Classification Biology I. Introduction A.Background 1. Why classify organisms? 2. How do you classify?
B.Organization K, P, C, O, F, G, & S
II. Viruses A.Structure
The parts == protein (capsid , landing gear, and injector) surrounding a nucleic acid (genome= can be DNA or RNA) Figure 10.24 & 25
1. Lytic = inject, insert, take over, direct, and destroy Figure 10.26
2. Lysogenic = same except hide for a time then lytic Figure 10.26
C.Uses 1. Vaccines 2. Gene Vectors
III. Kingdom Moneran A.Structure
Monerans = prokaryotes Can be spherical , rod, or helical Figure 15.11
Monerans == autotrophic (chemo.or photosynthetic) or heterotrophic (photo. or chemo.) Table 15.1
Strategies == saprophytic, parasitic, nitrogen fixers or symbionts Classed as obligate aerobic, facultative anaerobic, or obligate anaerobic
Monerans by flagella (either by chemo-taxis or photo-taxis) Figure 15.12
Binary Fission Endospore Formation Figure 15.13
1. Bacteria == beneficial to pathogenic Figure 15.11b Figure 15.15
2. Archae == oldest Methanogens Thermoacidophiles Figure 15.9
IV. Kingdom Protistan A.General Characteristics
Protisitanssingle celled to multi-celled divided into protozoa and algae.
B.Major Taxa 1. Protozoa
a. Single celled algae == autotrophic, pigments & store glucose i. Euglenophyta== chlorophyll & paramylum
ii. Chrysophyta = golden algae silica shell flagellated, fucoxathin, & oil Diatoms
iii. Pyrrophyta = red algaeB-carotene and xanthophylls, cellulose Dinoflagellates
b. Multi-celled algaeautotrophs seaweeds. i. Chlorophytachlorophyll, starch, mutualistic
ii. Phaeophytabrown algae with chlorophylls and xanthophylls, oil, parts (holdfast, stipe, and blades),and alteration of generation
iii. Rhodophyta red algae with chlorophylls, carotenoids, and phycobilin, plusjelly-like agar
C.Uses 1. Protozoa 2. Algae
V. Kingdom Fungi A.General Characteristics
Septate Non-septate Mycelium in nature
Fungi have chitin cell walls -- heterotrophicscavengers Some can be predatory or mutualistic.
1. PhylumChytridiomycotawater molds with flagellated spores, clearsex gametes, chitin cell walls
2. PhylumZygomycotaterrestrial molds, saprobesasexual or sexual, chitin, Food destroyers!
3. PhylumAscomycotasac-like fungi, asexual or sexual spores and dikaryonic
4. PhylumBasidiomycota. “True shrooms” or club fungi sexual basidiocarp (What you eat!) Dikaryonic
VI. Kingdom Plantae A.General Characteristics
Plants == terrestrial autotrophs (aquatic, parasitic, or carnivorous) from Chlorophyta? chlorophyll a and b, starch, cellulose cell walls
