Algae and Phycology
Algae is a group of aquatic plants. They are considered simple due to the fact that they do not grow into distinct parts, like land plants. Seaweed is a type of algae. Phycology is the study of algae.
560 Questions
Does different substances in water affect algae growth?
Yes, different substances in water can impact algae growth. Nutrients like phosphorus and nitrogen can promote algae growth, while pollutants like heavy metals and pesticides can inhibit growth or harm algae. Changes in pH levels and temperature can also influence algae growth rates.
How does Euglenophytes obtain energy?
Euglenophytes obtain energy through a process called photosynthesis, in which they use chloroplasts to convert sunlight into energy. They can also absorb nutrients through their cell membrane to supplement their energy needs when sunlight is not available.
What is the scientific name of a Marine Algae?
This website is the stupidest thing ever. If you are reading this, you should never go on this website ever again because half the stuff tht is on here isn't true!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Will green algae pill help with foul smelling rectal odor?
This is a rather disgusting question but I highly doubt that a "green algae" pill will help with the "foul smelling rectal odour". Try something different like air freshener or wet wipes. You can only help the smell of faeces with these things, not with drugs.
Is spirogyra blue green algae?
i dont know
i m a student of class 9 and i m searching for the answer for -
diff. b/w spirogyra and blue green alga
Yes, waterbugs may feed on algae as part of their diet. They are omnivorous and will consume a variety of food sources, including algae, plant matter, small invertebrates, and even carrion. Algae can provide an important source of nutrients for waterbugs in their aquatic habitats.
What algae has a whip like tail?
Chlamydomonas reinhardtii is a common green algae that has a whip-like tail called a flagellum. These flagella help the algae to move and navigate in aquatic environments.
What is cell structure of red algae?
Red algae, also known as Rhodophyta, have a complex cell structure. They have a distinctive red pigment called phycoerythrin that masks the green color of chlorophyll. Their cells are enclosed in a cell wall made of cellulose and have a unique pit connection system that allows for the movement of materials between cells. Additionally, red algae cells contain specialized structures called phycobilisomes that help capture light energy for photosynthesis.
How do you clear up algae in pools?
Black algae is a serious problem, particularly during the summer. In the semi-private pool we had, the technician tried to fix the problem with the water in the pool. We ended up [hired a new pool company] having to empty the pool, do the remedial things to the pool surface, replace the sand filter. It was expensive and probably would have been easier to do it the hard way first.
If it is at the bottom, brush with s/s brush turn pump off and add trichlor on top of the algae, let it seat for 2-3 days, brush again. If it is in the walls add silver based liquid algaecide as per manufacturer's recommendations.
"Black Algae" (actually blue-green algae) forms in cracks and crevices on pool surfaces, especially plaster finishes. We normally find black algae growing in, but not limited to, shady areas of the pool.
Black algae is more typically found in concrete or plaster finished pools; it is very uncommon to find it in vinyl liner pools. It is known for a heavy slime layer and "skeletal growths" that make it impervious to normal chlorine levels (1.0 - 2.5 ppm). Black algae can grow "condominium style" providing layers of algae one on top of the other. Slight cracks in plaster or fiberglass walls are perfect breeding grounds for black algae especially when the pool is not properly maintained.
Two ways to get rid of black algae, algaecides typically do not work, mainly just a waste of money. First way is to spread either cal hypo or granular triclor directly on the algae. Lower Ph so the killing form of chlorine is more effective generally 7.0 to 7.4. You first should brush the spots with a ss brush. Do not do this on a dark plaster or vinyl liner pool, chlorine will either bleach or stain color. When doing this turn off pool sweep for a few days. Second and most effective way is to get two cases of liquid chlorine 8 gallons, and two gallon of ammonia hydroxide (most pool stores can order this for you) and muriatic acid. Close the pool for two weeks. Do not let anyone swim or animals drink from the pool for at least two weeks (diarrhea). Lower pH to around 7.0 Add the 8 gallons of chlorine around the pool. Turn on filter pump let run for 24 hours at least. Now you have to add the amonia hydroxide. When you do this make sure that no one hangs around the pool for a few hours (there are some gasses from the mixture of chemicals). let your system run as normal after the 24 hours. Brush pool with ss brush as often as possible. And make sure that the pool is not use. can not stress this enough. Wait till the chlorine residual has lowered to safe levels to reuse pool. At least two weeks. May have to add more chlorine after week one depends on the amount of BA, may have to try method one during this process. What this does is with the combination of ammonia and chlorine raises the residual to around 50 ppm and burns out the BA from the root. Once this is done there will or may be etching in the plaster from were the BA was, to help with this get a sanding block from your local pool store or professional, and sand the areas were the BA was to make the plaster more uniform.
I am a pool professional and have done this on a few pools and works like magic. I have done this to a pool that was covered with black algae, tried everything on this pool and nothing else worked also did the first way that i talked about, only helped a little just slowed down.
Do not scrub the pool with acid, will do nothing other than burn plaster. You can use liquid chlorine to scrub pool, this works to kill the algae and helps to bleach the plaster and disinfects the pool when a pool was not properly sanitized. Muriatic acid is not going to kill the algae, only will temporarily make the algae disappear. If you have your pool re-plastered make sure that the plasterer cuts away the spots were the algae was. I have seen pools that had Black algae before being re-plastered and soon after new plaster was applied it came back. Some times you have to remove the gunite as well.
Caution
Mixing Any type of chlorine product with amonia hydroxide is asking for a dangerous out come. Don't Do It.
Balance your pool water, brush the algae spots with a stainless steel algae brush to break the outer shell, in a vinyl liner pool use a 3M black scrubber pad. Having done this, super shock raising Free Available Chlorine to 5 to 10 ppm add a good copper or silver based algaecide, make sure the product is chelated which will prevent staining and follow the instructions to the letter. These are products that more is not better.
Why is algae no longer classed as a plant?
Algae is no longer classified as a plant because it lacks true roots, stems, and leaves, which are defining characteristics of plants. Algae also have simpler reproductive structures and lack specialized tissues found in plants. Taxonomists have grouped algae into their own distinct kingdom, separate from plants, due to these differences.
What is the major limiting factor in Mono Lake algae that effects everything else?
The major limiting factor in Mono Lake algae is phosphorus availability. Phosphorus is essential for algae growth, and the low levels of phosphorus in Mono Lake limit the algal population, which in turn affects the entire ecosystem as algae form the base of the food web.
What chemical do algae release?
Algae can release a variety of chemicals, including oxygen, organic compounds like amino acids and fatty acids, as well as toxins such as microcystins and domoic acid. The specific chemicals released by algae depend on the species and environmental conditions.
Why are algae important for fish that do not eat algae?
Algae, like all other plants, provides oxygen. All living things, including fish, need oxygen to survive. In the process of photosynthesis, the plant takes in carbon dioxide and gives off oxygen. Algae and all other plants are vital to the well being of the water ecosystem.
Is algae an example of saprophyte?
No, algae are not saprophytes. Algae are photosynthetic organisms that produce their own food using sunlight and carbon dioxide. Saprophytes are organisms that obtain nutrients by decomposing dead organic matter.
What are four body forms of algae?
- Unicellular: Algae like Chlorella are single-celled organisms.
- Colonial: Algae such as Volvox form colonies of cells.
- Filamentous: Algae like Spirogyra form long chains of cells.
- Thalloid: Algae such as kelp have a plant-like body structure with differentiated tissues.
What are home remedies to kill algae in ingroud pools?
Chlorine bleach kills algae. That's why chlorine is used in swimming pools. Be careful when using chorine bleach. It should not be mixed with other cleaners. Use it in a well ventilated area. It is very powerful and should be diluted.
Algae are unicellular plants- and so they make their own food by photosynthesis. i won't highlight all the biochemistry in detail, but the following equation sums up the reaction:
6H2O + 6CO2 (+ Sunlight) = 6O2 + C6H12O6
The equation above states that water and carbon dioxide are converted into glucose( the plant's food) and oxygen as a waste product- using light energy to drive the reaction.
What are the most important differences among the three phyla of multicellular algae?
The three main phyla of multicellular algae are Chlorophyta (green algae), Phaeophyta (brown algae), and Rhodophyta (red algae). They differ in terms of photosynthetic pigments, cell wall composition, and storage polysaccharides. Chlorophyta have chlorophyll a and b, with cellulose cell walls and starch reserves. Phaeophyta have chlorophyll a and c, with algin and cellulose cell walls and laminarin reserves. Rhodophyta have chlorophyll a and phycobiliproteins, with cellulose cell walls and floridean starch reserves.
What part of the large algae that takes the place of roots and anchors to the ocean floors?
Holdfasts are the structures in large algae that take the place of roots. These holdfasts anchor the algae to the ocean floor, providing stability and allowing the algae to withstand ocean currents and waves.
How long does brown algae take reproduce?
Brown algae reproduce through spores or fragmentation, with the time it takes to reproduce varying among different species. In general, brown algae can reproduce relatively quickly compared to other organisms, with some species capable of producing spores within a few weeks under favorable conditions.
Why are algae called thallophytes?
Algae are called thallophytes because they are simple, plant-like organisms that lack true roots, stems, or leaves. Thallophytes have a body plan known as a thallus, which is a undifferentiated structure that lacks specialized tissues. Algae exhibit this structure, hence the classification as thallophytes.
What food contain green algae?
Only some healthfood supplements. Green algae (or any type of algae, for that matter) is not commonly added to foodstuffs and does not occur naturally in many foodstuffs either. Sushi or sashimi does not contain algae - it contains nori seaweed.
Which is a possible reason for the transition of algae from unicellularity to multicellularity?
One possible reason for algae transitioning from unicellularity to multicellularity is to increase their overall size and surface area, which can enhance their ability to absorb nutrients and photosynthesize more efficiently. Multicellularity may also provide algae with better protection against predators and adverse environmental conditions, as well as improve their reproductive strategies through enhanced dispersal and reproduction.
Do blue green algae need the sun?
No. Only animals need sun. Animals have a process called hydrosynthesis, which is using the sun's luminosity to digest water.
