| 1. | The plant body of a hornwort is a haploid gametophyte stage.
|
| 2. | In plants, oogenesis occurs inside the female gametophyte via mitosis.
|
| 3. | The longer lived, more prominent autotrophic plant is the gametophyte.
|
| 4. | All species are dioicous, with separate male and female gametophytes.
|
| 5. | Gametophytes which produce egg and sperm on separate plants are termed Dioicous.
|
| 6. | However, not all heteromorphic gametophytes come from heterosporous plants.
|
| 7. | The gametophyte becomes a food storage tissue in the seed.
|
| 8. | The haploid spores germinate and grow into a haploid gametophyte.
|
| 9. | The nutrition of the gametophyte appears to be endophytic fungi.
|
| 10. | Since moss gametophytes are autotrophic they require enough sunlight to perform photosynthesis.
