Why is fungi in it's own Kingdom?
Structure: chitin instead of cellulose, Reproduction method, and How nutrients are obtained: saprophytic
Why are Fungi not plants?
they don't use photosynthesis, structures: chitin vs cellulose
Saprophytes: heterotrophic bacteria that feed on dead and decaying material, let out enzymes and then absorb through cell wall
based on structure and Form of sexual reproduction
Parastism: good for organism; bad for host, Mutualism: good for both, Commensalism: good for organism; doesn't effect host
association between a fungus and plant roots.
represents symbiotic relationships between a fungus and photosynthetic partner.
Why fungi imperfecti
Fungi doesn't have a sexual stage and being reclassified
Uniqueness of Euglena
can be heterotrophic during the night when other organisms are available to eat; photosynthetic when no food and during the day.
Paramecium eating/Cytoplasmic streaming
Cilia sweep food down groove to mouth and then the gullet forms a good vacuole
Classification of Algae
color, type of chlorophyll, form of food storage, cell wall composition, body type (thallus)
Protists vs plant, animals, fungi (difference)
lack tissue differation/specialization - sexual and/or asexual
Protists vs plant, animals, fungi (similarities)
Algea vs. Protists
they use photosynthesis
Algae former kingdom and why not
K. Plantea - lack tissue differation - no plants/leaves - different reproduction structors
Fungus-like Protists vs. other protists
unique life cycle
Algae Body Types
spirogyra: filamentous, Volvox: colonial algae, Ulva: multicellular algae, Chlamydomonas: unicellular algae
pseudopodia: false feet, movement, eating; amoeba
flagellum for movement; tryanosoma
cilia: how they eat and movement; Paramecium
cap, gills, stalk
Includes penicillium and rihizopus stolonifer
filaments of fungus
study of fungi
separating 2 chambers
filaments with out internal cross wall
cell walls of hyphae
cup like structor
above ground structor
cup like sex reproductive structor
body proportion of algae
part of an thallus that anchors its to a substrate (rootlike)
stem like proportion of algae
leaf like region; capture sunlight
Alternation of generations
Ulva sexual reproduction cycle; between haploid and diploid
in times of stress, cells reproduce
dinoflagellate population explode; turn water red
Evolutionary advantage for algae to reproduce asexually and sexually?
No matter what it can reproduce even with out a mate. Genetic variation; for for environment.
Characteristics of protozoans
single celled, most move independently, most heterotrophic, all can asexual, some sexual
controls cell asexual (binary vision)
genetic exchange (conjugation)
