Synapomorphy
A shared characteristic inherited from a common ancestor.
Cilia/Ciliate
External covering of fine hairs used to propel protozoan ciliate through water.
Flagellum
A long cellular appendage specialized for locomotion. The flagella of prokaryotes and eukaryotes differ in both structure and function.
Vacuole
A space surrounded by membrane filled with digestive enzymes. Amoeba use them to keep from overfilling with water and bursting.
Micro/Macronucleus
Paramecium have a larger and smaller nucleus. Each contains the DNA of the organism. The micro are important for generating genetic diversity by conjugation.
Antigenic Variation
a mechanism whereby parasites, such as trypanosomes, plasmodia, and Borrelia, are enabled to escape immune surveillance of a host by modifying or completely altering their surface antigens.
Psuedopod
Amoebas extrude regions of their cytoplasm to move around.
Fission
In cellular bodies, when a cell essentially tears itself in two, a form of asexual reproduction.
Conjugation
n prokaryotes, the direct transfer of DNA between two cells that are temporarily joined. In ciliates, a sexual process in which two cells exchange haploid micronuclei.
Merozoites
Stage of Malaria that takes residence in the red blood cells of the host, where they feed on hemoglobin. The popping of infected cells cause the fever associated with malaria.
Gametocytes
Some merozoites become these, and reproduce sexually when sucked out of the blood by another mosquito.
Plasmodial
Stage in slime molds where it is extemsive, slimy, shapeless mass of cytoplasm (the plasmodium).
Sporangial
Reproductive or fruiting body stage of the slime mold, is a fine, net-like structurethat forms an upright sporangium
Fruiting body
The upright sporangium of the fungi that holds the haploid spores.
Cytoplasm
The entire contents of the cell, exclusive of the nucleus, and bounded by the plasma membrane.
Saprophytic
Organism that obtains nourishment through absorption.
Lichen
The symbiotic collective formed by the mutualistic association between a fungus and a photosynthetic alga or cyanobacterium
Mycorrizhae
Mutualistic associations of plant roots and fungi. Can be endo-mycorrizhae or ecto-mycorrizhae.
Hyphae
Filaments that collectively makes up the body of a fungus
Mycelia
The densely branched network of hyphae in a fungus
D. Ascomycota
Large group of terrestrial and aquatic fungi. Over 30000 species identified to date.
D. Ascomycota

Ascospores -> Ascus -> Ascocarp
Spores of the Ascomycota produced inside the ascus where meiosis occurs. The ascus(asci) is located inside a hyphal structure called an ascocarp.
D. Basidiomycota

Basidiospores -> Basidium -> Basidiocarp
Terrestrial fungi. Mushrooms and toadstools are basidiomycota.
3 parts of a mushroom
1. Lamellae

2. Pilleus

3. Stipe
Describe the moss lifecycle.
Duh
Describe the fern lifecycle.
Duh.
