The brown algae comprise the class Phaeophyceae, golden-brown algae that range from small filamentous forms to large, complex seaweeds. Of the estimated 1,836 species in approximately 285 genera, fewer than 1% are found in freshwater habitats. Phaeophyta ( Brown Algae ) by jena lenning on Prezi Classification Characteristics Natural & Human uses ? Amazingly algae is being tested as a bio-fuel and as a bio-diesel by extracting oil from the algae habitat Brown algae are eaten by herbivorous organisms such as fish, gastropods and sea urchins. Benthic (bottom-dwelling) Golden-Brown Algae The golden-brown algae include both the chrysophytes and the synurophytes. The motile chrysophytes are sometimes referred to as the chrysomonads. Both the chrysophytes and synurophytes are most abundant and diverse in freshwaters of neutral or slightly acidic pH with low conductivity, alkalinity, and nutrient levels and colder temperatures, but
Some of the most important algae are the red, green, and brown algae, which even among themselves, differ quite a bit. Some of these algae are found in freshwater environments, but most are marine.

Jul 05, 2019 · Warm weather is a time when tiny plant-like organisms—algae and cyanobacteria—are more likely to overgrow in rivers, lakes, and oceans. These overgrowths, called algal blooms, can sometimes have foam, scum, or thick layers on the surface, or can look and smell bad. Algal blooms can also make the water appear green, red, brown, or blue.

Chrysophytes, or golden algae, are common microscopic chromists in fresh water. Some species are colorless, but the vast majority are photosynthetic. As such, they are particularly important in lakes, where they may be the primary source of food for zooplankton. Write a note on economic importance of algae and gymnosperms. Aug 30, 2019 · Economic importance of algae. Algae have diverse economic uses. They perform half of the total carbon dioxide-fixation on earth by photosynthesis, acting as the primary producers in aquatic habitats. (a) Food source: Many species of marine algae such as Porphyra, Sargassum, and Laminaria are edible. Chlorella and Spirulinaare rich in proteins. General Characteristics of Algae with Key Points ... Algae is a group of chlorophyll containing thalloid plants which bear unicellular or multicellular sex organs and the sex organs are NOT protected in the sterile jacket cells. An undifferentiated plant body is known as ‘thallus’. In thalloid plants, there is no differentiation of …
