Spirogyra
Spirogyra (Product Code: SCL455/0178) is a prepared microscope slide of the filamentous green alga Spirogyra, used to show spiral chloroplasts and algal cell structure in school and college botany practicals. Teachers pick it for lessons on algae, plant cells and photosynthesis because the ribbon-like chloroplasts are easy to recognise; the specimen is mounted on clear borosilicate glass and kept in a white plastic box. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as one of its prepared microscope slides.

What Is the Spirogyra Slide Used For?
The slide is used to teach how a simple green alga is built. Each filament is a chain of cylindrical cells joined end to end; under high power students follow the spiral chloroplast as it winds round the inside of the cell wall, spot the pyrenoids spaced along it, and find the nucleus held in the middle of the cell by fine strands of cytoplasm crossing a large vacuole. Counting the chloroplast ribbons in a cell and comparing how tightly they coil in different filaments make good tasks for a practical record.
Spirogyra is also the textbook example of sexual reproduction by conjugation, in which a tube forms between cells of neighbouring filaments; the stage on this slide is not specified in our listing, so check with us if you need it. The slide fits botany lab equipment collections for school and undergraduate courses, and pairs naturally with fresh pond material mounted on plain slides and tested with iodine, which shows starch around the pyrenoids.
Supplier

Frequently Asked Questions
Why does Spirogyra look spiral under the microscope?
Spirogyra looks spiral because each cell contains ribbon-shaped chloroplasts that coil around the inside of the cell wall. On the Spirogyra slide students can trace these ribbons at high power and pick out the pyrenoids spaced along them, which is the feature that gives the alga its name.
Does the Spirogyra slide show conjugation?
The reproductive stage on the Spirogyra slide (SCL455/0178) is not stated in our product details, so please contact us before ordering if your syllabus needs conjugation. A separate slide listed as Conjugation of Spirogyra, Whole Body can be quoted for that stage.
Is the Spirogyra slide useful for photosynthesis lessons?
Yes, as a visual aid. The Spirogyra slide lets students see the chloroplasts and the pyrenoids linked to starch storage, which helps explain where photosynthesis happens. For actual photosynthesis experiments, such as starch tests, fresh pond material mounted on plain slides works better.
What comes in the Spirogyra slide box?
The Spirogyra slide is mounted on clear borosilicate glass and packed in a white rectangular plastic box. Our listing does not state how many slides each box holds, so the quantity per box is confirmed with your quotation.
How should the Spirogyra slide be stored in a humid climate?
Keep the Spirogyra slide in its closed box in a dry cupboard, away from sinks and steam. Damp conditions can leave a film on glass surfaces, so if the slide looks cloudy, wipe it gently with lens tissue before use.
Who supplies the Spirogyra slide?
The Spirogyra slide is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab) of Ambala, Haryana, India. The company sources prepared slides for schools, colleges, institutions and dealers, and quotes for delivery within India and to international markets.
What should a quotation request for the Spirogyra slide include?
Send the product code SCL455/0178, the number of Spirogyra slides you need, your delivery location and any other botany slides or reagents on your list. ScienceLab then prepares a single quotation covering the whole requirement.
