Answer 3

http://en.wikipedia.org/wiki/Alternation_of_generations
Alternation of generations occurs in almost all multicellular red and green algae, both freshwater forms (such as Cladophora) and seaweeds (such as Ulva). In most, the generations are homomorphic (isomorphic) and free-living. Some species of red algae have a complex triphasic alternation of generations, in which there is a gametophyte phase and two distinct sporophyte phases. For further information, see Red algae: Reproduction.

Answer 4

The red algae, or Rhodophyta
all brown algae have a life cycle with an alternation between haploid and diploid forms.
