CHARACTERISTICS OF ALGAE ARE
Algae are eukaryotic organisms that have no roots, stems, or leaves but do have chlorophyll and other pigments for carrying out photosynthesis. Algae can be multicellular or unicellular. Unicellular algae occur most frequently in water, especially in plankton.
CHARACTERISTICS OF SPIROGYRA ARE
It is a multi-cellular filamentous algae with mucilagenouus sheath.It consists of spiral chloroplast.Cell wall layer is made up of cellulose and pectin.The chloroplast of spirogyra consists of pyrenoids.Cytoplasm lie on the periphery of cell.
> Giant kelp, brown algae are some examples of multicellular algae.
Hope it helps you dear...
Algae (/ˈældʒi, ˈælɡi/; singular alga /ˈælɡə/) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping, including species from multiple distinct clades. Included organisms range from unicellular microalgae, such as Chlorella and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to 50 m in length. Most are aquatic and autotrophic and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem, which are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the Charophyta, a division of green algae which includes, for example, Spirogyra and stoneworts.
