Does spirogyra have specialized cells?

Does spirogyra have specialized cells?

The chloroplasts form a spiral around the vacuole and have specialized bodies known as pyrenoids that store starch. The cell wall consists of an inner layer of cellulose and an outer layer of pectin, which is responsible for the slippery texture of the algae.

What is filament in spirogyra?

Spirogyra has long, unbranched filaments with cylindrical cells that are connected end to end. The cell wall is made up of an outer layer of pectin and an inner layer of cellulose. The inner surface of the cell wall is lined with a thin layer of cytoplasm.

What is the main function of algae?

They play a vital role in aquatic ecosystems by forming the energy base of the food web for all aquatic organisms. As autotrophic organisms, algae convert water and carbon dioxide to sugar through the process of photosynthesis.

What are the diseases caused by algae in animals?

ciguatera fish poisoning – CFP. diarrhetic shellfish poisoning – DSP. neurotoxic shellfish poisoning – NSP. paralytic shellfish poisoning – PSP.

Why is lots of algae bad?

Harmful effects. As algal blooms grow, they deplete the oxygen in the water and block sunlight from reaching fish and plants. And when the algae eventually die off, the microbes which decompose the dead algae use up even more oxygen, which in turn causes more fish to die or leave the area.

Can you swim in a pool with a little bit of algae?

Algae is not harmful to swimmers per se, but pools with algae may also be a safe harbor for pathogens like E-coli bacteria. Algae create a chlorine demand in the water for itself, consuming chlorine that should be working on other contaminants. As it expels carbon dioxide, the pH level of pool water can rise.

How much shock does it take to kill algae?

(1 bag) of shock per 10,000 gallons of pool water. That may be fine for normal conditions, but if you have a severe algae attack, a triple shock is needed. 1 bag will get reach 7-9 ppm, but for 30 ppm, you need 3, 4 or sometimes even 5+ lbs per 10,000 gallons of pool water.
