Interesting Facts About Algae
- Algae is a one-celled plant that can grow in your pool if conditions are favorable.
- There are over 400,000 known varieties of algae.
- Algae are mainly found in marine or freshwater environments.
- Algae produce oxygen which other aquatic life uses.
What are 2 facts about algae?
Genome sequencing has found algae in four different kingdoms: Plantae, Chromista, Protista, and Bacteria. Algae can be unicellular or as large as a tree like the giant sea kelp. Algae are typically photosynthetic, meaning they need carbon dioxide and sunlight to grow – just like plants.Jun 12, 2017
What are some fun facts about algae?
There are more algae in the oceans than stars in the Universe. Algae are the base of the marine food chain: without algae, there would be no fish or any other sea animals. All plants evolved from algae. Without plants to eat, fish would never have evolved to become land animals, including us.Aug 2, 2019
What are 2 reasons that algae are very important?
They play a vital role in aquatic ecosystems by forming the energy base of the food web for all aquatic organisms. As autotrophic organisms, algae convert water and carbon dioxide to sugar through the process of photosynthesis.
What is a fun fact about green algae?
✦ There are about 7000 species of green algae, which can be found in both fresh or saltwater and also in damp places. ✦ They are considered as the group from which the higher plants evolved on the basis of certain characteristics, and the compounds found in the pigments used for photosynthesis.
What are 5 things algae needs to survive?
What are Algae? > Algae reproduce very quickly and need only sunlight (or another form of energy, like sugar), water, carbon dioxide and a few inorganic nutrients to grow.
What do algae need to survive?

What helps algae survive in the ocean?
Algae require warmth, sunlight, and nutrients to grow and reproduce, so they live in the upper 60 to 90 meters (200 to 300 feet) of ocean water. The upper layer of water, the epipelagic zone, is rich in oxygen, penetrated by sunlight, and warmer than water at lower levels.
Does algae need air to survive?
When green algae "can't breathe," they get rid of excess energy through the production of hydrogen. Biologists have found out how the cells notice the absence of oxygen. For this, they need the messenger molecule nitric oxide and the protein haemoglobin, which is commonly known from red blood cells of humans.Jun 21, 2013
