What are the defining features of diplomonads?

Diplomonads are small cells, usually around 10 μm in length and often less. With the exception of the enteromonad organisms (see ‘Systematics’), diplomonads have a characteristic ‘doubled’ organization. Each cell has two identical-sized nuclei located alongside each other in the anterior half of the cell (Figure 4).

Why do diplomonads have 2 nuclei?

Most diplomonads are double cells: they have two nuclei, each with four associated flagella, arranged symmetrically about the body’s main axis. Like the retortamonads, they lack both mitochondria and Golgi apparatuses….

How do diplomonads reproduce?

duodenalis is generally considered to replicate only asexually, by simple binary fission, evidence suggests that genetic exchange does occur, although the mechanism of sexual reproduction remains unresolved, and the significance of sexual reproduction to the pathogenicity and epidemiology of Giardia is also unknown.

How many flagella do diplomonads have?

eight
Diplomonads are characterized by eight motile flagella organized into four bilaterally symmetric pairs. Each of the eight Giardia axonemes has a long cytoplasmic region that extends from the centrally located basal body before exiting the cell body as a membrane-bound flagellum.

Is there such a thing as a diplomonad?

Also found in: Encyclopedia, Wikipedia. diplomonad a member of the group at one time considered to be an order of the Protozoan class Zoomastigophora but more recently considered to be of kingdom-equivalent status. The group contains both free-living and parasitic forms. see CLASSIFICATION.

How do you define’family’in the New York Times?

The definition of family to me is a group of people who truly love each other and care for you. But yes the circumstances of what family use to be is now changing into new categories of families. Family life is changing but so are people.

How big is the nucleus of a diplomonad?

Diplomonads are small cells, usually around 10 μm in length and often less. With the exception of the enteromonad organisms (see ‘ Systematics ’), diplomonads have a characteristic ‘doubled’ organization. Each cell has two identical-sized nuclei located alongside each other in the anterior half of the cell ( Figure 4 ).

How are diplomonads similar to the retortamonads?

They are placed among the metamonads, and appear to be particularly close relatives of the retortamonads . Most diplomonads are double cells: they have two nuclei, each with four associated flagella, arranged symmetrically about the body’s main axis. Like the retortamonads, they lack both mitochondria and Golgi apparatuses.
