This was a large multi-function room capable of seating the bulk of the population of the house. The family would sit at the head table on a raised dais, with the rest of the population arrayed in order of diminishing rank away from them. Tables in the great hall would tend to be long trestle tables with benches.
Protozoan Cyst is a defense mechanism in the Protozoan family. It takes this form according to the conditions of the host. A change in pH, a change in oxygen supplies, anything that trigers the genetic mechanism. The cyst is evacuated trough the sediment. You could say that Cyst are a defense mechanism.
Protozoa, from the Greek meaning âfirst animalâ, refers to simple, eukaryotic organisms composed of a microscopic single cell. Reproduction is through simple asexual cell division, or binary fission, in which two daughter cells are formed or, if many daughter cells are formed, multiple fission.moebae: These are the simplest of the protozoa and are characterised by a feeding and dividing trophozoite stage that moves by temporary extensions of the cell called pseudopodia (âfalse feetâ). In some species the trophozoite can form a resistant cyst stage able to survive in the environment.
