Paramecium ingestion and digestion process

  1. Aug 16, 2015 #1
    The structure of the Paramecium is rather complicated. Its plasma membrane is specially equipped with thickenings, so the membrane can be strengthened. Then, this membrane is called the pellicle.

    A paramecium has one big nucleus and two smaller nuclei. The bigger nucleus is about nutrition, and the smaller nuclei are for reproduction.

    There is a definite location on the pellicle for the input of food. It is called the mouth. Inside the mouth is a canal called the cytopharynx. The cilia around the cytopharynx are longer. When there is food, these cilia swipt to form a swirl of water, then, the food particle can be carried into the cytopharynx. At the end of the cytopharynx, food vacuole can be formed. This is the ingestion method of paramecium.
    The food vacuole would travel along a definite route in cytoplasm. At the end of the journey, the vacuole would endock at a definite point on its pellicle and decantes the waste from the vacuole. This point is called the cytoproct.


    I have found this information from a site,don't know whether it is reliable.Just for confirmation and verification Are all these correct?

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    As has been said in favour of the historical truth of the Gospels, it doesn't sound like the sort of story anyone would make up for fun.
    And I do remember reading a good bit of what you quote in a school textbook decades ago.

    Paramecium belongs to a Kingdom, the Protists, which tended to fall out of mainstream fashion amongst biologists for decades, so on a site like this year could possibly not find in a week anyone who knows much about them, but are possibly coming back. They possibly contain more fundamental diversity than all other organisms put together. They have even at molecular level mechanisms that are exceptions to rules foud to hold right across animals, plants and bacteria. Important for some difficult human and animal pathologies, in primis malaria.

    Quite a universe for people coming along now to explore in future. You never can tell. :oldsmile:
