Answer:

1. Gametophyte

2. Sporophyte

Explanation:

The life cycle of the Liverwort and mosses which are placed in the Bryophytes is divided into the sporophytic and the gametophytic phase.

Gametophyte

The gametophyte is the dominant phase of the life cycle which appears like the ribbon, green in color and posses the gamete producing structure- the antheridium and the archegonium.  

Sporophyte

The gametes fuse to form the embryo and from that is produced the sporophyte structure, an umbrella-like structure called a sporangium. This sporangium produces the spores which later will form the gametophyte.

That would be A. Produces reproductive organs which produce a zygote.

Zygotes grow into the sporophyte(diploid), spores grow into the gametophyte(haploid).

Sporophyte produces haploid spores through meiosis, gametophyte produces gametes through mitosis.
