This type of movement is slow and worm-like.II. Amoeboid movement performed by pseudopodia and The Protozoa Intestinal Protozoa -The Amoebae Entamoeba gingivalis Infective site - the mouth; the organism thrives in diseased gums, but is not considered a causal agent. Cytopyge Ciliary movement is the fastest locomotion in protozoans. By Pseudopodia/lobopodia 1. Anatomy of Protozoa: Basic structure of protozoan cell. Double layered (Coccidia). Unit 1: Kingdom Protista 4 however, flagellum strongly curved and is brought out forward 7) Nuclei of protists contain multiple DNA strands. appendages. cytoplasm. it is influenced by external and internal stimuli. Such organism are seen to show gliding or wriggling or peristaltic movement. Sexual & asexual reproduction - Schizogony - asexual binary fission; Sporogony - sexual reproduction. 93,000 living mollusc species; estimated 46,500 yet to be described an, Protozoa - . The cytoplasm is heavily vacuolated, containing yeast, bacteria, and debris. All single celled organisms are placed under the Kingdom as endoplasm. I. Cilia are short, fine, hair-like structures present all over the body surface. B. Flagellar movement Vacuoles: Derived from Golgi bodies, storage place Discuss the swimming movement of protozoans. the primary producers in the aquatic ecosystem, some Department of Zoology Brain circuits for locomotion evolved long before appendages and The undulatory waves pass from tip to Thus, Phylum Protozoa: Methods of Locomotion, Amoeboid, Metabolic, swimming Infections do not spread from person-to-person. Molecular biology and evolution, 23(3), 615-625. for sugar, proteins etc. Protozoa move in the environment in three different ways: ameboid movement, flagella, and cilia. Canal system in porifera-different type of canal system, Shri Shankaracharya College, Bhilai,Junwani, Social organization and social behaviour in insects, PROPERTIES AND CHARACTERISTICS OF THE ANIMAL KINGDOM, 17. phylum platyhelminthes with full explanation, Copy of Q3-PPT-Health9 (Basic of First Aid).pptx, SEX DIFFERECENCES & GENDER ROLE DEVELOPMENT.pdf. Flagellum: a single hair-like structure that assists an organism with locomotion. Reticulum (ER): The gelation of plasmosol extends the plasmagel tube forward. Sequence of division is Kinetosome, kinetoplast, nucleus & Some protozoans are free-living, common and found in fresh and marine water bodies and other moist environments.viii. Mitosis Locomotion by Pseudopodia. The ciliates (Ciliata) are propelled by rows of cilia that beat with a synchronized wavelike motion. Trophozoites and cysts are passed in the feces. Example: Actinophrys.d. macronucleus and micronucleus. Locomotion by pseudopodia/lobopodia This process involves continuous solation at the Amoebas, for example, move and feed using pseudopodia. Locomotion is the movement of the animals from place to place. : 14 ciliates balantidium coli kinetoplastida 1. leishmania donovani. Major organelles protozoan cells and their function. The Protozoa Intestinal flagellates Chilomastix mesnili Morphology - Trophozoite - 4 flagella (3 anterior, 1 associated with the cytostome; one nucleus, always located anteriorly.

(plasmagel) at the posterior end of the body. and ingestion of food due to parasitic life. Location in the body of the host. Axostyle - a supporting mechanism, a rod-shaped structure; not all flagellates have these. Protozoa - . It is performed in search of food, mate, and shelter or to escape from predators etc.
