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
Is a gelling agent derived from algae that is useful for creating solid growth media?
Yes, a gelling agent derived from algae, such as agar, is commonly used in creating solid growth media for various microbiological applications. Agar provides a solid surface for microbial growth, allows for uniform dispersal of nutrients, and is easily sterilized. It is a versatile and reliable component in laboratory settings.
Were does green algae live in the ocean?
Green algae can be found living in various habitats within the ocean, such as in intertidal zones, coral reefs, and even in deep-sea environments. They can attach themselves to rocks, inhabit sandy ocean floors, or even float freely in the water column. Green algae are versatile organisms that can thrive in a range of conditions throughout the ocean.
How might a sea star avoid being covered by sand or algae?
A sea star can avoid being covered by sand or algae by actively moving or using tube feet to crawl away to a new location. They can also use their adhesive tube feet to grip onto rocks or other hard surfaces to prevent being buried. Additionally, some species have protective spines or bumps on their surface that deter sand or algae from covering them.
Why would an algae have a subcuticular thallus?
An algae with a subcuticular thallus may have developed this structure to provide protection from desiccation or to enhance gas exchange. The subcuticular thallus allows the algae to remain hydrated and obtain necessary resources from its environment while minimizing water loss and potential damage.
Where are green algae or other photosynthetic organisms likely to thrive in the ocean?
Green algae and other photosynthetic organisms are likely to thrive in the ocean in areas with ample sunlight penetration, shallow waters, and nutrient-rich environments. Coastal regions, coral reefs, and areas with upwelling currents tend to support high concentrations of these organisms due to the availability of sunlight and nutrients for photosynthesis.
Why is everything directly or indirectly dependent on algae?
Algae play a crucial role in the ecosystem by producing oxygen through photosynthesis, serving as a food source for various aquatic organisms, and influencing nutrient cycling in aquatic environments. They also contribute to regulating the Earth's climate by sequestering carbon dioxide from the atmosphere. This makes them essential for the functioning and balance of aquatic ecosystems and ultimately impacts various aspects of life on Earth.
Are diatoms a glimpse at gods perfect creation in their symmetry?
Diatoms are a type of algae with intricate and beautiful patterns due to their unique cell walls made of silica. While their symmetrical shapes are indeed mesmerizing, they have evolved over millions of years through natural selection and adaptation to their environment rather than being a reflection of a divine creator.
What are the 3 things in fertilizer that cause algae to grow?
The three main components found in fertilizer that can cause algae to grow are nitrogen, phosphorus, and potassium. When these nutrients are washed into water bodies, they can stimulate algae growth, leading to excessive algae blooms that can harm aquatic ecosystems.
What are facts about brown algae?
Brown algae are multicellular seaweeds that are primarily marine in habitat. They are rich in alginates, which are used commercially in food and other products. Brown algae can vary widely in size, from small species to giant kelps that can reach lengths of over 100 feet.
Important role do diatoms play in modern Earth systems?
Diatoms are crucial in modern Earth systems because they are responsible for a significant portion of global carbon fixation through photosynthesis. They are also an important source of food for various marine organisms and contribute to the ocean's biological productivity. Additionally, diatoms play a role in regulating the Earth's climate by influencing the carbon cycle and helping to remove carbon dioxide from the atmosphere.
What is unicellular algae surrounded by thick plates of armor called?
Unicellular algae with thick plates of armor are called diatoms. These phytoplankton have a unique cell wall made of silica, forming intricate patterns and shapes.
What is smaller algae or fungi?
Algae are typically smaller than fungi. Algae are simple, plant-like organisms that can range from microscopic sizes to large seaweeds, while fungi are a group of organisms that include microscopic forms like yeasts as well as larger forms like mushrooms.
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.
