| 120476346 | stipe | stemlike structure of a seaweed | |
| 120476347 | blades | leaflike structure of a seaweed that provides most of the surface area for photosynthesis | |
| 120476348 | alternation of generations | life cycle in which there is both a multicellular diploid form, the sporophyte, and a multicellular haploid form, the gametophyte; characteristic of plants and some algae | |
| 120476349 | heteromorphic | condition in life cycle of all living plants and certain algae in which the sporophyte and gametophyte differ in morphology | |
| 120476350 | isomorphic | referring to alternation of generations in plants and certain algae in which the sporophytes and gametophytes look alike, although they differ in chromosome number | |
