There are many similarities between amoeba and paramecium; however, there are also some notable differences between them. Reproduction in amoeba chiefly occurs by asexual method, i.e., by binary fission, multiple fission and sporulation. Pseudopodia are temporary finger like projections with blunt rounded tips which are constantly being given out or withdrawn by the body. This membrane is selectively permeable and regulates exchange of water, oxygen and carbon dioxide between the animal and the surrounding medium. The main components of an amoeba’s diet are bacteria and algae. The division involves nuclear division (karyokinesis) followed by division of cytoplasm (cytokinesis). Main Difference – Amoeba vs Paramecium. It is the lifeblood of the amoeba. 26 June 2017. Their common form of prey is bacteria. flagellum. The old macronucleus disintegrates and a new one is formed. Paramecium swim place to place in the search of food. “Paramecium.” Encyclopædia Britannica. The pellicle gives the paramecium a definite shape but it is flexible enough to allow small shape changes. This process is usually followed by asexual reproduction. Both amoeba and paramecium reproduce asexually by binary fission in favorable conditions. Available here. The food goes through the cell mouth into the gullet. Spores are formed in dry conditions and during insufficiency of food and those spores are germinated under favorable conditions. Paramecium is one of the simplest organisms on our planet, and studied extensively to understand the way other organisms might function. The ingested food is digested inside a vacuole and the wastes are eliminated through the anal pore. It starts with the breakdown of nuclear membrane and release of chromatin blocks into the cytoplasm. After nuclear division, the cell membrane divides into two parts by constriction and along with this the cytoplasm also divides due to which two offsprings are produced from the parent amoeba which develops individually. Paramecium: Paramecium moves by beating the cilia. Encyclopædia Britannica, inc., 12 June 2015. Paramecium is a unicellular, microscopic, free-living organisms. Nucleus is the major organelle of the amoeba, located centrally; it controls reproduction (it contains the chromosomes) and many other important functions (including eating and growth). Cilia – hair like appendages that help the paramecium move food into the oral groove and also responsible for locomotion (movement) The paramecium moves by spiraling through the water on an invisible axis. Nucleus – The nucleus has a firm nuclear membrane or nuclear envelope and contains a clear achromatic substance with minute chromatin granules or chromidia distributed uniformly near the surface. ⬇ Download amoeba diagram in color - stock pictures and pictures in the best photography agency reasonable prices millions of high quality and royalty-free stock photos and images.
