is a specialized fungus in the soil which forms close associations with the roots of a vascular plants * In other temperate and boreal successional systems arbuscular mycorrhizal fungi are the primary mycorrhizal associate in early succession‚ whereas in older soils the main associates are ectomycorrhizal fungi (Piotrowski‚ 2008). Arbuscualar Mycorrhizae: Arbuscular mycorrhiza (AM) is the predominant and ancestral type of mycorrhiza in land plants. It’s root cells have arbuscules (tree

Identify the differences between bacteria‚ viruses‚ fungi and parasites? Bacteria : Bacteria are one cell structures that multiply rapidly and can become a colony of 2 million within 2 hours. Viruses : Visible can only be seen with an electron microscope they can float in the air‚ sit on a door handle or remain non-living. They become active when they are allowed access to a living cell. Fungi : Not all fungi can cause us problems‚ Fungi are plant-like structures that survive on dead organic

organize information on what we are and what resides with us. When we place every living creature into one of the five kingdoms it better helps us understand the world around us and it ’s habitants. The five kingdoms include: Moneran‚ Protist‚ Fungi‚ Plantae‚ and the one we call home‚ Animalia. 1. Monera The simplest of all organisms is the bacteria of the Moneran kingdom. They are broken down into two types: Eubacteria and Archaebacteria. Eubacteria is known as the “true bacteria” which

Gene Mapping in Ascospore Sordaria Cultures by Recombination Abstract The laboratory experiment demonstrates the process of meiosis using the Sordaria Fimicola fungi. Meiosis is important because it is the process that generates diversity in genetics. A wildtype was crossed with two mutant types: tan and grey. In order to exhibit recombination‚ the sequence of ascospores needed to result in a 2:2:2:2 or 2:4:2 sequence. From the crossover

Bacteria multiplies by its self to progress and spread. Unlike other infections such as viruses‚ fungi or parasites bacteria is not always harmful in fact in many cases bacteria can be useful to the living organisms‚habitats

The term antibiotic has been defined in many different ways. According to Thomashow‚ L.S and Weller (1995)‚ antibiotics defined as a chemically heterogeneous group that small organic molecules of microbial origin that at low concentration‚ are deleterious to the growth or metabolic activities of other

far smaller than bacteria. They are enclosed in a protein coating which makes them more difficult to destroy. The basic unit of Fungi is a hypha which is a hollow tube. The hypha threads spread out over and into the food material making a visible mesh or mycelium. Some fungi form together to create toadstools. They spread by releasing spores into the environment. Fungi can cause diseases in humans in the form of yeasts such as ringworm‚ athlete’s foot and other diseases. A parasite is an organism
