Study Notes
- Quercus rubra is the correctly written scientific name.
- Kingdom-phylum-class-order represents the correct arrangement of taxa from most to least inclusive.
- Binomial nomenclature refers to the practice of giving organisms two names.
- Eukaryotes include all organisms in the kingdoms Protista, Plantae, Fungi, and Animalia.
- In the name Ursus maritimus, the first word refers to the genus, thus, "the first word in the name refers to the species" is false.
- Different common names for an organism may exist based on the area and language.
- Gram staining differentiates bacteria based on the staining reaction of the cell wall.
- Chemoautotrophic bacteria utilize reduced gases like methane as an energy source.
- Prokaryotic does not describe a virus.
- A portion of DNA makes up the bacterial plasmid.
- Bacteria reproduce through binary fission.
- Chemoheterotrophs make up most bacteria, including major decomposers and pathogens.
- Sarcodinians classify amoebas, foraminiferans, radiolarians, and heliozonas.
- Phytoplankton includes single-celled photosynthetic protistans like euglenoids, chrysophytes, and dinoflagellates, and are members of the "pastures" of most aquatic habitats.
- Diatom earth deposits are used for insulation, abrasives, and pool filters.
- Giant kelp is the common name for Macrocystis, a species common off the coast of California.
- Motility of the trophozoite is the major organizing factor of protozoans.
- Color is the major organization factor of algae.
- Chitin is a hard substance found in the cell walls of most fungi.
- The main component of the fungi cell wall is different than the cell wall seen in bacteria or plants.
- Fungi are not primarily classified based on their colors.
- The lack of green color in mushrooms does not indicate that photosynthesis has ceased.
- Treatments for fungal diseases do not aim to keep the affected area moist and warm.
- Cotyledon number in their seeds is how angiosperms are classified into two major divisions.
- Conifers are mostly found in the north temperate zones.
- Sporophyte is the dominant generation in vascular plants.
- The fern frond most closely resembles a leaf.
- Gymnosperms and angiosperms do not have a single spore type.
- Photosynthetic cells make up mesophyll.
- Fibrous roots best describe the root system of monocot grasses.
- Root hairs primarily absorb water and minerals.
- Taproots reach deep into the soil.
- Xylem conducts water and ions, while phloem conducts food.
- Vascular cambium produces new xylem growth, resulting in growth rings in woody stems.
- Cephalization concentrates sensory organs anteriorly.
- Exclusive reliance on sexual reproduction is not a characteristic of the animal kingdom.
- Nematocysts are the stingers found in cnidarians' tentacles.
- Sea anemones are typically not about the same size as hydra.
- Radial symmetry describes the jellyfish's body.
- Monoecious organisms produce both sperm and eggs.
- Planarians move away from light.
- Sessile animals remain attached to an object.
- Burrowing is an adaptation facilitated by cephalization in earthworms.
- Earthworm clitellum produces a mucus sheath.
- Aortic arches link the major blood vessels near the anterior of the earthworm.
- All echinoderms are marine.
- The water vascular system allows the sea star to be rigid and flexible.
- The sea star's nervous system has no brain, but an extensive nerve net.
- Being parasitic is not a major characteristic of Echinodermata.
- One pair of antennae is a characteristic of all insects.
- Torsion occurs during larval development of snails.
- Birds and mammals have a four-chambered heart.
- No amphibians entirely escape dependence on aquatic habitats.
- Migration in birds is mainly due to depleted feeding grounds.
- A lateral line is not common to all vertebrates.
- Vertebrates have highly efficient circulatory systems, and complex nervous systems and sensory organs.
- Birds use feathers in all ways given (flight, insulation, display).
- Gill slits function in both respiration and food trapping.
- Slow swimming contributes to grey whales having the heaviest parasite load.
- Mammals' exceptional learning ability and memory are attributed to their well-developed cerebral cortex.
- Reptiles are fully independent of bodies of water in reproduction.
- The California sea otter has the world's thickest fur, and the entrapped air provides more than one of the options given (insulation, buoyancy).
