Chapter 5 Eucaryotic Cells and Microorganisms |
|
|
Basidiospores
|
a sexual spore that arises from a basidium. Found in basidiomycota fungi
|
|
|
basidium
|
a reproductive cell created when the swollen terminal cell of a hypha develops filaments (sterigmata) that that form spores.
|
|
|
conidia
|
asexual fungal spores shed as free units from the tips of fertile hyphae
|
|
|
cyst
|
The resistant, dormant, but infectious form of portozoans, Can be important in spread of infectious agents such as Entamoeba histolytica and Giardia lamblia
|
|
|
Endoplamic reticulum
|
Two types
Rough endoplasmic reticulum (RER) Smooth endoplasmic reticulum (SER) Nuclear envelope form membrane for the ER |
|
|
glycocalyx
|
a filamentous network of carbohydrate-rich molecules that coats cells
|
|
|
golgi apparatus
|
Closely associated with the ER
Site for protein modification Cisternae – noncontinuous membrane network Condensing vesicles |
|
|
Hypae
|
Tubular threads that makeup filamentous fungi (molds). this web of branched andinter twining fiber is called a mycelium
|
|
|
Mitochondria
|
Site of energy generation
Cristae-folds of the inner membrane Matrix-consist of ribosomes, DNA, and enzymes |
|
|
mitosis
|
Somatic cell division that preserves the somatic chromosome number
|
|
|
mycelium H
|
Mycelium the filamentous mass that makes up a mold. composed of hyphae
|
|
|
Nucleolus
|
site for RNA synthesis a granular mass, it is in the nucleus
|
|
|
RER
|
Coated with ribosomes
Site of proteins synthesis Transport material from the nucleus to the cytoplasm and cell membrane Transitional vesicles |
|
|
organelles
|
cooperate in protein synthesis and transport, it is bounded by a membrane and specialized in function
|
|
|
Parasites
|
an organism that lives on or w/i another organism (the host) from which it obtains nutrients & enjoys protection. it produces some degree of harm to host
|
|
|
Plankton
|
Minute animals (zooplankton) or plants (phytoplankton) that float & drift in the limnetic zone of bodies of water.
|
|
|
Pseudophyphae
|
a chain of easily separated, spherical to sausage-shaped yeast cells partitioned by constrictions rather than by septa
|
|
|
Sabrobes
|
a microbe that decomposes organic remains from dead organisms, also know as a saprophyte or saprotroph
|
|
|
sphores
|
a differentiated, specialized cell form that can be used for dissemination, for survival in times of adverse conditions, and/or for reproduction, spores r usually unicellular & may develop into gametes or vegetative organisms
|
|
|
substates
|
the specific molecule upon which an enzyme acts
|
|
|
identify the elements of eucaryotic cell structure
|
Appendages - Flagella, Cilia,
Glycocalyx Cell wall Cell membrane |
|
|
Describe the essential element of the major organelles
|
External and internal structures are more complex than procaryotes
IDK |
|
|
Identify where eucaryotic cells are found
|
in fungi, protozoa, algae, plants, and animals,
|
|
|
Describe the structure & life cycle of fungi
|
fungi feed on organic substrates, have cell walls, reproduce asexually & sexually by spores, exist in macro& microscopic forms, free loving decomposers that r beneficial & sm cause infections
|
|
|
Identify types of fungi
|
microscopic are yeasts & molds. approx 100,000 species , macroscopic mushrooms puffballs gill fungi
|
|
|
discuss the key elements of algae
|
algae occur in unicellular, colonial & filamentous forms, the larger forms can possess tissue & simple organs. a most noticeable organelle would be chloroplasts
|
|
|
Mycoses
|
fungal infections in animals & thousands of species r important plant pathogens
|
|
|
sporangiosphores
|
are formed by successive cleavages within a saclike head called asporangium, which is attached to a stalk, they are released when the sporangium ruptures
|
|
|
discuss the key elements of Protozoa
|
protozoa = first animals, single cells hv major eucaryotic organelles excpt chloroplasts, highly specialized for feeding, reproduction, and locomotions
|
|
|
More key elements of Algae
|
Photosynthetic
Inhabitants of fresh and marine waters Most are not considered human pathogens Pathogens produce toxins (ex. red tide) Unique morphology enables identification |
|
|
More key elements of Protozoa
|
Complex structure and function
Ectoplasm and endoplasm Pseudopods, flagella, cilia Inhabitants of fresh water and soil. Heterotrophs Reproduction (asexual. Trophozoite or Encystment |
|
|
Discuss subgroups of Protozoa
|
Mastigophora (flagellated)
Sarcodina (Amoebas) Ciliophora (ciliated) Apicomplexa (sporozoa) pg 143 144 |
|
|
Discuss the infective helminth
|
The most developed organs are those of the reproductive tract, in some they are no more than flattened sacs filled w/ovaries testes & eggs
