Most of the organisms called 'seaweeds' are brown algae, although some are red algae and a few are green algae. (geneseo.edu)
Like most (but not all) brown algae, Fucus is a large, multicellular organism that well-adapted to life in intertidal and shallow coastal waters, most commonly in relatively cool waters. (geneseo.edu)
The brown algae are a small group of eukaryotes who traditionally were placed in their own phylum, the Phaeophyta, sometimes along with two groups of primarily unicellular algae, the golden algae and the yellow-green algae, based on similarities in pigmentation and other factors. (geneseo.edu)
Brown algae have transport systems that allow photosynthate from the blade to be distributed throughout the plant. (geneseo.edu)
Most brown algae are sexual and exhibit alternation of generations. (geneseo.edu)
The 'dominant' (i.e. larger and more visible) stage is usually the sporophyte (diploid) stage but there are some brown algae that show isomorphic alternation of generations (the sporophyte and gametophyte look identical) and a few where the gametophyte stage is dominant. (geneseo.edu)
In Fucus the gametes are distinct from one another (egg, sperm) and in some brown algae they all look the same (isogametes). (geneseo.edu)
Within the brown algae flagellated cells are common and include sperm, isogametes and zoospores, which are mobile cells that can attach to a substrate and grow into a new organism. (geneseo.edu)
The brown algae produce a distinct form of a carbohydrate storage polysaccharide called laminaran, made up of glucose units connected by a beta 1-3 linkage, rather than the alpha , 1-4 linkage found in starch. (geneseo.edu)

Specimens were documented via: (1) direct observation in the field (mainly snorkeling, but also SCUBA diving), or (2) substrate collection (primarily various species of algae and hydroids). (biomedcentral.com)

Photosynthesis3
Plants, algae and a few other organisms rely on a process known as photosynthesis to fuel themselves, as they can harness cellular structures called chloroplasts to convert light into usable energy. (elifesciences.org)
To investigate this question, Havurinne and Tyystjärvi compared photosynthesis in sea slugs and the algae they eat. (elifesciences.org)
His Algae research incorporates themes from Archaeplastida, Chloroplast, Cyanophora paradoxa and Evolution of photosynthesis. (research.com)

Slug1
The sea slug Elysia timida , however, can steal whole chloroplasts from the cells of the algae it consumes: the stolen structures then become part of the cells in the gut of the slug, allowing the animal to gain energy from sunlight. (elifesciences.org)
Diatoms2
A number of organisms under consideration here (e.g., many bacteria, archaea, diatoms, dinoflagellates, and many green algae) are unicellular and, while their devel opment is quite different than for multicellular organisms, they do change over time and show definite patterns of development. (geneseo.edu)

This effect can be demonstrated by shining a ray of blue light on a stem in the dark and extinguishing it some time later, forming a transient green band. (wikipedia.org)
