Phagocytosisfagstss Cellular ingestion engulfing food particles or foreign bodies by surrounding them with cytoplasm and forming a membranebound vesicle or vacuole containing the particlePinocytosispinstss Uptake of fluid rather than particulate material by endocytosis surrounds the fluid with cytoplasm to form a vesicle or vacuole Gr pinein to drinkkytos cavity or cellSchizogonyskizgn A form of asexual reproduction found in some protozoans An already multinucleated cell undergoes cell division that results in each daughter cell containing only one of the many nuclei present in the parent cell This is also referred to as multiple fission Gr schizein to cleave or splitgone birthSporogonysprgn A form of asexual reproduction where the fusion product of the male and female gamete the zygote undergoes multiple cell divisions that produce sporozites Found in animals in the protozoan phylum Apicomplexa Gr sporos seedgonos birthSchizocoelskizsl A true body cavity that forms by schizocoelus splitting of the mesodermSchizocoelusskizsls One of two ways that a body cavity forms within the mesoderm The other is enterocoelic pouching The block of mesoderm splits apart to create the coelomic space a characteristic of the protostomes Gr schizein to cleave or splitkoilos hollowPelliclepelikl The network of semirigid cell membrane thickenings found on the surface of some protozoans These are used to anchor either the locomotory flagella or cilia into the surrounding plasma membrane L pellicula skinKinetosomekintsm Structure that forms and anchors the axoneme of a cilium or flagellum in the plasma membrane also called a basal body Gr kinein to movesoma bodyDimorphic nucleidmrfik nykl Organization of the nuclear material typical of ciliates There is always a single small micronucleus and either one large or many macronuclei Micronuclei are involved in reproduction and the macronuclei are used by the cell to function Gr dis twomorphe shapePolyphyleticplifletik A taxon that includes animals from two or more distinct evolutionary lineages and may not include the ancestor of either Compare to monophyletic Grpolys manyphyle tribeLobopodlbpd Type of pseudopod consisting of both ectoplasm and endoplasm large thick and bluntended L lobus lobeGr podus footFilopodfilpd Type of pseudopod consisting of thin ectoplasm strands without any internal support and doesnt form a net or mesh with other pseudopods L filum threadGr podos footEctoplasmektplazm The outer cytoplasm of a cell or protozoan that has no organelles and is usually less fluid than the inner endoplasm Gr ektos outsideplasma formEndoplasmendplazm The inner cytoplasm of a cell or protozoan with organelles usually more fluid than the outer ectoplasm Gr endon withinplasma formMyone mmenm Strands of contractile myofibers found in single cells These allow the cell or a portion of the cell to contract in length and change its shape Gr myos musclenema threadMetazoanmetzn True multicellular organisms that exhibit all the characteristics of animals They have cells tissues and organs Gr meta after among or betweenzoon animalConjugati knjgonshn A form of sexual reproduction in ciliates Ciliophora During conjugation two ciliate protozoans join and the macronuclei disappear After meiotic divisions of the micronucleus the resulting genetic material is exchanged L con togetherjugare to joinChoanoc knytest This unique collarshaped cells whose flagella are responsible for generating the water current in the sponge As the flagella beat food particles are trapped against the microvilli that form the collar Choanocytes are also found in some colonial protists funnelkytosGr choanecavity or cellArchaeoc rkytest Cell capable of a variety of functions or of differentiating into a variety of cell types with different functions Examples include the wandering amebocytes in the mesohyl of a sponge Gr archein to beginkytos cavity or cellChoanode knrmdrm The layer of choanocyte cells lining the different parts of the aquiferous system in a sponge in the asconoid architecture the spongocoel in syconoid the radial canals and in leuconoid sponges the choanocyte chambers Gr choane funnelderma skin
