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 confervæ, etc. The algae are primitive chlorophyll-containing mainly aquatic eukaryotic organisms lacking true stems and roots and leaves.
a plant or plantlike organism; very small green and red algae grow on the skin of manatees; when manatees rub against objects or other manatees, scar like patterns appear where the algae are removed.
single celled green plants usually growing in water; often in long chain, visible to naked eye.
(al´ gah) (plural: algae) [L.: seaweed] • Any one of a wide diversity of protists belonging to the phyla Pyrrophyta, Chrysophyta, Phaeophyta, Rhodophyta, and Chlorophyta.
A chiefly aquatic plantlike organism that uses photosynthesis to produce its own food. Unlike plants, algae do not have true roots, stems, or leaves.
Informal term used to describe a wide range of photosynthetic organisms, either procaryotic or eucaryotic. Eucaryotic examples include Nitella, Volvox, and Fucus.
Any of diverse types of eukaryotic photoautotrophic single-celled protists, such as phytoplankton or many-celled seaweeds
a member of one of the protist biological Kingdoms
a photosynthetic eukaryote that is usually found in aquatic ecosystems
aquatic plants of fresh or sea water from microscopic in size to 200 feet in length; simple, photosynthetic plants.
(pl. algae) A general name for the single-celled plant plankton, seaweed's, and their freshwater allies.
(plural = algae): the common name for simple plants which do not have specialised parts such as roots or leaves. They do not have vascular systems, so most are found living in water. Algae can range from single cells (e.g. Euglena) to plants of several metres in length (e.g. kelp).
a photosynthetic, plant-like protist.
A general name for the single-celled, predominantly aquatic, organisms that photosynthesize but lack the specialized reproductive structures of plants. Algae lack true roots, stems, and leaves.
An aquatic single celled plant like organism.
