Taxonomy Review - KEY
A) VIRUSES: UNIT 2
1. Be able to identify and name the three main shapes of
viruses.
HELICAL POLYHEDRAL
COMPLEX
2. Know the difference between lytic and lysogenic life
cycles
Lysogenic: Reproduces viral nucleic acid without
damaging host cell.
Lytic: Trashes the cell by causing it to lyse as many
copies of virus are fully assembled.
B) KINGDOM MONERA: UNIT 2
1. Compare and contrast Prokaryotic Cell anatomy
with Eukaryotic Cell Anatomy.
Prokaryotic cells are smaller, they lack membrane
bound organelles and do NOT possess a true
membrane bound nucleus.
Eukaryotic cells are larger with membrane bound
organelles and a true kernel-like nucleus.
2. Compare and contrast Eubacteria, and
Archaebacteria.
Eubacteria (true bacteria) are commonly found
typical bacteria. Archaebacteria are a more
primitive bacteria that can tolerate more primitive
environments, like extreme pH, extreme high temps,
extreme salinity (salt)
3. Appreciate the important role of
CYANOBACTERIA.
Cyanobacteria are photoautotrophic bacteria and
are therefore capable of photosynthesizing their own
food. As a result they end up playing the very
important role of being producers in a number of
aquatic food chains.
4. . Identify and name the three main bacterial cell
shapes.
SHAPES just below
ARRANGEMENTS just above
5. Know the key differences in classifying bacteria
according to cell wall type.
The majority of bacteria are classified as being either
Gram Positive or Gram Negative.
Gram Negative bacteria have a thinNer cell wall, they
take up the Gram Stain SafriNine and they retain it to
take on a piNk appearance.
Gram Positive bacteria have a Thicker wall, they take
up the Gram Stain Crystal Violet to take on a
Purpleish colour.
C) KINGDOM PROTISTA: UNIT 3
1. Name and describe four phyla of “Zooplankton”
and name and identify one member for each
phylum.
A)
CILIOPHORA - Paramecium caudatum
B) ZOOMASTIGINA – Giardia
C)
SARCODINA – Amoeba proteus
D)
SPOROZOA – Plasmodium vivax
2. Name and describe three phyla of
“Phytoplankton” and name and identify one
member for each phylum.
A)
EUGLENOPHYTA – Euglena gracilis
B) PYRROPHYTA – Gonyaulax polyedra
C)
CHRYSOPHYTA – Diatoms
3. Give the proper phylum name for the following
“Fungi-like Protists”:
a) Cellular Slime Mold- ACrasiomycota
b) Acellular Slime Mold – Myxomycota
D) KINGDOM PLANTAE: UNIT 4
1. Name and describe three phyla of algae.
A)
RHODOPHYTA – Red Algae
B) PHAEOPHYTA – Brown Algae
C)
CHLOROPHYTA – Green Algae
2. Identify and name at least 5 members of Phylum
Chlorophyta.
A) Chlamydomonas – Unicellular
B) Volvox – Colonial
C) Spirogyra – Filamentous
D) Oedogonium - Filamentous
E) Ulva – Multicellular
3. Name and describe the phylum of non-vascular
terrestrial plants and name three members that belong
to this phylum.
BRYOPHYTA – Mosses, Hornworts and Liverworts
4. Name the phylum of vascular terrestrial plants, identify
and name and describe the characteristics of the most
primitive group (non-seed bearing) of plants in this
phylum.
TRACHEOPHYTES : all vascular (xylem and phloem)
plants. The non-seed bearing plants in this phylum belong
to Subphylum Pteridophyta – Ex Ferns
5. Name the two major groups of seed-bearing
Tracheophytes (subphylum Spermopsida).
A) GYMNOSPERMS : Ginkoes, Cycads and CONIFERS
B) ANGIOSPERMS : Flowering plants including all
monocots and dicots.
6. Identify and name at least 6 members for each of these
groups.
Conifers: Spruce, Cedar, Hemlock, Pine, Juniper, Fir
Angiosperms: Cherry, Oak, Apple, Tomatoes, Beans
7. Name and compare the differing characteristics of the
two sub-classes of Angiosperms (monocots vs. dicots)
MONOCOTS : MONO – "SSPORRT"
SS- Scattered vascular bundles in the Stem.
P – Parallel venation in leaves
O – One cotyledon
RR – Ringed vascular tissue in Roots
T – Flower parts in multiples of Three.
DICOTYLEDONS – No good acronym but:
-Ring pattern of vascular bundles in stem
- Branched venation in leaves
- Two cotyledons
- X- Shaped Xylem in root.
- Flower parts in Multiples of 4 or 5.
