What is the difference between Rhodophyta and Phaeophyta?
What is the difference between Rhodophyta and Phaeophyta?
Red algae are classified under Rhodophyta, and brown algae are classified under Phaeophyta while green algae are classified under Chlorophyta. Hence, this is one important difference between red brown and green algae.
How does Phaeophyta reproduce?
The flagella retract and the Sperm fuses with the Egg (Syngamy/Fertilization). The Zygote divides to produce the Sporophyte Generation. The sporophyte produces Plurilocular MITOsporangia which produce Diploid Spores. This is a form of ASEXUAL reproduction.
Why is Phaeophyta important?
They are an important component of the aquatic food chain as primary producers. Kelp forests support large numbers of animals. They are widely used as edible seaweeds, e.g. Laminaria, Sargassum, etc.
What is the advantages of brown algae?
Brown algae contain several chemicals that work as antioxidants. These chemicals are thought to prevent damage to the body that can lead to cancer and other conditions. Chemicals contained in brown algae might also have effects on inflammation and the body’s immune system.
Are Phaeophyta unicellular or multicellular?
multicellular
Phaeophyta are group of multicellular, eukaryotic organisms that belong to the class phaeophyceae in the division chromophyta.
How does Phaeophyta store food?
Phaeophyta stores food in the form of complex polysaccharides, alcohol and sugar. The chief source of carbohydrate is a substance known as laminarine.
What are the salient features of Phaeophyta?
Phaeophyta or brown algae are a group of autotrophic, multicellular organisms, belonging to the class Phaeophyceae in the division Chromophyta. They contain the xanthophyll pigment – fucoxanthin, in addition to chlorophyll a and c. Hence, the members of phaeophyta exhibit a characteristic greenish-brown color.
What is Phaeophyta in biology?
Phaeophyta (brown algae) A division of algae which includes no single-celled species; almost all are marine, growing mostly in the intertidal regions (but species of Bodenella and Heribaudiella occur in fresh water). They are the dominant seaweeds in the colder waters of the northern hemisphere.
What is the characteristics of Phaeophyta?
The Phaeophyta (brown algae) are characterized by five chief distinguishing features: (1) the photosynthetic pigments include chlorophyll-a and chlorophyll-c, β carotene, fucoxanthin, violaxanthin, diatoxanthin and other xanthophylls, and in general there is an excess of carotenoid over chlorophyll pigments; …
What are the characteristics of phylum Phaeophyta?
What is the storage product of the Phaeophyta?
Phaeophyta stores food in the form of complex polysaccharides, alcohol and sugar.
