Chrysolaminarin
|
bacilliophyta: carbohydrate stored as starch
|
|
|
Antheridium
|
a gametangium that produces sperm
|
|
|
Archegonium
|
a gametangium that produces eggs
|
|
|
Carpospore
|
a diploid spore developed from the fertilized carpogonium in the red algae
|
|
|
Carposporophyte
|
created when a spermatium united with an egg to produce a zygote; one of two sporophyte states in Polysiphonia; remains in the carpogonium and produces carpospores by mitosis
|
|
|
Centric
|
Chrysophyta: a type of diatom that is circular in outline.
|
|
|
epitheca
|
the upper (larger) half of the frustule of a diatom
|
|
|
Frustule
|
bacillariophyta:the silica cell wall of diatoms
|
|
|
Fucoxanthin
|
brown accessory pigment characteristic of Stramenopila
|
|
|
Gametangium
|
a structure that produces gametes
|
|
|
Gametophyte
|
a plant or a life cycle phase that produces gametes
|
|
|
Heterocyst
|
Cyanobacteria: a transparent, thick-walled cell that is involved in nitrogen fixation
|
|
|
Heterogametic
|
The gender which has two different sex chromosomes.
|
|
|
Heteromorphic
|
the sporophyte and the gametophyte phases of a species having a sporic life cycle (alternation of generations) have different morphologies
|
|
|
Holdfast
|
the structure by which kelp are attached to rocks or other substrate
|
|
|
Hypotheca
|
the lower (smaller) half of the frustule of diatoms
|
|
|
Isogamous
|
the gametes of an organism are all alike, such that "male" and "female" cannot be distinguished; in this case mating strains are usually desginated "+" and "-"
|
|
|
Isomorphic
|
The sporophyte and the gametophyte phases of a species having a sporic life cycle (alternation of generations) have identical morphologies
|
|
|
Meiospore
|
Cell that is one of the products of meiosis in plants; they are thus haploid, and give rise to a haploid daughter cell(s) or a haploid individual.
|
|
|
Merozoites
|
a daughter cell of a protozoan parasite. Merozoites are the result of asexual reproduction; formed during the asexual division of the schizont. Merozoites are released and invade other cells.
