How can can plasmolysis be demonstrated in the laboratory using a filament of spirogyra?
To demonstrate plasmolysis with a filament of spirogyra in the laboratory, place the filament in a hypertonic solution such as salt water. As water leaves the cell by osmosis, the cytoplasm shrinks away from the cell wall, leading to the detachment of the cytoplasm from the cell wall, demonstrating plasmolysis. This can be observed under a microscope.

Why do all cell in a spirogyra filament look different?
no no
How does the growth of filament occurs in spirogyra?
Filamentous growth in Spirogyra occurs through the repeated divisions of its cylindrical cells, resulting in the elongation of the filament. Each cell contains a single spiral chloroplast that enables photosynthesis. As the cells divide, the filament grows in length, maintaining its characteristic spiral structure.
What happens during conjugation in Spirogyra?
a form of sexual reproduction. Spirogyra and its relatives can be found during summer as pond scum, floating mats in ponds.Two filaments of Spirogyra form conjugation tubes. The contents of one cell passes through the tube an fuses with a cell from the other filament.
How does the spirogyra grow and develop?
Spirogyra grows and develops through a process called fragmentation, where a single filament breaks apart to form new filaments. These new filaments then grow through cell division, expanding the colony size. As the filaments continue to grow, they form dense mats or clumps in freshwater environments.
What is the function of akinates in spyrogyra?
Akinetes in Spirogyra serve as dormant cells that are formed during unfavorable conditions like extreme temperatures or nutrient scarcity. These akinetes can remain dormant until conditions improve, allowing Spirogyra to survive and reproduce when conditions are more favorable.

What happens when plasmolysed spirogyra filament is put in water?
When a plasmolysed Spirogyra filament is put in water, the cell membrane will rehydrate and regain its original shape. The water will move into the cell through osmosis, causing the cell to become turgid again. This process is known as deplasmolysis, where the protoplast swells and pushes the cell membrane against the cell wall.
Is spirogyra a single-celled organism?
No, spirogyra is not a single-celled organism. It is a type of multicellular green algae that forms long, filamentous structures composed of chains of cells. Each cell within the filament contains a single nucleus.

Is spirogyra helpful to humans?
Spirogyra is a green algae having a filamentous structure, which measures about 10-100 micrometer in width. The length of the filament is long and may stretch up to several centimeters. Believe it or not, more than 400 species of spirogyra algae are identified from freshwater habitats. One of the distinctive spirogyra facts is the presence of spiral or helical shaped chloroplast visible under microscope, hence the name. This characteristic feature is used as an identifying attribute for spirogyra genus.it invented the dildo
Is Spirogyra a unicellular organism or multicellular?
Spirogyra is a colonial plant. It consists of many identical cells, reapeated one after the other in a strand, and it is classified as a green algae. It is autotrophic, meaning it gets energy from the sun and not from other creatures. Its name, spirogyra, comes from his genus's trademark spiral shaped chloroplasts.

Who was the African American to patent an invention in 1881?
Lewis Howard Latimer worked in Thomas Edison's engineering laboratory, and patented an electric lamp in 1881 and a carbon filament for bulbs in 1882.
