Period 10 Questions and Answers Life Science Review Period 10 Questions and Answers

PHYLA IN THE ANIMAL KINGDOM PORIFERA- no symmetry, sponges CNIDARIA- radial symmetry, jellyfish PLATYHELMINTHES- flat worms, planarian NEMATODA- roundworms, Pinworm ANNELIDA- segmented worms, earthworm MOLLUSCA- soft bodies, often have a shell ECHINODERMATA- tube feet, sea star ARTHROPODA- “jointed feet,” exoskeleton, insects CHORDATA- notochord, dorsal nerve cord, gill slits

Science through Inquiry Problem, Information, Hypothesis, Experiment, Data, Conclusions are the steps of the scientific method. Lab tools are: Forceps, Beaker, Scissors, Dissecting Tray, Pointer, Erlenmeyer flask, Graduated Cylinder The Lab Drawing Rules are: include lines to the right, no arrows, no underlining, you must label all parts.

Cell Theory and Cell Processes Cell  Tissue  Organ  Organ System Eukaryotic cells HAVE A NUCLEUS. Prokaryotic cells DO NOT HAVE A NUCLEUS. Photosynthesis: 6CO2 + 6H2O  C6H12O6 + 6O2 Respiration: C6H12O6 + 6O2  6CO2 + 6H2O

Genetics 7. Cells are the basic units of life. 8. A genetic disorder is an abnormal condition that a person inherits through genes or chromosomes. 9. A diagram that shows the possible genotypes of an offspring between two parents is a PUNNETT SQUARE.

Punnett Square Example

Evolution and Natural Selection Evolution is gradual changes over time. Charles Darwin developed the Theory of Evolution. Natural selection is when the best adapted organisms survive and reproduce. The color of the peppered moth helping it to survive in its environment is an example of natural selection.

Classification 13. A scientific name is written with the Genus capitalized, species lowercase, and both words underlined (Genus species) 14. Cells  Tissues  Organs  Organ systems 15. Binomial nomenclature is the naming system developed by Linnaeus.

Simple Organisms 16. A virus is a nonliving particle that enters and reproduces inside a living cell. 17. Algae are plant like protists. 18. Spores are tiny cells that are able to grow into a new organism. Fungi use these to reproduce.

Plant Kingdom Seedless plants use SPORES to reproduce. Plants are EUKARYOTES because their cells have a nucleus. Vascular plants have vascular tissue, which helps transport materials throughout the plant.

Animal Kingdom 22. Phyla in the animal kingdom are: PORIFERA, CNIDARIA, PLATYHELMINTHES, NEMATODA, ANNELIDA, MOLLUSCA, ECHINODERMATA, ARTHROPODA, CHORDATA 23. Phylum Chordata includes animals that: had gills slits at some point in their lives, have a dorsal nerve cord, and a notochord. 24. The largest population that an area can support is the CARRYING CAPACITY.
