[3][6] Algae constitute a paraphyletic and polyphyletic group‚[3] as they do not include all the descendants of the last universal ancestor nor do they all descend from a common algal ancestor‚ although their plastids seem to have a single origin.[1] Diatoms are also examples of algae. Algae exhibit a wide range of reproductive strategies‚ from simple‚ asexual cell division to complex forms of sexual reproduction.[7] Algae lack the various structures that characterize land plants‚ such as the leaf-like
