| Fertilization occurs in the mesenchyme and the zygotes develop into ciliated larvae. |
| Conjugation frequencies were calculated by dividing the number of zygotes by the total number of cells present. |
| Those 10 frozen little 16 or 32 cell zygotes will never be used for anything else. |
| The zygotes of the fucoid brown algae have long been studied by developmental biologists in an effort to understand how cellular polarity arises. |
| Ceratopteris spores, like fucoid zygotes, divide unequally to produce a small rhizoid cell and a larger cell that develops into the thallus. |
| In most diplonts, mitosis occurs only in the diploid phase, i.e. gametes usually form quickly and fuse to produce diploid zygotes. |
