Red Algae Also known as rhodophyta, these were among the first eukaryotic organisms on the planet, and their signatures have been found in rocks almost 2 billion years old. They are mostly marine organisms, and include many types of seaweed, as well as a number of single-celled species. The...
Comparisons of pollen coat genes across Brassicaceae species reveal rapid evolution by repeat expansion and diversification Reproductive genes and traits evolve rapidly in many organisms, including mollusks, algae, and primates. Previously we demonstrated that a family of glycin... F Aretha,K Rebecca,...
All land plants we consume originate from algae. New species of algae are discovered every year. They are incredibly important because they are the primary plant in both salt and fresh water aquatic environments. The study of algae is called phycology, which is a subdiscipline of botany. Algae ...
Algae are not plants, animals or fungi. They belong to Kingdom Protista, a diverse group of single-celled eukaryotes. Protists have their own kingdom because many species share some characteristics of plants, animals or fungi. Algae belong to the group of plant-like protists. They are autot...
