Chytridiomycota

Phylum: Deuteromycota Commonly referred to as the Fungi. Imperfecti or imperfect fungi. Classification based on asexual stage because: Sexual reproduction rare, occurs only in narrow environmental parameters. Sexual phase of life cycle no longer exist.

Key Points

1. Deuteromycota do not possess the sexual structures that are used to classify other fungi.
2. Most deuteromycota live on land; they form visible mycelia with a fuzzy appearance called mold.
3. Recombination of genetic material is known to take place between the different nuclei after some hyphae recombine.

Deuteromycota is referred to as form-phylum because the divisions within the group are based on morphology and not on common phylogenetic background. A few imperfect fungi lack conidia and form only sclerotia. There is a tremendous variety of morphologically different conidia produced in the form- phylum Deuteromycota.

Fungi Imperfecti

Harpellales, order of fungi (phylum Glomeromycota, kingdom Fungi) with a vegetative body (thallus) consisting of single or branched filaments (hyphae). Members of Harpellales may occur in the gut or on the cuticle (outer covering) of crabs, beach fleas, boring gribble, and other arthropods.

Some examples of the Chytridiomycota are Allomyces, a water mold, Synchytrium endobioticum, a pathogen of potato, and Neocallimastix, a chytrid that lives symbiotically in the gut of herbivores, such as cattle.

Chytrids reproduce both sexually and asexually, which leads to the production of zoospores. Chytrids have chitin in their cell walls; one unique group also has cellulose along with chitin.

Summary

• Fungi cause three different types of human illness: poisonings, parasitic infections, and allergies.
• Many poisonous mushrooms are eaten by mistake because they look like edible mushrooms.
• Parasitic yeasts cause candidiasis, ringworm, and athlete’s foot.
• Mold allergies are very common.

Penicillin, which is produced by the sac fungus Penicillium, is used as an antibiotic to fight disease. Allergy medications and cortisone are products of fungi as well. Yeast, used in the making of bread and wine, bleu cheese and yogurt also contain beneficial fungi. Infectious fungi cause ringworm and athlete’s foot.

[a] all fungi have (1)cell walls made of chitin & are (2) heterotrophic by absorption. [b] most fungi are [1] multicellular (except yeast & class cyhtrids). [2] have a haploid life cycle; [3] reproduce sexually while others reproduce asexually.

Together with bacteria, fungi are responsible for breaking down organic matter and releasing carbon, oxygen, nitrogen, and phosphorus into the soil and the atmosphere. Fungi are essential to many household and industrial processes, notably the making of bread, wine, beer, and certain cheeses.

Let’s explore seven interesting facts about fungi.

• 1) Fungi Can Cure Disease.
• 2) Fungi Can Also Cause Disease.
• 3) Fungi Are Vital to the Environment.
• 4) Fungi Can Last for a Long Time.
• 5) Fungi Can Be Deadly.
• 6) Fungi Can Be Used to Control Pests.
• 7) A Fungus Is the Largest Living Organism on the Planet.

Interesting Facts about Fungi Scientists who specialize in the study of fungi are called mycologists. The fungi kingdom is more similar to the animal kingdom than the plant kingdom. The word “fungus” is a Latin word meaning “mushroom”. It is estimated that there are at least 1.5 million different species of fungi.

Probiotics are often called “good” or “helpful” bacteria because they help keep your gut healthy. You can find probiotics in supplements and some foods, like yogurt.

Bacterial cells are different from plant and animal cells. Bacteria are prokaryotes, which means they have no nucleus. A bacterial cell includes: Capsule: A layer found on the outside of the cell wall in some bacteria. Cell wall: A layer that is made of a polymer called peptidoglycan.
