Some euglenoids are autotrophic while others are heterotrophic. what means a genetic recombination in bacteria that requires a direct link between donor and recipient cells? Red algae, from the phylum Rhodophyta (from the Greek rhodos, meaning "red"), are named for their reddish color because of their pigment phycoerythrin. Algae can be unicellular or as large as a tree like the giant sea kelp. Union of male and female gametes (n) forms a zygote (2n) that grows into a diploid sporophyte. Various types of asexual reproduction are common in algae, but algae also reproduce sexually, forming genetically diverse gametes by meiosis, then joining two gametes from two different individuals to create a new individual. be membranous like, Asexual reproduction -In asexual Analytical cookies are used to understand how visitors interact with the website.
