| algae | <botany> A nontaxonomic term used to group several phyla of the lower plants, including the Rhodophyta (red algae), Chlorophyta (green algae), Phaeophyta (brown algae) and Chrysophyta (diatoms). Many algae are unicellular or consist of simple undifferentiated colonies, but red and brown algae are complex multicellular organisms, familiar to most people as seaweeds. Blue green algae are a totally separate group of prokaryotes, more correctly known as Cyanophyta or Cyanobacteria. (18 Nov 1997) |

| algae and fungi | Algae represent a group of spore-propagating plants, unicellular or undifferentiated into root, stem, and leaf. They include seaweed and many unicellular fresh water plants, most of which contain chlorophyll. They account for about 90% of the earth's photosynthetic activity. Fungi are eukaryotic, heterotrophic organisms that live as saprobes or parasites and include mushrooms, yeasts, smuts, molds, etc. They lack chlorophyll. (12 Dec 1998) |
| algae, brown | Predominantly marine algae of the division phaeophyta, having chromatophores containing carotenoid pigments. Genera include ascophyllum, fucus, eisenia, petalonia, ectocarpus. (12 Dec 1998) |
| algae, green | Algae of the division chlorophyta, in which the green pigment of chlorophyll is not masked by other pigments. Classes include charophyceae, bryopsidophyceae, conjugatophyceae, oedogoniophyceae, chlorophyceae, and prasinophyceae. Common genera are acetabularia, chlamydomonas, chlorella, nitella, prototheca, scenedesmus, spirogyra, and volvox. (12 Dec 1998) |
| algae, red | Algae of the division rhodophyta, in which the pigment is predominantly red; common genera are gelidium, gracilaria, and polysiphonia. (12 Dec 1998) |
| blue-green algae | The former name for the blue-green bacteria, now classified as Cyanobacteria. A group of prokaryotes. Synonym: Cyanobacteria. (05 May 2002) |
|---|---|
| Characean algae | <organism> Class of filamentous green algae exemplified by the genus Chara, in which the mitotic spindle is not surrounded by a nuclear envelope. Probably the closest relatives, among the algae, to higher plants. The giant internodal cells (up to 5cm long) exhibit dramatic cyclosis and have been much used for studies on ion transport and cytoplasmic streaming. (21 May 1997) |
| Green algae | <botany> Division of algae containing photosynthetic pigments similar to those in higher plants and having a green colour. Includes unicellular forms, filaments and leaf like thalluses (e.g. Ulva). Some members form coenobia and the Characean algae have branched filaments. (18 Nov 1997) |
| symbiotic algae | <plant biology> Algae (often Chlorella spp) that live intracellularly in animal cells (e.g. Endoderm of Hydra viridis). The relationship is complex, because lysosomes do not fuse with the vacuoles containing the algae and the growth rates of both cells are regulated to maintain the symbiosis. There is considerable strain specificity. The term is imprecise, since there are many other symbiotic algae (as in lichens) where the relationship is different. (19 Jan 1998) |

| algae |
The algae (singular alga) comprise several different groups of living organisms usually found in wet places or water bodies and that capture light energy through photosynthesis, converting inorganic substances into simple sugars with the captured energy. Algae were traditionally regarded as simple plants, and some are closely related to the higher plants. ...

| algae |
Chiefly aquatic, eucaryotic one-celled or multicellular plants without true stems, roots and leaves, that are typically autotrophic, photosynthetic, and contain chlorophyll. Algae are not typically found in groundwater. They also may be attached to structures, rocks or other submerged surfaces. They are food for fish and small aquatic animals. Excess algal growths can impart tastes and odors to potable water. Algae produce oxygen during sunlight hours and use oxygen during the night hours. ...

| algae |
(sing. = ALGA) - unicellular or simple multicellular organisms with chlorophyll, lacking the multicellular sex organs typical of plants. Comprise several eukaryotic chromistan phyla (some, like the kelps, large and plant-like), plus the prokaryotic `blue-green algae' (Cyanobacteria).

| algae |
Single-celled organisms that live in both fresh and salt water and contain chlorophyll, the substance plants use to make food from sunlight. Algae is the plural; alga is the singular.
