Answer:
Flowers and fruits
Step-by-step explanation:
The plants which possess vascular tissues are known as the vascular plants like the pteridophytes, gymnosperms and angiosperms and the plants which do not contain the vascular tissues are known as nonvascular plants like the thallophytes and the bryophytes.
In the given features all the provided options are present in the vascular plants and absent in the non-vascular plants but flowers and fruits are the option which is found in some vascular plants especially in the plants of the angiosperm families and are absent in non-vascular plants also.
Thus, Flowers and fruits are the correct answer.
