QuestionAnswer
largest variety among the 6 kingdoms of organisms Kingdom Protista
they have Unicellular and multicellular organisms Kingdom Protista
cant be classified as animal plants or fungi (outcast) eukaryotes
Lack specialized features they characterize the 3 other multicellular kingdoms Don’t fit any where else Kingdom Protista
(some protist ) some resemble plants photosynthetic
some just food like animal ingest food
absorb their food fungi
some have this it is used for motion Flagella or cilia
Found almost everywhere there is water protists
some live inside and cause harm parasites
any of them have _____________for monitoring and responding to stimuli in there environment Mechanisms
small organelle that contains light sensitive pigments that detects changes in the quality and intensity of light eyespots
many reproduce only asexually by mitosis some use meiosis and sexually re only in times of environmental stress and other reproduce sexually most of the time sexual reproduction
some are simple and some are very complex multicellularity
heterotrophic protists Protozoa
photosynthetic protists Algae
belong to the phylum Rhizopoda Amoebas
flexing cytoplasmic extensions Bulges from the cell surface starching outward and anchoes itself to the near by surface the cytoplasm from the rest of the amoebas then floats into the cytoplonium Pseudopodia
used for movement pseudopodia
phylum Bacillariophyta Diatoms
Photosynthetic Unicellular Diatoms
Unique double shells made of silica Diatoms
abundant oceans and lakes and they are important producers in the food chain environment
Strict phototrophs Algae
Some are Unicellular and some are multicellular algae
Distinguished by the photosynthetic pigment they contain algae
green some are large multicellular marine organisms phylum Chlorophyta
red multicellular organisms found in warm ocean waters phylum Rhodophyta
brown mostly found in the marine environments (kelp) phylum Phaeophyt
phylum Dinoflagellates Flagellates
use for movement most have 2 flagella
Flagellates environment marine often components of plankton
phylum Ciliophora Paramecium
large numbers of cilia usually arranged in long rows along the body or spirals around it Cilia
Heterotrophs with restricted mobility Protistan molds
Not fungi there cell wall are made of carbohydrates where fungi's have cell wall made of chitin Protistan molds
group of weird organisms that streem along as plasmosium Myxomycota
mass of cytoplasm that looks like oozing slime Plasmodium
Method of food gathering as they move they eat bacteria and other organic materials Plasmodium
phylum Sporozoa Sporozoans
don’t move Non-motile
Spore forming Sporozoans
Unicellular parasite Sporozoans
method of infection (Sporozoans) infect animals with small spores that are transmitted from host to host
protest in there digestive track which enables them to digest the cellulose in the hay and the grass they eat cattle
make much of the plant in the ocean and they help support the food chain plankton
single largest Photosynthesizers on the plant plankton
they recycle many import and chemicals such as nitrogen carbon and phosphorus Detritivores
most deadly Malaria
chills fever sweating confusion and thirst malaria
cur for malaria chemical derived from the bark of the cinchona tree in south America Quinine
spray insecticide we decrees the mosquito breeding places and can introduced animals that will eat the mosquitos larva Methods of controlling mosquito population
