hi everyone welcome to wedra studio today we are going to talk about parium so now let's get straight to it parium is a single cell protozoan that belongs to the Kingdom Protista it was first discovered by Anton vanley wiik the father of microbiology as early as 1674 the name comes from the Greek word paramix which describes the cells oblong oval shape parium has a stiff outer cover that gives it a slipper-like appearance parami do not have vital organs such as the brain heart eyes kidneys and ears their lengths range from 50 to 350 micrometer which
is 6,000 times smaller than a PA parium are present naturally in most water habitats such as freshwater ponds and rivers they can also be found in areas of high salinity for example permium kiny that can live in Tidal brine pools near the sea as a part of ciliates parium are covered in cyia which are short hairlike structures they are wonderful swimmers and can move forward at rates up to four times their own length per second paraman consume bacteria algae and yeast as food they are able to detect bacteria and other prey by sensing certain Chemical
indicators like folic acid and other metabolites of the cell by the help of cyia parium sweeped the food into the oval Groove and then digested within the cell in the food vacul through a process called fagocitosis predators of parami include amoeba didinium and water fleas they use spiky tresy for defense and perform avoidance reactions quickly in which the cyia beat to swim backward parium have anal pore two contract vacul that regulate the water content of the cell and two nuclei a large macronucleus and at least one small micronucleus the macronucleus is the center of all
metabolic activities and regulate most cell functions while the micronucleus is involved in the reproduction when abundant nutrients are available with appropriate conditions permium reproduce asexually by binary fishing in which a fully grown organism divides into two daughter cells some species can undergo binary fishing so many times before they lose their Vitality whereas species like parmesian tetelia is only able to undergo fishing 200 times before expiring sexual reproduction by conjugation takes place under conditions of starvation it involves the temporary Union of two genetically compatible organisms and the exchange of micronuclear elements under conditions of prolonged starvation
parium can undergo autogame or self- fertilization it is the same as conjugation but it is only happening with a single cell did you know that parami are able to learn despite having no nervous system studies show that cell memory may be possible they can be taught to differentiate different levels of brightness spe species like parium cotum are able to communicate through glass barrier It is believed that they use a form of weak electromagnetic radiation biop photons to communicate also parium is useful to monitor water quality researchers noticed that their swimming speeds declined when pollutants such
as heavy metal zinc chloride and copper sulfate were present in the sample there are species like parium Orelia which contain Kappa particles that can kill other strains of parium the killer tra is caused by the particles which are the symbiotic bacteria the earliest fossil discovered of parium dated back at least 65 million years ago they could be the oldest creatures on Earth emerging nearly 4 billion years ago well that's all for today and thanks for watching if you like our video please click the like And subscribe button below we'll see you in the next video
