most algae in the world is single celled but there are a few algae that are multicellular
Microscopic single-celled simple plants are classified as algae. Some algae are harmful, such as harmful algal blooms that can produce toxins, while others are beneficial, like phytoplankton that forms the base of the marine food chain.
Can be both. There are plenty of unicellular algae, such as Euglena, but most plants you see underwater are algae too (as long as they don't have flowers; a water lily is not an alga), and these are obviously multicellular. :P Oh, by the way, the singular is alga. One alga, two algae. ^^
You are referring to algae, which are single-celled organisms that can be harmful or helpful depending on the species. Some algae can produce toxins that are harmful to humans and marine life, while others provide food and oxygen and form the basis of aquatic food chains.
Many-celled organisms that make their own food are called autotrophs. They use photosynthesis to produce their own nutrients from sunlight, water, and carbon dioxide. Examples include plants, algae, and some bacteria.
No there is not
There are a lot of one celled organisms like bacteria, algae, amoeba,
Depends on the algae. Roughly speaking (this is not exhaustive), these are some of the major algal groups:Green algae - Aquatic relatives of plants.Red algae - Similar to green algae, but containing a red pigment.Brown algae - Many-celled aquatic algae, including kelp.Golden algae - Single-celled "plants" that form glass shells around them. Also called diatoms.Fire algae - Flagellate algae that whirl around when swimming. Also called dinoflagellates.
one singled celled organism is an amoeba. usally single celled organisms are surrounded by water to survive.
Yes, there are many, many one celled organisms on our planet. Some examples are algae, amoeba, and bacteria.
Algae can be single-celled or multicellular. An example of a unicellular algae is Valonia ventricosa.
