| 1. | These hypothetical hereditary units were similar to Darwin's gemmules.
|
| 2. | There were gemmules for hands and feet, not for whole organisms.

| 3. | Methods of asexual reproduction include both budding and the formation of gemmules.
|
| 4. | There may be gemmules near the base of the sponge.
|
| 5. | Gemmules are found in the freshwater family Spongellidae.
|
| 6. | The spire shows a peripheral cord with gemmules.
|
| 7. | Some gemmules remained dormant for generations, whereas others were routinely carried by all offspring.
|
| 8. | Freshwater gemmules may also include phytosynthesizing symbionts.
|
| 9. | Gemmules from the same species but different individuals can join forces to form one sponge.
|
| 10. | As he put it, some aspects of the external environment could modify the inheritable gemmules.
