sporophyte?

quote:

In plants that undergo alternation of generations, a sporophyte is the structure, or phase of life, that contains a total complement of chromosomes:

The sporophyte produces spores, in a process called meiosis. These spores develop into a gametophyte. These spores and the resulting gametophyte have only half of the total complement of chromosomes.
The gametophyte produces male or female gametes (or both), in a process called mitosis. The fusion of male and female gametes produces a zygote which develops into the sporophyte.
