important as pathogens, decay organisims, food, and in industrial processes such as brewing, wine and cheesemaking; have cell walls of chitin (a polysaccharide); heterotrophic; single celled or filamentous; non motile
general characteristics of fungi part 2
usually have filamentous structure called hyphae; all are Gram positive; all produce spores
mycology
study of fungi
mycosis
any disease caused by a fungus
function of fungal spores
1. growth and survival 2. long-distance dispersal (can be pushed in different habitats by water and wind)3. creating new genetic combinations (sexual spores only)
septate hyphae
have cross walls or septals that make a division between cells
aseptate hyphae
have a chain of cells with no cross wall
mycelium
a mass of hyphae (a whole fungus) visible to the naked eye
mold
a fungus that grows as a mass of filamentous hyphae
yeast
a fungus that grows as single, oval cells they reproduce by budding (an unequal cell division) or by asexual spores
budding
an unequal cell division (how yeasts reproduce)
dimorphism
having two forms
general characteristics of algae
Kingdom Protista; have cell walls; single or multicellular; autotrophic (photosynthetic); no specialized tissues; make the most of the atmospheric oxygen; live only in water and damp places
most important type of algae for this class and why
red algae (agar source) because it is the solidifying agent for our medium in lab
