Evolution of land animals THE LARGEST genetic study ever performed to learn when land plants and fungi first appeared on the Earth has revealed a plausible biological cause for two major climate events: the Snowball Earth eras‚ when ice periodically covered the globe‚ and the era called the Cambrian Explosion‚ which produced the first fossils of almost all major categories of animals living today. According to the authors of the study‚ Science‚ plants paved the way for the evolution of land

. Understanding the causes of infection 1.1 Identify the differences between bacteria‚ viruses‚ fungi and parasites. Bacterial and fungi infections are easy to cure with the use of antibiotics‚ where as viruses can be hard to cure or vaccinate against‚ such as the common cold. Bacteria can be found everywhere and anywhere Soil‚ Water‚ Plants‚ Animals‚ material and even deep in the earth’s crust. Bacteria feed themselves by making there food with the use of sunlight and water. We would not

CHAPTER III MATERIALS AND METHODS This research study used the process of extraction to test the effectiveness of Acapulco (Cassia Alata) leaves in killing or eradicating the fungi Microsporum canis. The raw material that the researchers used in the experiment is the Acapulco with the scientific name Cassia Alata. It belongs to the family of Leguminosae. It is a shrub which is erected and grew for about 2 meters tall. The leaves of the plant posseses fungicidal‚ insecticidal and pesticidal

temperatures effects the growth rate of the fungi Aspergillus oryzae. Most fungi’s tend to survive within the temperature range of 5-35oC‚ with the optimum depending on their normal environmental temperature. The fungi Aspergillus oryzae is heterotrophic which means they taken in their food from dead organic matter and cannot produce food for themselves and use the organic carbon in dead organic matter to grow. Temperature can influence shape of the enzyme within the fungi‚ which effects growth. Enzymes tend

The cell groupings of multicellular organisms that have a specific function are termed tissues and groups of tissues make up organs. 8. Protozoa ‚ algae and fungi are unicellular 9.

Oregano has carvacrol and thymol‚ which can kill fungi and these isomeric substances‚ that can be added to an oil-based paint as an additive to determine if oregano is an effective additive component for paints.

Whittaker divided all living things into five kingdoms- Monera‚ Protista‚ Fungi‚ Plantae‚ and Animalia. The main criteria for classification included o cell structure o thallus organisation o mode of nutrition o reproduction o phylogenetic relationship (evolutionary relationship) Kingdom Monera It includes all prokaryotes

compound-brightfield microscope. While we generally cannot see individual microorganisms with the naked eye‚ they are present in virtually every habitat known to man. Microorganisms can be prokaryotic—the bacteria or eukaryotic—the algae‚ protozoa or fungi. While viruses are acellular they are also studied in the scope of microbiology because they are small and because they infect cells. While most bacterial are unicellular they can also exist in colonial or multicellular forms. In this laboratory

about the Cordyceps because it’s one of the most interesting type of fungi I have ever heard about‚ mostly because I love zombie movies and this fungus was the inspiration to really popular game called “The last of Us.” I first heard about it in a BBC documentary “Planet Earth” years ago and I still remembered watching the scene of the so called “Zombie Fungi‚” being really fascinated by it. The cordyceps belong in the kingdom of fungi‚ different from plants and animals. Although some people claim the
