| 11. | They germinate and multiply into vegetative cells in the colon upon exposure to bile acids.
|
| 12. | Some of the vegetative cells of " Ulothrix " are converted into thick walled akinetes.
|
| 13. | Upon exposure to bile acids, they germinate and multiply into vegetative cells in the colon.
|
| 14. | When the environment is favorable, the zygospore germinates, meiosis occurs, and haploid vegetative cells are released.
|
| 15. | Endospores are resistant to most agents that would normally kill the vegetative cells they formed from.
|
| 16. | The recombined haploid nuclei appear among vegetative cells, which differ genetically from those of the parent mycelium.
|
| 17. | Sporulation is now complete, and the mature endospore will be released when the surrounding vegetative cell is degraded.
|
| 18. | The copper alloys significantly reduced the viability of both " C . difficile " spores and vegetative cells.
|
| 19. | Reproductive cells at first like the vegetative cells, later with a more massive chloroplast that eventually contains several pyrenoids.
|
| 20. | The sexual program of Gonium is induced by nitrogen deprivation where each vegetative cell within the colony differentiates in gametes.
