| 41. | The common name refers to the elongated horn-like structure, which is the sporophyte.
|
| 42. | The sporophyte of most hornworts are also photosynthetic, which is not the case with liverworts.
|
| 43. | Juvenile and dormant sporophytes can also be hidden in the soil for long periods of time.
|
| 44. | This means that new sporophytes can usually grow from the gametophyte formed from a single spore.
|
| 45. | Fertilisation follows and the zygote develops, settles and grows directly into the diploid sporophyte plant.
|
| 46. | In bryophytes, the sporophyte is always unbranched and remains nutritionally dependent on its parent gametophyte.
|
| 47. | The species has a chromosome number of 144 in the sporophyte, indicating an allotetraploid origin.
|
| 48. | When these diploid spores fertilized one another, they formed allotetraploid zygotes that grew into sporophytes.
|
| 49. | The species has a chromosome number of 144 ( 2 ?72 ) in the sporophyte.
|
| 50. | A mature animal is diploid and so is, in one sense, equivalent to a sporophyte.
