Plants that have both female and male sexual organs or flowers called Monoecious plants. These male and female parts are located at different locations on the plant. Example: Cucurbit, Chara and Coconut. What animals are dioecious? Monoecious: Earthworms, slugs, jellyfish and planarians are exa...
But moon jellyfish have a special genetic toolkit: an elite arsenal of genes that activate during their medusa stage but are absent in anthozoans. Devoid of a jellyfishstage, corals and anemones lack the genes to grow certain organs and tissues, such as eyes and specialized swimming muscles....
