Algae/Representative species
What is algae kid friendly definition?
Algae are organisms, or living things, that are found all over the world. Algae are very important because they make much of Earth’s oxygen, which humans and other animals need to breathe. Some algae, such as seaweed, look like plants.
What are algae one word?
Algae (/ˈældʒiː, ˈælɡiː/; singular alga /ˈælɡə/) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms.
Where algae are found?
Algae are a group of plants that are usually found in water. Like all plants, algae have a pigment called chlorophyll that they use to turn sunlight into food. Algae can be found in all types of waters, including salt water, fresh water, and brackish water (a mix of salt and fresh water).

Is algae harmful to humans?
Harmful algae and cyanobacteria, sometimes called blue-green algae, can produce toxins (poisons) that can make people and animals sick and affect the environment. Learn more about them to keep you, your family, and your pets safe. Algae and cyanobacteria are simple, plant-like organisms that live in water.
Can you eat algae?
You may be familiar with eating seaweed already, thanks to delicious menu items like nori-wrapped sushi—but the world of edible algae extends well beyond your favorite spicy tuna roll to include varieties like chlorella, spirulina, and sea moss.
Is algae a plant or fungi?
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 kind of plant is algae?
In general algae can be referred to as plant-like organisms that are usually photosynthetic and aguatic, but do not have true roots, stems, leaves, vascular tissue and have simple reproductive structures. They are distributed worldwide in the sea, in freshwater and in moist situations on land.
What are the 4 main types of algae?
Algae belong to the kingdom Protista, and are simple photosynthetic organisms. Based on the occurrence of pigments and food reserves, algae are classified into different types, namely blue green algae (BGA), green algae, red algae, and brown algae.
Why does algae grow in water?
Thick layers of algae, called algal blooms, may form when nutrients (mainly phosphorus and nitrogen) build up in the water in amounts in excess of naturally-occurring nutrients. Fertilizers, pet waste, improperly functioning septic tanks, grass clippings, leaves, and other yard wastes are all sources of nutrients.
How fast do algae grow?
Algae growth should reach its peak by 30 days/4 weeks, though you don’t need to wait that long to harvest the algae.
Is algae in drinking water harmful?
In addition to the health symptoms mentioned earlier, drinking water with high levels of blue-green algal toxins has been associated with effects on the liver and on the nervous system in laboratory animals, pets, livestock, and people.
What does algae need to survive?
Algae only require a few essentials to grow: water, sunlight, carbon, and nutrients like nitrogen and phosphorus. From salt water to fresh water and everything in between, the diversity of algae means that there are suitable strains that can take advantage of nearly any water resource.
Can algae grow without water?
Algae is a lot like art in that sense too. To grow and prosper algae need water – they’re aquatic organisms. No water, no algae. They need sunlight – algal cells contain chlorophyll which enables ’em to photosynthesize, i.e., using sunlight to convert carbon dioxide into cellular material.
Can algae grow in pure water?
Algae can be cultured in distilled water, tap water or Milli-Q water depending on the requirements. For domestic requirements, such as bio-fertilizers and bio-remediating agents, tap water is one of the best water sources, as it already contains essential extra nutrients required for algae to grow.
What does an algae eat?
Algae does not consume organic materials; instead, it feeds on the waste materials produced by decomposing materials and the waste of marine animals. The growth of algae is dependent on the process of photosynthesis where the bacteria that forms the organisms takes energy from the rays of the sun to use for growth.
What is algae good for?
People use blue-green algae for treating high blood pressure and as a protein supplement. It’s also used for high levels of cholesterol or other fats (lipids) in the blood, diabetes, obesity, and many other conditions.
What kills algae in the ocean?
Scientists have confirmed that viruses can kill marine algae called diatoms and that diatom die-offs near the ocean surface may provide nutrients and organic matter for recycling by other algae, according to a Rutgers-led study.
What is algae made of?
Algae is composed of ~ 50% carbon, 10% nitrogen, and 2% phosphorus. Table 10.3 shows the composition of various algae looking at the percentages of protein, carbohydrates, lipids, and nucleic acid.
How do algae grow?
How does algae grow? Algae grow by photosynthesis. For this they need sunlight and nutrients, such as phosphorus and nitrogen. An overabundance of nutrients usually leads to excessive algal growth, which can have adverse effects on the ecosystem.
Do algae have DNA?
The nucleus contains most of the genetic material, or deoxyribonucleic acid (DNA), of the cell. In most algae, the molecules of DNA exist as linear strands that are condensed into obvious chromosomes only at the time of nuclear division (mitosis).
