Mycology

An organism that is unable of synthesizing carbohydrates from inorganic sources, requires preformed organic compounds produced by other organisms.

As saprotrophs particularly as decomposers fungi are essential components of the carbon cycle and are among the few organisms that ca break down lignin

Using the common bread mold neurospora crassa developed the classical concept of one gene one enzyme

Branching filamentous structures of fungus. They grow at the tips

Is the vegetative growth of fungus so it's a group of hyphae

• Regular cross-walls formed in hyphae
• Hyphae with septum are known as septate

The hyphae lacks a septum

The body of a fungus

- the asexual stage

It is a spore formed via asexual reproduction commonly called a conidium

The sexual stage

• A spore formed via sexual reproduction
• - type of spore varies by phylum ex ascospore basidiospore oospore

Is a sexual stage of fungi where two cells fuse together, the nuclei do not fuse however only the cytoplasm

This occurs after plasmogamy and the two nucleuses fuse together. This is then followed by meiosis reduction division

A cell that has gone through plasmogamy and have two nucleuses that are haploid

• They asexually produce sporangiospores
• - non motile spores are aplanospores
• -motile spores are zoospores

• They produce motile zoospores and germinate directly
• -mode of germination is controlled by environmental conditions like temperature

They are specialized hyphae that produce conidia under specific environmental conditions

Ascomycota and basidiomycota
