BRE is the world’s leading, multi-disciplinary building science organisation: an innovative group of researchers, scientists, engineers and technicians who share a common goal – to make the built environment better for all.
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.
ALGA empowers our local government auditing community through excellence in advocacy, education, communication, and collaboration to protect and enhance the public good while embracing diversity, equity, and inclusiveness.
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.
AlgaeBase is a global algal database of taxonomic, nomenclatural and distributional information. 183,750 species and infraspecific names, 24,082 images, 76,407 bibliographic items and 618,193 distributional records.
Algae (singular alga) are a large and diverse group of photosynthetic, eukaryotic, plant -like organisms that use chlorophyll in capturing light energy, but lack characteristic plant structures such as leaves, roots, flowers, vascular tissue, and seeds.
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.
