Protist Characteristics
Short, hair-like extensions used for cell movement.
What are cilia?
Group of protists which possess flagella with fine hairs
What is stramenopila?
Chains of cells that are separated by cross walls.
What are septate hyphae?
The symbiotic relationship where both organisms benefit
What is mutualism?
The theory which explains the presence of DNA, ribosomes and a double membrane in the mitochondria and chloroplasts.
What is endosymbiosis theory?
What are osmotrophs?
Unicellular and colonial phagotrophs that are considered the closest living relative to animals.
What are chaonoflagellates?
A fungal organism which possesses 2 nuclei.
What is a dikaryotic?
An organism which causes disease only when the host is otherwise immunocompromised
What is an opportunistic pathogen?
A type of algae which is considered to be the closest living ancestor to land plants
What is Chlorophyta?
Long, tail like extensions used for movement
What are flagella?
Unicellular algae which have 2-part shells
What are diatoms?
A woven mass of fungal hyphae.
What is a mycelium?
A symbiotic relationship between a fungi and a unicellular photosynthetic organism such as algae or cyanobacteria
What is a lichen?
Organism which is composed of many cells working together, each of which can survive on their own.
What are colonial organisms?
Form of protist reproduction which involves several rounds of nuclear division followed by several rounds of cytokinesis to produce many, small daughter cells from a single parent cell.
What is schizogony?
Multicellular red algae which provide food, oxygen and habitat
What are rhodophytes?
The form of nutrition which is used by fungi
What is saprophytic nutrition?
The symbiotic relationship between a fungal organism and the roots of plants
What are mycorrhizae?
Form of fungal reproduction where a portion of the hyphae breaks off to establish in a new location
What is fragmentation?
Animal-like protists which engulf food to break it down internally.
What are phagotrophs?
Filamentous protists which were previously thought of as fungi and function as important pathogens and decomposers
What are oomycetes/water molds?
The material found in the cell walls of fungi.
What is chitin?
Fungi which live in intracellular spaces inside plants
What are endophytes?
Multicellular, red algae which are ecologically significant as producers of food and oxygen as well as a source of habitat for other aquatic organisms
What are Rhodophyta?
