Classification of Living Things
The classification scheme used in Biology is called this.
Taxonomic Classification or Taxonomy
What do most bacteria use for locomotion?
Flagella
What is the main means of locomotion employed by organisms in each of the following phyla:
Sarcodina, Zooflagellates, Ciliophora
Sarcodina: pseudopods
Zooflagellates: flagella
Ciliophora: cilia
Why are bryophytes relatively small?
They have no vascular system
Yes
Name the classification groups in order from largest to smallest (most specific).
domain, kingdom, phylum, class, order, family, genus, species
What is the main mode of reproduction of bacteria?
Asexual reproduction called binary fission
Name 2 pathogenic protists.
Entamoeba histolytica
Trypanosoma
Balantidium coli
Plasmodium
Toxoplasma
What type of life cycle do plants exhibit?
alteration of generations
Why is the bottom of a leaf typically a lighter shade than the top of the leaf?
The spongy mesophyll is typically on the underside of the leaf, and it is usually a lighter shade of green.
An organism is a multicellular decomposer made of eukaryotic cells. To what domain and kingdom does it belong?
domain Eukarya; kingdom Fungi
Bacterial conjugation does not result in offspring. How does conjugation occur, and how does it affect offspring?
Conjugation passes a trait from one bacterium to another via a small strand of DNA called a plasmid. If the trait, allows the bacteria to survive when they otherwise would not, it will increase the population.
Only 10% of an iceberg is visible above the surface of the ocean, how is an iceberg like a fungus?
Typically, we only see the fruiting body of a mushroom. That part is only a small fraction of the total mushroom because the mycelium is the largest component of the mushroom.
What is the dominant generation in the moss life cycle? In the fern life cycle?
Mosses: gametophyte generation
Ferns: sporophyte generation
These are 2 kinds of structures used by vascular plants for the transport of water and nutrients.
xylem and phloem
An organism is a single-celled prokaryotic autotroph that lives in extremely hot environments. To what domain does it belong?
Domain Archae
The technical names for the three common bacterial shapes (spherical, rod-shaped, and helical) are these.
coccus, bacillus, spirillum
What phylum contains fungi that do not have a known mode of sexual reproduction?
Phylum Deuteromycota
Name the male and female reproductive organs of a flower.
Male: stamen
Female: carpel
What type of tree has an abscission layer?
a deciduous tree
If a virus used DNA as its genetic material, is it alive?
No, a virus cannot reproduce on its own
Name one pathogenic fungus and the malady it produces.
rusts--crop damage
smuts--crop damage
ergot of rye--death
Cryphonectria parasitica--chestnut blight
Ophiostoma ulmi--Dutch elm disease
Synchytrium endobioticum--potato wart
Candida--thrush
What function do cotyledons perform before germination?
feed the embryo
What are two differences between monocots and dicots
~parallel leaf veins vs. branching leaf veins
~vascular bundles scattered in stem vs. Vascular bundles formed in a ring
~Fibrous root system vs. taproot
~Flower parts in multiples of 3 vs. multiples of 4-5
