gametophytes
gametophyte stage
Plants produce spores during the gametophyte, or haploid, stages. Spores are the sex cells for the plant. The spores will then germinate and produce new plants.
Ferns produce spores as their means of procreation as other plants produce seeds.

flowering plants don't produce spores - they produce pollen

spores
Heterosporous plants are those that produce two types of spores that differ in size and sex. In particular, they produce two morphologically distinct types of sporangia (megasporangia and microsporangia) that create two distinct types of spores (megaspores and microspores). The spores then develop into separate male and female gametophytes. They are different from homosporous plants in which the sporophyte produce a single type of sporangium and then a single type of mother spore cell.
The gametophyte stage
Through the process of meiosis.
No plants release oxygen
Spores are produced during sporogenesis, which is found specifically in plants, algae and fungi. No animals currently produce spores as a method of reproduction.
