Sordaria mapping using spore colors Courtney Smith Lab Partner: Ginni Leeman Lab Instructor: Emily Ashe Lab Section: Bio 240 Date: 10-6-17 Abstract Sordaria is an interesting fungus in the facts that it sexually reproduces and goes through a cycle called meiosis. Meiosis goes through quite a few phases starting with Prophase I and going all the way to Telophase II and consists of a process called crossing over or recombination. The purpose of this experiment was to determine

Sordaria fimicola is a microscopic fungal species that produces ordered tetrads. It is commonly used in classrooms because it lacks conidiospores, has a short generation time with matching genotype and phenotype, has known color genes that permit tetrad analysis, easily observable crossing over effects, and does not undergo spindle overlap. In S. fimicola, meiosis occurs in the ascus. The fungus is a haploid organism for the majority of its life. It only becomes diploid when mycelia of two unlike

The purpose of this lab experiment is to observe examples of asexual and sexual structures of different types of fungal structures. This experiment is to also compare and contrast sexual structures of the three major fungi divisions; zygomycota, ascomycota, and basidiomycota. Hypothesis: I expect that the three sexual structures of fungi will appear to be visibly different and reflect the shapes they are known to have. Methods: The microscope was brought over to the table and the plastic cover was

Ascomycota Structure - Because these type of the fungi belong to the Phylum Ascomycota.Therefore, they have are characterised by the formation of an ascus. Which is a sac-like structure and they have haploid ascospores within them. Description - Ascomycota are also known as sac fungi, a phylum of fungi and they have saclike structure (ascus) and in there you can find four to eight ascospores in the sexual stage. Characteristics - They belong to the Phylum Ascomycota and they are

This question requires knowing the Beadle and Tatum’s experiment with Neurospora crassa and the results. Neurospora crassa, which is a type of bread mold of the phylum Ascomycota, has provided a rich source of knowledge on “biosynthetic pathways.” Neurospora crassa was perfect substance for biosynthetic pathway experiment. Because it was cheap, easy to grow, and more importantly it is haploid for most of its life. Since Neurospora crassa is haploid, there exists only one copy of each gene so that

Infectious diseases has most likely had the most effect on the world after the start of contact by Columbus and his men. Positively illness was the best weapon that Europeans conveyed to America. The staggering impact of sickness on Native people groups was for the most part because of the organic detachment and the restricted interruption of irresistible ailments in America before A.D. 1492. The weapon of ailment was not very much perceived by Europeans, nor purposefully utilized as a part of the

YEAST Yeasts are eukaryotic unicellular fungi which reproduce by budding or fission. Yeasts are very small, typically 5 to 10 microns (1 micron = 10-4 centimeters) which is around 5 times the size of most bacteria. Yeast cell membranes acts as impermeable barriers against hydrophilic molecules to prevent the mixing of the cytoplasm and external environment. Around 7.5 n thick, the cell membrane is composed of a lipid bilayer (Walker, 1998). As with all eukaryotic membranes, the lipid bilayer

Fungal diseases have been recently introduced into the medical field. Fungi are a part of the domain Eukarya, where it once was considered in the plant kingdom. The domain Eukarya is consistent with eukaryotic organisms that contain a nucleus and other membrane-bound organelles. Fungal diseases are more difficult to treat compared to antibiotics for bacterial diseases because the fungus and the host are eukaryotic organisms. Therefore, any treatment of the fungus may affect the host too and can develop
