Once the tips of pseudopods adhere to the substrate, the cytoplasm of the cell flow to.
Who discovered Amoeba?
Bacteria, plant cells, metazoa, algae, protozoa are some of the common examples of what an amoeba eats. Yet, it does not have a well-defined mouth or anus for secretion or excretion. Since every amoeboid cell is a pseudopod, it does not have a definite shape. However, the size of an amoeba cell is around 250 and 750 microns.
