characteristics of three phyla of algae
Green algae
characteristics
Algae are photosynthetic organisms.
Algae can be either unicellular or multicellular organisms.
Algae lack a well-defined body, so, structures like roots, stems or leaves are absent.
Algaes are found where there is adequate moisture.
Reproduction in algae occurs in both asexual and sexual forms.
Red algae
characteristics
Most red algae in phylum Rhodophyta (roh dah FI duh) are multicellular.
These organisms contain red photosynthetic pigments called phycobilins (fīkōˈbīlin ) that give them a red color.
These pigments enable the red algae to absorb green, violet, and blue light that can penetrate water to a depth of 100 m or more.
This allows red algae to live and photosynthesize in deeper water than other algae.
Brown algae
characteristics
Brown algae are members of phylum Phaeophyta (FAY oh FI tuh)
.
They get their brown color from a secondary carotenoid pigment called fucoxanthin (fyew ko ZAN thun)
Most of the 1500 species of brown algae live along rocky coasts in cool areas of the world.
Kelp is an example of a brown algae.
Some of the largest multicellular plantlike algae.
