Here's a breakdown:

* Sporic Life Cycle: This life cycle alternates between a haploid (n) gametophyte generation and a diploid (2n) sporophyte generation.

* Sporophyte: The sporophyte is the diploid generation that produces spores through meiosis.

* Mitosis: Mitosis is a type of cell division that produces two identical daughter cells from a single parent cell.

In the sporophyte generation:

* Mitosis is used for growth and development of the sporophyte plant.

* Meiosis is used to produce haploid spores, which will then develop into the gametophyte generation.

Gametophyte:

* The gametophyte generation is haploid and produces gametes (sperm and egg) through mitosis.

To summarize:

* Mitosis is responsible for the growth and development of both the sporophyte and gametophyte generations.

* Meiosis is specific to the sporophyte generation for the production of spores.
