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
1. Problem, Information, Hypothesis, Experiment,
Data, Conclusions are the steps of the scientific
method.
2. Lab tools are: Forceps, Beaker, Scissors,
Dissecting Tray, Pointer, Erlenmeyer flask,
Graduated Cylinder
3. The Lab Drawing Rules are: include lines to the
right, no arrows, no underlining, you must label
all parts.
Cell Theory and Cell Processes
4. Cell  Tissue  Organ  Organ System
5. Eukaryotic cells HAVE A NUCLEUS. Prokaryotic
cells DO NOT HAVE A NUCLEUS.
6. 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
10.Evolution is gradual changes over time.
11.Charles Darwin developed the Theory of
Evolution.
12.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
19.Seedless plants use SPORES to reproduce.
20.Plants are EUKARYOTES because their cells
have a nucleus.
21.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.
