Step 1
Angiosperms and gymnosperms are both seed-bearing plants with a few similarities.
Step 2:
The vascular system is common for the both of them, consisting of conjoint and vascular bundles (open and collateral). The ovules of both angiosperms and gymnosperms develop into seeds.
Step 3
a) Angiosperms are flowering plants, and include grasses, herbs, shrubs and most deciduous trees, while (b) gymnosperms are conifers. Both produce seeds but have different reproductive strategies.
Final answer
seeds
