what is the difference between red tide and blue green algae?

The most notable difference is the type of water these algae prefer. Red tide does not fare well in lower-salinity waters. Most red tide blooms occur in the Gulf, but they can make their way into estuaries and bays. Blue-green algae prefers fresh waters.

Macroalgae are classified into three major groups: brown algae (Phaeophyceae), green algae (Chlorophyta), and red algae (Rhodophyta). As all of the groups contain chlorophyll granules, their characteristic colors are derived from other pigments. Many of the brown algae are referred to simply as kelp.

Algae are photosynthetic creatures. They are neither plant, animal or fungi. Many algae are single celled, however some species are multicellular. Many, but not all of red and brown algae are multicellular.

The difference between these seaweeds and submerged plants is in their structure. ... Algae are sometimes considered protists, while other times they are classified as plants or choromists. Phytoplankton are made up of single-celled algae and cyanobacteria.

Because they are photosynthetic and aquatic, cyanobacteria are often called "blue-green algae". This name is convenient for talking about organisms in the water that make their own food, but does not reflect any relationship between the cyanobacteria and other organisms called algae.

Green water is the water transpired by the plant that comes from rain water stored in soil. Blue water is the water in our surface and groundwater reservoirs.

Protists include algae, protozoa and slime molds. The major difference between algae and protozoa is that algae are able to make their own food, as plants do, while protozoa ingest other organisms or organic molecules, as animals do.

Exposure to high levels of blue-green algae and their toxins can cause diarrhea, nausea or vomiting; skin, eye or throat irritation; and allergic reactions or breathing difficulties.

Caused by the single-celled alga, Karenia brevis, red tide has been a naturally occurring phenomenon along Florida's Gulf Coast since the 1800s. Red tide is a saltwater event, not directly linked to blue-green algal blooms and Lake Okeechobee.

But a federal study going back more than a decade concluded man-made pollution worsens red tide. That makes the lake, laced with high levels of the fertilizer nutrients phosphorus and nitrogen, a likely source. What's not clear, since the same nutrients get flushed from the coast, is whether it's definitely a source.

Answer and Explanation: Algae and ferns are both green because both are plants that rely on the production of chlorophyll to create their food.

Spirulina and kelp were two key finds. Spirulina is a small, single-celled microorganism that's rich in chlorophyll, a plant pigment that gives so many lakes and ponds their dark blue-green color. Kelp, in contrast, is a brown algae that grows only in the sea.

Green algae contain the same carotenoids and chlorophyll a and b as land plants, whereas other algae have different accessory pigments and types of chlorophyll molecules in addition to chlorophyll a. Both green algae and land plants also store carbohydrates as starch. ... They are all specialized water plants.

Red algae are protists or microscopic organisms in the phylum Rhodophyta, and range from simple one-celled organisms to complex, multi-celled organisms. ... Also surprisingly, they are not technically plants, although like plants they use chlorophyll for photosynthesis and they have plant-like cell walls.

The cyanobacteria are also called the blue-green algae. ... Some of the cyanobacteria can be heterotrophs as well. The main difference between green algae and cyanobacteria is that green algae contain chloroplasts whereas cyanobacteria do not contain chloroplasts in their cells.

Column: U.S. Sugar's water is not causing red tide, algae blooms. The conversation about water has reached a fevered pitch, and rightfully so. Red Tide, blue-green algae and Lake Okeechobee discharges are all extremely serious water issues that deserve serious attention.
