What are Fungi?
Eukaryotic heterotrophs that can be multi-cellular or unicellular with cell walls composed of Chitin and beta-glucans,
What are unicellular fungi called
Yeasts
what are multicellular fungi called
molds
how do yeasts reproduce
asexually by budding
how do molds reproduce
by sexual and asexual spores
which type of miccrobe causes: ringworm yeast infections (candidiasis) histoplasmosis coccidioidomycosis cryptococcosis pneumocystis pneumonia
fungi
What are protozoa
single-celled eukaryotes
where do you find protozoa
typically living freely in water, but some live inside animal hosts
how do protozoa reproduce
most often asexually
how are protozoa classified and what are the three classes of protozoa
they are classified by means of locomotion
- pseudopodia
- cilia
- flagella
- Non-motile
what are pseudopodia
cytoplasmic extensions that flow in the direction of travel
what are cilia
many short hair-like protrusions that propel protozoa
what are flagella
few, long, and whip like extensions that spin and move protozoa
What are algae
photosynthetic microbes with simple reproductive structures that can be either unicellular or multi-cellular.
are algae pathogenic
No, with one exception, their role in red tides and shellfish poisoning
What are prokaryotes
small unicellular and non-eukaryotic microbes
where do you find prokaryotes
any where there is moisture, even extreme environments
how do prokaryotes reproduce
asexually
what are the two kinds of prokaryotes
bacteria and archaea
What is found in bacterial cell walls, that helps distinguish them from other cells
peptidoglycan
are any known diseases caused by archaea
no
