Most algae are single-celled organisms without roots, leaves, or stems. Most are photoautotrophs and the main primary producers of aquatic ecosystems, although some are mixotrophs that derive metabolic energy both from internal photosynthesis and from foraging external nutrients.
In many red algae (e.g., Palmaria), numerous adjacent filaments joined laterally create the gross morphological form of the alga. Parenchymatous (tissuelike) forms, such as the giant kelp (Macrocystis), can measure many metres in length.
Algae are primarily aquatic, photosynthetic organisms that are often simple in structure and range from unicellular microalgae, like diatoms, to multicellular forms, such as giant kelp.
The meaning of ALGA is any of a diverse group of chiefly photosynthetic and aquatic plantlike organisms that range from unicellular to large multicellular forms, are typically classified as protists, and include the green, yellow-green, brown, golden-brown, and red algae in the eukaryotes and especially formerly the cyanobacteria in the ...
Blue-green algae are common in soil, in both salt and fresh water, and can grow over a wide range of temperatures. They have been found to form mats in Antarctic lakes under several meters of ice and are responsible for the beautiful colors of the hot springs at Yellowstone and elsewhere.
But unlike plants, algae have no roots, leaves, or flowers. Our cover illustrates some of the incredible stories of algae. The left side of the cover shows one of the most amazing things about certain algae: they glow in the dark.
