Algae can be both micro and macro; they are classified into these two categories based on their size.
Algae encompass a diverse group of photosynthetic organisms, and their size varies considerably. They are therefore commonly categorized into microalgae and macroalgae.
- Microalgae: These are microscopic, single-celled or simple multicellular algae. They are usually not visible to the naked eye.
- Examples: Chlorella, Spirulina, diatoms.
- Macroalgae: These are large, multicellular algae, commonly known as seaweeds. They are visible to the naked eye and can grow to be several meters long.
- Examples: Kelp, Sea Lettuce (Ulva lactuca), Sargassum.
Therefore, the answer to "Is algae micro or macro?" is that algae can be either micro or macro, depending on the species. The classification is based primarily on size.
