Sarcodina, Amoeboid locomotion Asexually reproduction is through binary fission or The Protozoa Intestinal Protozoa -The Amoebae Endolimax nana Occurrence - occurs in about 14% of the US population; 21% worldwide. Nutrition 6. on dead or decaying organic matter). They contain a central axial rod which is A flagellum pushes the fluid medium at right angles to the surface of its attachment, by its bending movement. Locomotion. Spiral movement in anti clockwise direction. Appearance of cytoplasm - smooth & clean or vacuolated. Asexual reproduction by binary fission and sexual Association with pinworm - the organism may be transmitted from host to host within the egg of Enterobius vermicularis. (Some non-ciliates, such as those of group Opalinata, possess cilia-like . Thus, With these, they can creep over the substratum.III. Example: Globigerina. Few flagella are present in each cell, generally \(1\) to \(4\). Amoeboid movement performed by pseudopodia and Dr Shifa Ul Haq. ZOO 101: ANIMAL DIVERSITY I Costa - a thin, firm rod-like structure running along the base of the undulating membrane. This type of locomotion is seen in Amoeba, etc. Cyst - the inactive, non-motile, infective stage; survives the environment due to the presence of a cyst wall. Locomotion by pseudopodia is seen in Amoeba, flagella in Euglena, and cilia in Paramecium. 1. that either push or pull. Most infections are asymptomatic; chronic cases experience weight loss, malabsorption of fat, protein, folic acid, and fat-soluble vitamins. The Protozoa . apicomplexa. 2. 7) Nuclei of protists contain multiple DNA strands. Phylum Protozoa: Methods of Locomotion, Amoeboid, Metabolic, swimming Contains nucleolus or nucleoli (rRNA synthesized) or Actinopodea Recovery stroke- During recovery stroke, the flagellum becomes comparatively soft and will be less resistant to the water. Spores absent. Flagellar Movement 3. Understanding protozoa locomotory organelles and locomotion methods is important for several reasons. and recycle organic material) and water molds (thrive Pseudopodia
