| 41. | The condition of having separate sporophyte and gametophyte plants is call alternation of generations.
|
| 42. | The gametophytes produce male ( antheridium ), and female ( archegonium ) gametes.
|
| 43. | They later germinate into heart-shaped gametophytes.
|
| 44. | No haploid spores capable of dividing are produced, so neither is a haploid gametophyte.
|
| 45. | In dioicous mosses, male and female sex organs are borne on different gametophyte plants.
|
| 46. | These undergo mitosis to form male gametophytes, each of which contains two haploid cells.
|
| 47. | Mature sporophytes remain attached to the gametophyte.
|
| 48. | The sporophyte remains small and dependent on the parent gametophyte for its entire brief life.
|
| 49. | The resulting meiospores develop into a gametophyte.
|
| 50. | The sporophyte produces spores which develop into free-living male and female gametophyte plants.
