These blooms can produce toxins that make people and animals sick. Sometimes these bacteria can cause more serious lung infections that require care in a hospital. Spirogyra (common names include water silk, mermaid's tresses, and blanket weed) is a genus of filamentous charophyte green algae of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is characteristic of the genus. The process in which certain unicellular organisms engulf other cells, which become endosymbionts and ultimately organelles in the host cell. True Avoid eating shellfish that live in coastal areas that have a high influx of nutrients Class: Chlorophyceae *4.) The index will continue to evolve as additional topics are added.

C. the egyptian pyramids are built of this type of limestone The size of the zygospore and the nature of the spore membrane are also studied to obtain proper identification. Some species like. The zygospore then divides meiotically to form four haploid nuclei, out of which only one survives. The breakdown of the filament to form individual fragments might occur either due to mechanical injury, dissolution of the middle lamella, or the formation of H-shaped fragments. 2.

Depending upon the thickness of the cell wall and their ability to move, spores inSpirogyracan be of three types aplanospores (thin-walled and non-motile), akinetes (thick-walled and non-motile) and azygospores (thin-walled and motile). Learn how to check for health advisories, report blooms, and prevent blooms from forming. You can review and change the way we collect information below. Figure: Morphology of Spirogyra. Kinetoplastids feed on many prokaryotes and are also parasites, they can cause Chagas disease, which is transmitted by blood-sucking insects and can lead to congestive heart failure. Lyme disease is caused by the bacterium Borrelia burgdorferi and is transmitted to humans through the bite of infected blacklegged ticks (also known as deer ticks)..

What happens? sexual reproduction occurs when condition deteriorate, and the formation of the spores allow protists to live in hostile environments. The various forms of algae are NOT considered plants because they Asexual reproduction is thus a form of adaptation inSpirogyra. Cells are similar to those of Spirogyra in containing 2-10 parietal, ribbon-like chloroplasts. These descended from the ancient protist that engulfed a cyanobacterium. The term "protists" is used to refer to eukaryotes that are not plants, animals or fungi.
