Neither exactly. Angiosperms produce flowers and fruit (drupes, berries,
etc). Gymnosperms produce cones and naked seeds in what is their equivalent
of a flower, a pistillate strobilus, however this is not recognized as a
true flower And then there are the spore-bearing plants which produce
neither flowers, fruits or seeds.

Your statement may be perhaps better phrased as " all plants produce either
pollen or spores".

I'm gonna say false, though its been so many years since I've read about
the wide array of plant reproduction tactics that I probably couldn't
offer a coherent thesis now. I may get some of this wrong, but what comes
to mind: Algae reproduction is fantastically diverse. While many algaes
produce spores or even mobile zoospores resembling animal planktons,
others reproduce (sexually) by conjugation & division, or (asexually) by
mitosis, & some multicellular algaes merely fragment & grow new plants
from their many pieces. Some algaes use multiple reproduction tactics, but
production of spores isn't shared by all species of algaes. Some algaes
more resemble bacteria than they do higher plants.

'Higher plants' may be the key here. Technically, the Kingdom Plantae
excludes bacteria, algae and fungi (each comprises their own kingdom -
Monera [bacteria and blue-green algae], Prostista [all other algae and
protozoans] and Fungi [the mushrooms, molds and other fungi]). The
requirement for inclusion in the Kingdom Plantae is that the organism be
multicelled, be a eucaryote (the cell walls are separated by a membrane,
typically cellulose) and be able to manufacture its own food.

But the idea is there - the statement is more false than true. There is not
much in the world of plants that can be simplified that succinctly.

False.

All plants produce reproductive spores of one type or another.

Flowering plants produce spores also.

However, the megaspores and microspores are highly modified. The megaspores
become seeds while the microspores become pollen.
