Amoebas


An amoeba, sometimes written as "ameba", is a term generally used to describe a single celled eukaryotic organism that has no definate shape and that moves by means of pseudopodia. Pseudopodia or pseudopods are temporary projections of the cell and the word literally means "false feet". The cell uses the pseudopodia as a means of locomotion. The plural of amoeba is "amoebae", not "amoebas". Although the word "amoeba" or "amoeboid" is often used to refer to all protozoa that move using pseudopodia, the word Amoeba (written in italics and with a capital letter) refers to a specific genus of protozoa of which Amoeba proteus is the best-know species.
The cytoplasm of an amoeba contains the organelles and is enclosed by a cell membrane. An amoeba uses a process called phagoctyosis to obtain food. This is a process in which projections of the cell membrane of the amoeba extend and surround the food particle, totally enclosing it. The food particle is thus internalized in a sort of "bubble" called a vacuole. The food particle can then be digested in the vacuole. The amoeba reproduces via mitosis.

Some amoebae can cause disease. For example Acanthamoeba can cause amoebic keratitis and encephalitis in humans.

Amoebae, viruses and bacteria are microorganisms. The study of microorganisms is called microbiology.

The answer is Volvox
Volvox are protists that live in colonies, or groups of organisms living together. They are both autotrophs and heterotrophs. They use their eyespot to detect light when they undergo photosynthesis. They also have tails, or flagella, they use to move the colony.

ANSWER IS VOLVOX

As a colony:

Example of single celled organism that exists as a colony is Volvox. In biology, a colony refers to a number of individual organisms of similar species existing together for mutual benefit.

Examples of such benefits they could get from each other include the strength or the ability to attack a bigger prey. Some insects like ants and bees live in colonies.

Colonial organisms are organisms that live intimately together, in a colony. For instance bacteria, Volvox, Pandorina, Sponges, algae and Salps are also examples of colonial organisms. Each organism/cell in the colony can exist on its own and may or may not benefit from other cells in the colony.

In biology, a colony refers to individual organisms of the same species living closely together, more often than not for mutual benefit, like stronger defense or the capacity to assault bigger prey. A few insects like ants and honey bees live only in colonies.

A colony of single-cell organisms is referred to as a colonial organism. Colonial organisms were almost certainly the first step toward multicellular organisms through natural selection.

A bacterial colony is defined as a observable cluster of bacteria that grows on the surface of or within a solid medium, most probably cultured from a single cell.

Due to the fact that every organism inside the colony descends from a single antecedent, they are genetically the same apart from mutations that usually take place at a small frequency, in addition to a possibility for them to be contaminated.

Getting hold of that type of genetically matching organisms or pure strains can be useful in loads of cases. It can be done by dispersing bacteria on a culture plate and starting a fresh stock of bacteria from a single colony.

A biofilm is a colony of microorganisms over and over again made up of a lot of species, with properties and abilities greater than the combinations of abilities of the individual organisms.

Types of cell colonies

In the process of evolution unicellular organisms began to co-exist in three different ways:

1. A colony is a group of related living organisms that are linked to each other through their own secretions, or cytoplasmic strands, but there isn’t any suitable transportation system between the cells.

Colonies are formed due to daughter cells that stay together instead of separating apart from each other after the cell division. Any member of the colony has the capability to exist on its own.

2. Symbiosis is an inter-relationship between two or more different organisms which usually benefit from the relationship.

3. Endosymbiosis is a form of symbiosis where a colony member known as a microsymbiote lives within the other. Nowadays, scientists are of the opinion that the cell organelles mitochondria are, in reality, microsymbiotres that formally lived as free living bacteria cells. Ultimately these bacteria developed into a part, or organelle, of the host cell. This type of relationship is referred to as endosymbiotic.
