[WordNet 1.5] |
Algae (gcide) | Alga \Al"ga\, n.; pl. Alg[ae] or algae. [L., seaweed.]
(Bot.)
A kind of seaweed; pl. the class of cellular cryptogamic
plants which includes the black, red, and green seaweeds, as
kelp, dulse, sea lettuce, also marine and fresh water
conferv[ae], etc. The algae are primitive
chlorophyll-containing mainly aquatic eukaryotic organisms
lacking true stems and roots and leaves.

Algae (gcide) | Cryptogamia \Cryp`to*ga"mi*a\ (kr?p`t?-g?"m?-?), n.; pl.
Cryptogami[ae] (-?). [NL., fr. Gr. krypto`s hidden, secret
+ ga`mos marriage.] (Bot.)
The series or division of flowerless plants, or those never
having true stamens and pistils, but propagated by spores of
various kinds.
[1913 Webster]
Note: The subdivisions have been variously arranged. The
following arrangement recognizes four classes: -- I.
{Pteridophyta, or Vascular Acrogens.} These include
Ferns, Equiseta or Scouring rushes, Lycopodiace[ae]
or Club mosses, Selaginelle[ae], and several other
smaller orders. Here belonged also the extinct coal
plants called Lepidodendron, Sigillaria, and
Calamites. II. {Bryophita, or Cellular Acrogens}.
These include Musci, or Mosses, Hepatic[ae], or
Scale mosses and Liverworts, and possibly
Charace[ae], the Stoneworts. III. {Alg[ae]}, which
are divided into Floride[ae], the Red Seaweeds, and
the orders Dictyote[ae], Oospore[ae],
Zoospore[ae], Conjugat[ae], Diatomace[ae], and
Cryptophyce[ae]. IV. {Fungi}. The molds, mildews,
mushrooms, puffballs, etc., which are variously grouped
into several subclasses and many orders. The Lichenes
or Lichens are now considered to be of a mixed nature,
each plant partly a Fungus and partly an Alga.

blue-green algae (gcide) | cyanobacterium \cyanobacterium\ pl. cyanobacteria
\cyanobacteria\ [from the pigment phycocyanin.]
any of a group of photosynthetic autotrophic prokaryotic
microorganisms possessing characteristics of both bacteria
and plants. When classed as bacteria, they are assigned to
the Cyanobacteria; when classed as plants, they are assigned
to the Cyanophyta. They were earlier named {blue-green
algae}, a term less used now in technical discussions. Since
the chlorophyll within the cyanobacteria is diffused
throughout the cell, rather than being contained in
chloroplasts, they are no longer thought of as true plants.
[PJC]blue-green alga \blue"-green al"ga\ pl. blue"-green al"gae
[from the color and resemblance to algae.]
any of a group of photosynthetic microorganisms possessing
characteristics of both bacteria and plants. When classed as
bacteria, they are assigned to the Cyanobacteria; when
classed as plants, they are assigned to the Cyanophyta. They
are now known to be prokaryotic, and are usually called
cyanobacteria in technical contexts. See cyanobacterium.
