| Describe the classification of fungi with emphasis on the medically important species. | Zygomycota—obligate parasites of insects or other fungi
Ascomycota—includes Penicillium, which produces the antibiotic penicillin
Basidiomycota—includes mushrooms that can produce toxins, yeasts that can cause meningitis
Deuteromycota—referred to as im

||||
| Describe the general characteristics of algae and their possible life cycles. | Algae are photosynthetic and are widespread in fresh and marine waters where they play an essential role in the aquatic food chain; also found in soil, on rocks, and on plants. Algae are capable of both sexual and asexual reproduction.

Trypanosoma—infects blood
Amoeba—infects central nervous system
Entamoeba—infects intestines, liver
Toxoplasma—CNS
Cyclospora—intestine
Cryptosporidium—intestine
Leishmania—infects skin
Trichomonas—urogenital tract

| Describe the fundamental difference between cellular and plasmodial slime molds. | Cellular slime molds are eukaryotic cells with one nucleus (resembling an amoeba).
Plasmodial slime molds are masses of protoplasm containing many nuclei.
🗑
|
||||
| describe the basic structure of cestodes (tapeworms) and their life cycle. | Tapeworms have a scolex (head), a neck, and one or more proglottids (body segments). The worm attaches to the host intestine. The cells of the neck form new segments that elongate the worm. Mature proglottids contain eggs and are released from the end of

| malaria | endemic in countries in a belt area roughly about the equator in tropical and subtropical climates. A disease associated with poverty, is also a hindrance to economic progress, particularly where it is endemic in developing countries.
🗑
|
||||
| molds | rapidly growing, asexually reproducing fungi that grow on a variety of substances. They are characterized by the development of hyphae, which results in colony characteristics that can be used for identification purposes.
🗑
|
||||
| ascomycota | the primary fungi causing food spoilage. This group also includes plant pathogens, bot producing a negative impact on the economy. However, many of the ascomycota are beneficial and probably the best known fungus in this category is penicillin, the mold
🗑
|
||||
| algae | microscopic, photosynthetic organisms that are widespread in fresh and marine waters. They are a main component in plankton, a community of free-floating microscopic organisms that play an essential role in the aquatic food chain.
🗑
|
||||
| dinoflagellates | medical concerns involving algae are due primarily to food poisoning caused by toxins of marine algae such as dinoflagellates. Overgrowth of these motile organisms during certain times of the year causes "red tides".
🗑
|

| protozoans | a group of microorganisms that are defined by three common characteristics: (1) they are eukaryotes; (2) they are unicellular; and (3) they lack a cell wall. Many protozoans are free-living organisms where as others are potential parasites of humans and o
