Here's a breakdown:

* Sporophyte: The diploid (2n) generation of a plant's life cycle. It's the dominant generation in non-flowering plants (like ferns, mosses, and liverworts).

* Spore: A single-celled reproductive unit that can develop into a new plant without fertilization.

The sporophyte produces spores through a process called meiosis, which reduces the chromosome number from diploid to haploid (n). These spores then germinate and develop into gametophytes, which are the haploid generation responsible for producing gametes (sperm and egg).
