Differences between Algae and Seaweed

An Introduction of Algae and Seaweed

Algae are chlorophyll-containing organisms that are found in ponds, sea, freshwater, marine water bodies, and snow as well. Depending upon their classes and where they grow, the color and the properties of algae varies. For example, the algae that grow in fresh water are often green in color, but the one that inhabit the sea can be of the green color, red color, or brown color.

And, the best thing to know is Seaweed is a type of algae that grow in the sea under shallow or deep water depending upon its type. Seaweed grows very fast and up to 230 feet, creating a forest under the water. You see them on the shores or waving in the seas during tidal waves.

Seaweeds are considered as plants, but they are not actually plants but perform photosynthesis similar to the plants on the earth. They need the sunshine to process the nutritional elements collected / absorbed from the water and surroundings. They are categorized into three types of algae namely red, brown, and green that collectively has above 10000 species. Green seaweeds are mostly produced in the freshwater while red and brown species are mostly found in marine water bodies.

Differences between Algae and Seaweed

  • Seaweeds are a type of algae that has unique properties such as macroscopic, multicellular, benthic, and marine
  • The history of Algae is much older than of seaweeds
  • Algae has a wide range of species, but seaweeds have about 10000 species only
  • Seaweeds are multi-cellular but algae can be multicellular and unicellular as well
  • Seaweeds have autotrophic characteristics, but some species of algae depends on other food sources
  • Seaweeds can only be found in the sea but algae grow in fresh and marine water bodies, including sea, lake, pond, etc.
  • Algae can grow in shallow and deep water, but seaweeds often grow in shallow water
