Spirogyra is a filamentous type of algae found in freshwater habitats. Two of the most interesting spirogyra facts are presence of spiral shape chloroplasts and reproduction by conjugation method. Spirogyra is a green algae having a filamentous structure, which measures about 10-100 micrometer in width. ...

How long is a spirogyra?
Spirogyra grows in the form of green filaments that together form green clumps throughout the plates or bioreactors. Depending on the species, the length of the filaments can range from 100-600 µm with the width ranging from 10-100 µm.
Is spirogyra a plant or animal?
A spirogyra is plant-like because of the presence of chlorophyll which allows it to make its own food.
Why spirogyra is so called?
Named for their beautiful spiral chloroplasts, spirogyras are filamentous algae that consist of thin unbranched chains of cylindrical cells. They can form masses that float near the surface of streams and ponds, buoyed by oxygen bubbles released during photosynthesis.
What does spirogyra feed on?
Spirogyra Longata performs photosynthesis to receive its nutrients. This alga contains special cells called stomata that open and close so the organism can take in carbon dioxide and release oxygen during the chemical reaction in photosynthesis.
Is algae a plant or animal?
Algae are sometimes considered plants and sometimes considered "protists" (a grab-bag category of generally distantly related organisms that are grouped on the basis of not being animals, plants, fungi, bacteria, or archaeans).
Can spirogyra move?
Spirogyra form long filaments, and it's the bending and curving of these filaments that allow these protists to move, albeit slowly, to orient themselves towards light.
Can amoeba make its own food?
Some people say it looks like "pea soup." You will find them in water such as ponds or marshes. They can make their own food like a plant, but they can also eat other things, like an animal. They can also swim and move.
Who eats Spirogyra?
Spirogyra is an organism at the base of aquatic food chains. They are eaten by seed shrimp, aquatic worms of all types, freshwater snails, and fish.
Is Sea Lettuce an animal?
L. Ulva lactuca, also known by the common name sea lettuce, is an edible green alga in the family Ulvaceae. It is the type species of the genus Ulva.
What is dwarf male filament?
Dwarf males are small, short, antheridium-producing filaments attached near the oogonia (female sex organ). These dwarf males are derived by repeated cell division of multiflagellate androspores.
What is spirogyra short answer?
Spirogyra (common names include water silk, mermaid's tresses, and blanket weed) is a filamentous charophyte green alga of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is characteristic of the genus.
Where does spirogyra grow?
Spirogyra is a large genus (about 400 species) of freshwater green algae found in shallow ponds, ditches and amongst vegetation at the edges of large lakes, generally growing free-floating. It often grows in short-lived ('ephemeral') ponds that build up during wet weather, and dry up subsquently.
What is a cell?
In biology, the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm. ... Parts of a cell. A cell is surrounded by a membrane, which has receptors on the surface.
How do Chlamydomonas eat?
Chlamydomonas makes its food in the same way as green plants, but without the elaborate system of roots, stem and leaves of the higher plants. It is surrounded by water containing dissolved carbon dioxide and salts so that in the light, with the aid of its chloroplast, it can build up starch by photosynthesis.
Why is spirogyra harmful?
These aquatic filamentous algae of the genus Spirogyra have a cosmopolitan distribution and includes over 600 freshwater species. ... The dead fronds of filamentous algae can also contaminate waters, including drinking water sources, with the products of their decomposition.
