Eukaryotic Diversity Flashcards
What are algae?
Can be single or multicellular, most are photosynthetic.
What are Phaephyta?
Brown algae; multicellular, macroscopic, and produce algin.
What are diatoms?
Unicellular or filamentous, store oil, and produce domoic acid.
What characterizes Rhodophyta?
Red algae; multicellular, have structures that branch out, agar, and some are toxic.
What are Chlorophyta?
Green algae; unicellular or multicellular, cellulose wall, chlorophyll, stores starch.
What are dinoflagellates?
Usually marine, unicellular, can cause neurotoxins, has flagella around the middle.
What are oomycota?
Water molds, not photosynthetic, can produce zoospores which can be parasitic.
What is the significance of algae in the ecosystem?
Fixes CO2 in atmosphere and produces 80% of Earth’s oxygen.
What are the stages of protists or protozoa?
Can have cyst or trophozoite stages.
What is plankton?
Includes zooplankton and phytoplankton; live in water.
What is biofilm?
A community of microorganisms that adhere to surfaces.
What are common structures used by protists for movement?
Cilia, flagella, and pseudopodia.
What is lichen?
A combination of algae/cyanobacteria + fungus.
What are the types of lichen?
- Crustose - crusty appearance
- Foliose - leaf-like lobes
- Fruticose - rounded structures and branched.
What is a key component of fungal cell walls?
Chitin.
How can fungi reproduce sexually?
Through cross or self-fertilization.
How can fungi reproduce asexually?
Through mitosis or fragmentation.
What are characteristics of yeast?
Unicellular, budding yeasts reproduce asexually.
What are molds?
Multicellular fungi that have hyphae.
What are helminths?
Parasitic worms including roundworms (nematoda) and flatworms (platyhelminthes).
