How does the Paramecium regulate its water content? The Paramecium regulates its water content through their contractile vacuoles which excrete excess water. The excess water is collected into a contractile vacuole which swells and finally expels water through an opening in the cell membrane. Q 7. How does the Paramecium ingest food particles? Describe the process from detection to ingestion. The Paramecium ingests food particles through its cilia which sweeps

Paramecium are ciliate protozoan‚ the whole body is covered with cilia‚ which help the organisms to swim forward‚ backward and turn (Kimbal‚ 2003). They are shaped like prolate spheroids of 250mm length. It generally feed on bacteria‚ other small cells‚ yeast or small alga (Roberts‚ et. al. 2003). According to Guiffre‚ et. al.

Our hypothesis are that we will discover an bacillus‚ coccus‚ or a spiral shaped bacteria. Paramecium caudatum/ Bacteria Species of Paramecium can be distinguished from other ciliates by their cigar or slipper shape and the undulating membrane within the peristome - a furrow that leads to the cytostome‚ where food vacuoles are formed.

1. Living organisms play an important role in the recycling of many elements within an ecosystem. One such way this idea can be proven is through the study of carbon in an ecosystem. Plants‚ for starters‚ are a major part of this carbon cycle. During photosynthesis‚ plants remove carbon dioxide from the atmosphere and release oxygen as a waste product. Another major contributor to this vital cycle is the human being. The average human being goes through respiration each day to help maintain

After viewing the protists‚ the group used alcohol to kill all the protists so that they would not be infected by them. They also saw firsthand what alcohol does to them. The group had fun because they got to see the Paramecium and Balantidium coli moving around really fast. Because of this experiment‚ the

Differentiating Between Prokaryotic and Eukaryotic Cells‚ Distinguish Among Plant‚ Animal‚ and Protist Cells‚ and Identifying the Organelles that are Evident in Them Introduction There are two different types of cells‚ prokaryotes and eukaryotes. Prokaryotes‚ such as bacteria‚ lack a nuclear membrane and other membrane bound organelles. Their genetic material consists of a single molecule of singular DNA. Eukaryotes‚ such as plant and animal cells‚ have a nuclear membrane and other membrane
