Anatomy Green Flat blade Two cell layers thick Sporophyte and gametophyte look the same (isomorphic) http://omp.gso.uri.edu/ompweb/doee/biota/algae/chloro/ulva.htm http://www.cryptogamicbotany.com/images/oa_chloro/ulva_lactuca_01_05_09_a_324x550.jpg
Life Cycle Isomorphic Alternation of Generations: gametophytes sporophytes have the same form Anisogamous: gametes of unequal size http://cronodon.com/biotech/algal_bodies.html

Recipes Sea Lettuce Soup 4 cups chicken stock 2 sheets Ulva 2 eggs Salt and pepper ½ tsp sesame oil 1 or 2 green scallions Bring stock to a boil. Add sea lettuce and stir. When sea lettuce is soft, stir in well- beaten eggs and boil for a few seconds then remove from heat. Add salt and pepper to taste. Add sesame oil, garnish with onion, and serve. (Deane, 2013) Toasted Sea Lettuce 6 sheets Ulva ½ tsp Salt 1 ½ tablespoon sesame oil Mix salt and sesame oil and rub a thin coat on sea lettuce. Lay 6 sheets on top of one another, roll them up and let them marinade for 5 minutes. Unroll and cook each sheet separately in a hot pan over low heat until crisp. Cut sheet into smaller pieces and serve with hot rice.
