Question

How are angiosperms distinguished from other vascular plants?

Answer 1

Angiosperms are flowering plants.  They use flowers to make their seeds.

Answer 2

There are three groups of Vascular plant = Chronologically=

1 ) Pteridophytes

2 ) Gymnosperms  and

3 ) Angiosperms

Out of these three, Pteridophytes  are flowerless and seedless and angiosperms are flowering and seed bearing  .

That is how you can distinguish Angiosperms from them.

That leaves Gymnosperms and Angiosperms for distinction =

Both produce seeds but only Angiosperms produce fruits as well !

These are easily discernible distinctions . There are many more . But for that you work on your own
