| 1. | The two centrioles in the centrosome are tied to one another.
|
| 2. | The sperm contributes a pronucleus and a centriole to the egg.
|
| 3. | First, the connection between the two parental centrioles is destroyed.
|
| 4. | The mother centriole has radiating appendages at the proximal end.
|
| 5. | Centrioles can act as markers for MTOCs in the cell.
|
| 6. | Free microtubules elongate the initial cylindrical structure of procentrioles to form centrioles.
|
| 7. | Only one procentriole forms next to each centriole during a cell cycle.
|
| 8. | Glaucophytes have mitochondria with flat cristae, and undergo open mitosis without centrioles.
|
| 9. | Furthermore, it increases the stability of growing centrioles.
|
| 10. | The cells of the Archaeplastida typically lack centrioles and have mitochondria with flat cristae.
