Protozoa cell structures
Give this one a try later!
-Plasmalemma - protozoan membrane
-Pellicle - membranes with bands of protein to provide rigidness
-Shape can also be created by outer gel-like layer (ectoplasm) and inside
fluid in cytoplasm (endoplasm)
Phage life cycle
Give this one a try later!
, -virulent phages: lead to death of host cell by lysis
-temperate (latent) phages: become part of host genome until induced to
start making new viruses
Deltaproteobacteria
Give this one a try later!
-gram (-) proteobacteria
-small class
-sulfate reducing bacteria
-desulfovibro orale- periodontal disease
-parasitic Bdellovibro app.
-soil dwelling Myxobacteria "slime bacteria"
green sulfur bacteria
Give this one a try later!
-phototrophic bacteria
-oxidize sulfide
Oomycetes (water molds)
Give this one a try later!
, -similar to fungi but have cell walls composed of cellulose and are
generally diploid
-chromalveolata
-Phytophthorainfestans - potato blight
Helminths
Give this one a try later!
-multicellular parasitic organisms commonly called worms or flukes, posses
organ systems
-have limited digestive tracts, nervous systems, and locomotion
-complex reproductive cycles and multiple life stages: monoecious; only
one sex (both male and female organs), dioecious; either male or female
-groups: roundworms (phylum Nematoda) and flat worms (phylum
Platyhelminthes)
Euglenozoa
Give this one a try later!
-photo & non-photosynthetic;
-Cells have two flagella, a stigma (eyespot), & chloroplast (if applicable)
-Generally non-pathogenic with exception: Genus Trypanosoma - agent for
African sleeping sickness and Chagas disease.
Protozoa
Give this one a try later!
, -huge variety of unicellular, non-photosynthetic, motile eukaryotic
microbes
-Life stages: 1.trophozoites (feeding and growing stages) 2.cysts
(encapsulated stage to protect against harsh environments)
-reproduce asexually and sexually
-prominent groups: amoebozoa, excavata, and chromalveolata
HeLA cell lines
Give this one a try later!
-immortal cell line
-obtained from cervical cancer patient Henrietta Lacks in 1951
-cells still alive today
Neutralism
Give this one a try later!
-both are unaffected
-ex:spores in soil
Viral Growth Curve (bacteriophage)
Give this one a try later!
-Bacteriophages can be grown in dense layer of bacteria (bacterial lawn)
-four phases
1.Inoculation - virus causes infection
2.Eclipse - virus binds and penetrates (no virions detected)
