Things to Study for First Exam
| Question | Answer |
|---|---|
| What is the anatomy of a sponge? | Ostium, Osculum, and spongocoel |
| What are the major animal phyla? | phylum Porifera, phylum Cnidaria, phylum Platyhelminthes, phylum Nematoda, phylum Annelida, phylum Arthropoda, phylum Mollusca, phylum Echinodermata, phylum Chordata |
| Kingdom Protista | subkingdom protozoa |
| phylum sarcomastigophora | subphylum sarcodina |
| What are the six classifications of humans? | notochord, dorsal hollow nerve cord, perforated pharyngeal gill slits, ventral heart, thyroxin synthesis, post anal tail |
| Cilia | eyelash like structures that move back and forth |
| phagocytosis | the ingestion of food by surrounding it then storing in within a pocket |
| cell anatomy | cell membrane, cytoplasm, nuclear membrane, nucleoplasm, nucleolus |
| cell organelles | DNA, mitochondria |
| taxonomy | the description, identification, naming, and classification of organisms. |
| What are the twelve -ologies? | Biology, zoology, cytology, histology, mammalogy, primatology, ornithology, paleontology, herpetology ichthyology, entomology, endocrinology |
| Biology | the study of life |
| Zoology | the study of animals |
| Cytology | the study of cells |
| Histology | the study of tissues |
| Mammalogy | the study of mammals |
| Primatology | the study of primates |
| Ornithology | the study of birds |
| Paleontology | the study of fossils |
| Herpetology | the study of reptiles |
| Ichthology | the study of fish |
| Entomology | the study of insects |
| Endocrinology | the study of hormones |
| Binomial Nomenclature | giving two names to an organism |
| Hierarchy of Taxonomy | Kingdom, phylum, subphylum, class, order, family, genus, species |
| Classes of Cnidaria | class Hydrozoa, class Scyphozoa, class Anthozoa |
| class Hydrozoa | has a dominant polyp stage, has 1800 spp., produces nematocysts with cnidocil |
| class Scyphozoa | has a dominant medusa stage, produces nematocysts without cnidocil, has 360 spp. |
| class Anthozoa | only has a polyp stage, produces nametocycsts without cnidocil, its polyp is heavier than the hydrozoan polyp, has 6500+ spp. |
| pseudopodia | a temporary protrusion of the protoplasm, as of certain protozoans, usually serving as an organ of locomotion or prehension. |
| types of larvae | amphiblastula and planulae |
| nematocysts | an organ in coelenterates consisting of a minute capsule containing an ejectable thread that causes a sting. |
| Tissues | Squamous epithelium, Connective tissue, Vascular tissue, Muscular tissue, Nervous tissue, Reproductive tissue |
| monoecious | having both male and female organs in the same individual; hermaphroditic. |
| dioecious | having the male and female organs in separate and distinct individuals; having separate sexes. |
| phylum Platyhelminthes classes | class Turbellaria, class Trematoda, class Cestoda |
| phylum Platyhelminthes | has bilateral symmetry |
| sexual dimorphism | biology differences in appearance between the males and females of a species |
| radial symmetry | a basic body plan in which the organism can be divided into similar halves by passing a plane at any angle along a central axis, characteristic of sessile and bottom-dwelling animals, as the sea anemone and starfish. |
| bilateral symmetry | a basic body plan in which the left and right sides of the organism can be divided into approximate mirror images of each other along the midline. |
| spongin | a fibrous horny protein that forms the skeletal framework of the bath sponge and related sponges |
| gastrodermis | the inner cell layer of the body of an invertebrate. |
| epidermis | the outermost living layer of an animal, usually composed of one or more layers of cells. |
| cell | a usually microscopic structure containing nuclear and cytoplasmic material enclosed by a semipermeable membrane and, in plants, a cell wall; the basic structural unit of all organisms. |
| organ | a grouping of tissues into a distinct structure, as a heart or kidney in animals or a leaf or stamen in plants, that performs a specialized task. |
| plylum Porifera classes | class Calcerea, class Hexactinellida, class Demospongia |
| How many layers of cells are present in sponges? | 6 - 7 layers |
| What advantages do sponges have over the Protozoans? | They divide their chores up to get through life |
| What are the parts of a light microscope? | ocular lenses, nosepiece, objective lenses, slide clip, mechanical stage, iris diaphragm, lamp, coarse focus knob, slide positioning knobs, fine focus knob, power switch, lamp power adjustment |
| Ocular lenses | Used to view an object on a slide |
| Nosepiece | used to spin around the different powers of the objective lenses |
| slide clips | holds the slide in place |
| mechanical stage | used to place the slide on |
| iris diaphragm | used as a mirror of the object to be seen |
| lamp | brightens the objects and makes is easier to see |
| slide positioning knobs | used to move to slide back or forth and left or right |
| power switch | turns on the light microscope |
| lamp power adjustment | dims or brightens the light |
| What is the function of Dissecting Microscope? | To closely view an animal while dissecting it |
| What are the parts of a light microscope? | ocular lenses, nosepiece, objective lenses, slide clip, mechanical stage, iris diaphragm, lamp, coarse focus knob, slide positioning knobs, fine focus knob, power switch, lamp power adjustment |
