What are zygomycetes?
Conjugational fungi
How do protists reproduce?
Asexually via fission
Sexually via meiosis
How do protists get energy?
Cellular respiration
True or false: Protists lack the biochemical diversity of prokaryotes but contain drastic heterophotogenic diversity?
False: morphological diversity
What kind of environment are protists usually found in?
How are Protists classified?
Algae and dinoflagellates
What can cause "red tides"
What are chrysophytes and where are they located?
Golden algae and diatoms
Ponds and temperate lakes as plankton
Name four aspects of euglenophytes:
1. contain an "eye spot"
2. in the dark, they live as heterotrophs
3. when light is available they photosynthesize
4. all reproduce asexually
Name an aspect of Phaeophytes
Brown algae are multicellular and include the Giant Kelps
Name two aspects of Rhodophytes
1. the phaeophytes and the rhodophytes make up most of the seaweeds
2. all reproduce sexually
Name two aspects of chlorophytes:
1. more like plants than any other protists
2. thought to be the land plant's evolutionary precursor
True or false: Protozoa are heterotrophic?
Name two aspects of the rhizopoda (ameboa)
1. all reproduce via simple cell division
2. all ameboa change shape by pseudopodia
Name three aspects of sporozoans:
1. all are parasites
2. very complex life cycles, involving multiple hosts
3. PLASMODIA causes malaria
Name two aspects of ciliophora:
1. includs about 8,000 species of free-living single celled heterotrophs that live in fresh and salt water
2. best known as paramecium
Paramecium are better known as what?
Name two aspects of fungus-like protists
1. they flourish as ameoba
2. when food is scarce, they form a multicellular structure that can migrate to food and light
What is plasmodial slime mold?
It develops as a plasmodium (mass of cytoplasm) and is similar to cellular slime mold
True or false: in dikaryotic fungi the nuclei lie in a common cytoplasm
False: coenocytic
Name several aspects of oomycota
1. most nearly resembles true fungi
2. are either parasitic or saprophytic
What are most fungi composed of?
Masses of thread like filaments
What are these thread-like filaments called?
True or false: Hyphae contain only one nuclei each
False: they contain many nuclei
True or false: In coenocytic walls called septa separate the 2 nuclei within each filament?
Define myceluim
The mass that hyphae grow, branch and intertwine
How do fungi obtain food?
By infiltrating the bodies of organisms (or debris) with long, thin hyphae
How do fungi reproduce?
Both asexually and sexually
Name two aspects of zygomycetes
1. The hyphae are coenocytic
2. include bread molds
What are protists?
Eukaryotic organisms that do not belong to any of the other eukaryotic kingdoms
Protists include:
Some fungus-like forms
