Algae are sometimes considered plants and sometimes considered “protists” (a grab-bag category of generally distantly related organisms that are grouped on the basis of not being animals, plants, fungi, bacteria, or archaeans).
Is algae a fungus or bacteria?
Protists. Protists are unicellular eukaryotes that are not plants, animals, or fungi . Algae and protozoa are examples of protists. Algae (singular: alga) are plant-like protists that can be either unicellular or multicellular (Figure 4).
Are algae bacteria?
Algae are sometimes considered plants and sometimes considered “protists” (a grab-bag category of generally distantly related organisms that are grouped on the basis of not being animals, plants, fungi, bacteria, or archaeans).
What is algae classified?
algae, singular alga, members of a group of predominantly aquatic photosynthetic organisms of the kingdom Protista . Algae have many types of life cycles, and they range in size from microscopic Micromonas species to giant kelps that reach 60 metres (200 feet) in length.
Is algae caused by bacteria?
The development and proliferation of algal blooms likely result from a combination of environmental factors including available nutrients, temperature, sunlight , ecosystem disturbance (stable/mixing conditions, turbidity), hydrology (river flow and water storage levels) and the water chemistry (pH, conductivity, ...
Why is algae so bad?
Harmful algae and cyanobacteria (sometimes called blue-green algae) can produce toxins (poisons) that can make people and animals sick and affect the environment. ... Algae and cyanobacteria can rapidly grow out of control, or “bloom,” when water is warm, slow-moving, and full of nutrients.
Where is algae found?
Algae are aquatic, plant-like organisms. They encompass a variety of simple structures, from single-celled phytoplankton floating in the water, to large seaweeds (macroalgae) attached to the ocean floor 2 . Algae can be found residing in oceans, lakes, rivers, ponds and even in snow, anywhere on Earth .
Is algae considered mold?
Algae and mold are different but equally harmful to your property. Mold is a fungus that will eat nutrients to survive. Algae is more plant-like and eats the limestone filler in shingles and organic matter on a home's siding.
Who eats algae?
Phytoplankton and algae form the bases of aquatic food webs. They are eaten by primary consumers like zooplankton, small fish, and crustaceans . Primary consumers are in turn eaten by fish, small sharks, corals, and baleen whales.
What is the basic difference between bacteria and algae?
| Bacteria Algae | Domain Prokaryote Eukaryote | Cell walls Cell walls are make of peptidoglycan. Cell walls are composed of components such as cellulose, proteins, agar, carrageenan, silicates, algin, calcium carbonate. | Nucleus Absent Present | Size A few micrometers in length From microscopic to meters long |

What is algae give two examples?
Multicellular examples of algae include the giant kelp and brown algae . Unicellular examples include diatoms, Euglenophyta and Dinoflagellates. Most algae require a moist or watery environment; hence, they are ubiquitous near or inside water bodies.
What are the 3 main types of algae?
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.
What is algae Short answer?
Algae are a diverse group of aquatic organisms that have the ability to conduct photosynthesis. Certain algae are familiar to most people; for instance, seaweeds (such as kelp or phytoplankton), pond scum or the algal blooms in lakes.
What are the harmful effects of algae?
Drinking algae-affected water or consuming food (such as fish or shellfish) containing toxins can lead to gastroenteritis, which can induce vomiting, diarrhoea, fevers and headaches . These toxins may also affect the liver or nervous system.
How can you tell if algae is toxic?
What do toxic algae look like? Toxic algae can look like foam, scum, or mats on the surface of water , said Schmale. Harmful algae blooms, which can be blue, vibrant green, brown or red, are sometimes mistaken for paint floating on the water.
How do you know if algae is toxic?
There is no way to tell if a blue-green algal bloom is toxic just by looking at it. Adults, children, and animals should avoid contact with water with blue-green algae. Toxins can persist in the water after a bloom; watch for signs of recent blooms, such as green scum on the shoreline. When in doubt, stay out!
