Transcript of Science: Valonia Ventricosa

Valonia Ventricosa aka. Bubble Algae and Sailor's eyes Bubble algae is one of the largest single-cell organisms. They are either spherical or ovoid and grow to usually 1-5 cm. Bubble algae are usually dark green to a grass green (depending on the number of chloroplasts), and are firm. In water, they may appear to be silver, teal, or even black. The surface of the cell shines like glass, but their cell wall is thin. Bibliography ~http://algaebase.org/search/species/detail/?species_id=13550&session=abv4:63E9DE5F1ae2000A96ppj1070410

They usually attach themselves into rock crevices and depressions, where they can easily find nutrients. Bubble algae are also a problem in salt water aquariums with rocks. The deepest that they have been found is at 80 meters Appearance Bubble algae is a plant, so it use photosynthesis for food. It takes in minerals, CO2, water and sunlight from it's surroundings for photosynthesis. Nutrients Reproduction The bubble algae uses asexual and sexual reproduction. In asexual reproduction, the mother cell's nucleus splits into 2 nuclei, and then the cell splits, creating two cells. Sexual reproduction has not been researched as much, so I couldn't find any information on it. Lifespan Because this organism reproduces by fission, it can live forever, since it keeps on splitting in 2. Emerald crabs like to eat bubble algae
