Algae are photosynthetic eukaryotes that belong to the polyphyletic clades of photosynthetic eukaryotes. Algae have the same cell division and fragmentation as humans.
Algae reproduce via regeneration, which is a form of sexual reproduction.
Algae may grow swiftly if given the right nutrition and habitat, but this varies from species to species.
Microalgae can double in size in less than 24 hours, compared to conventional algae.
Seaweed is a type of algae-like macroalgae that grows to a typical size in the ocean. Plant fertilizer can offer extra nutrients in algae growth by being applied to a specific culture where algae are growing.
