Biology 12 3rd Exam Reviewer Exercise 9: The Prokaryotes Prokaryotes are subdivided into archaebacteria and eubacteria. Archaebacteria - no peptidoglycan in cell wall Ex. Halob acterium Eubacteria - has peptidoglycan in cell wall Eubacteria - can be differentiated by Gram staining Gram positive: purple-blue‚ mostly peptidoglycan susceptible to penicillin Gram negative: pink-red‚ less peptidoglycan‚ has lipopolysaccharides‚ susceptible to EDTA Gram negative can be further differentiated into

Write an essay on the role of fungi in wood and litter decay. [40] Fungi‚ together with bacteria‚ are the principal decomposers in the biosphere. They break down organic materials and return the substances locked in those molecules to circulation in the ecosystem. Fungi can break down cellulose and lignin‚ an insoluble organic compound that is one of the major constituents of wood. By breaking down such substances‚ fungi release carbon‚ nitrogen‚ and phosphorus from the bodies of living

Coccidioides immitis Coccidioides immitis is a member of the Kingdom‚ Fungi; Phylum‚ Ascomycota; Class‚ Euascomycetes; Order‚ Onygenales; Family Onygenaceae; and the Genus Coccidioides. Coccidioides immitis are thermally dimorphic fungus that reproduces by arhroconidia‚ swelling of arhroconidia in vivo into spherules (which burst and release endospores.) The fungi is found mainly in warm dry areas with low rain fall‚ high summer temperatures‚ and low altitude. C. immitis is geographically limited

2.4.3.1. Fusarium Spp. : - is one of the most important genera of plant pathogenic fungi‚ with a record of devastating infections in many kinds of economically important plants. The genus Fusarium belongs to the Ascomycota phylum‚ Ascomycetes class‚ Hypocreales order‚ while the teleomorphs of Fusarium species are mostly classified in the genus Gibberella‚ and for a smaller number of species‚ Hemanectria and Albonectria genera (Moretti‚ 2009). Unlike most Aspergillus spp. and Penicillium spp.‚ Fusarium

by scientists on Evolution Canyon‚ it was found that the recombination for the organism was occurring much more frequently on the South-Facing slope than the North-Facing slope The organism that was primarily studied was the Sordaria fimicola‚ an Ascomycota fungus that can be easily used to see the genetic diversity and recombinant frequency due to its spore combinations. There are three types of spore carriers (asci)‚ which come about depending on what chromosomes recombine and what happens to the

* Fungi are Eukaryotic‚ mainly multi cellular organisms includes molds and mushrooms * fungi lack chlorophyll * they are heterotrophic and cell walls contain chitin * more closely related to animals * supergroup Unikonta categorized as opisthokonts bc of single posterior flagellum * heterotrophs‚ secrete enzymes which digest food outside the body‚ the broken down food is then absorbed by hyphae * 3 types of fungi * decomposer fungi‚ absorb nutrients

conidia‚ and sporangiospores are formed in this asexual process. Fungus can be classified many different ways with complicated systems. Mycologists‚ mycology scientists‚ usually use a simple system with four main groups. Oomycota‚ Zygomycota‚ Ascomycota‚ and Basidiomycota are the main phyla which fungi are classified into. There is a fifth major phylum‚ Deuteromycota‚ also called Fungi Imperfecti‚ in which a few organisms are loosely grouped into because they are difficult to classify‚ many of

Module 04 Homework Assignment Use the information presented in this module along with additional outside research to answer the questions: 1 Discuss the two methods of viral replication. The two methods of viral replication are done in animal viruses. The first method deals with DNA viruses and the second is RNA viruses. In the DNA virus‚ the viral DNA enters the nucleus of the host cell. Than it is transcribed into mRNA and leaves the nucleus into the cytoplasm. The early mRNA then translates
