Question

are bryophyte spores part of the sporophyte or gametophyte generation? how about fern spores?

Answer 1

↪ Bryophytes spores are a part of gametophyte generation.

↪ Pteridophytes includes ferns.

Hence, Ferns are a part of sporophytic generation.

Answer 2

In the Bryophites, the sporophyte generation is short-lived. It comprises a capsule which produces spores by meiosis and a stalk which holds this aloft the gametophyte. The spores once released are dispersed by air currents and, once they settle somewhere moist, germinate.

The defining features of bryophytes are:

• Their life cycles are dominated by the gametophyte stage.
• Their sporophytes are unbranched.

All vascular plants feature an alternation of generations within their life cycle:

• The sporophyte generation
• The gametophyte generation

Fern is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients, in having branched stems and in having life cycles in which the sporophyte is the dominant phase.

The life cycle of ferns is different from other land plants as both the gametophyte and the sporophyte phases are free living.
