Zoology Ch. 8
Vocabulary for Zoology Ch. 8
| Question | Answer |
|---|---|
| The protozoan phylum characterized by members having an apical complex for penetrating host cells. | apicomplexan |
| Asexual reproduction in protists in which cytoplasmic division follows mitosis to produce two new protists. | binary fission |
| organisms that include: cilia for locomotion,rigid pellicle and more or less a fixed shape and distinct cytosome | ciliate |
| A form of sexual union that ciliates use to mutually exchange haploid micronuclei. | conjugation |
| marine flagellated protozoa that contain varioius pigments such as chlorophyll | dinoflagellate |
| The outer, viscous cytoplasm of a protist. | ectoplasm |
| The inner, fluid cytoplasm of a protist. | endoplasm |
| Modified mitochondria that lack functional electron transport chains and hence cannot use oxygen to help extract energy from carbohydrates. | mitosome |
| Asexual reproduction by the splitting of a cell or organism into many cells or organisms. | multiple fission (schizogony) |
| A thin, frequently noncellular covering of an animal. | pellicle |
| The study of protists. | protistology |
| a complete organism in which all life activitiesare carried on within a single plasma membrane | protozoan |
| A protective structure in the ectoplasm of some ciliates. | trichocyst |
| A large polyploid that regulates daily metabolic | Macronucleus |
| One or more smaller are the genetic reserve of the cell | Micronuclei |
| Multiple fission of an asexual stage in host cells to form many more indivduals | Schizogony |
| Begins the sexual phase of life cycle | Gametogony |
| Zygote undergoes meiosis and the resulting cells divide repeatedly by mitosis | Sporogony |
| When feeding and moving they form temporary cell extensions | Pseudopodia |
| Broad cell processes containing ectoplasm and endoplasm and are used for locomotion and engulfing food | Lobopodia |
| Contain ectoplasm only and provide a constant two-way streaming that delivers food in a conveyor-belt fashion | Filopodia |
| Similar to filopodia, branch and rejoin to form a netlike series of cell extensions | Reticulopodia |
| Thin, filamentous, and are supported by a central axis of microtubules | Axopodia |
| Protist have a single,large mitochondrion that contains an organized mass of DNA | Kinetoplast |
