Answer: B. Vascular tissue and seeds.
Gymnosperms and angiosperms both have vascular tissues that exist to function specifically in the transportation and distribution of water, organic compounds, minerals, etc. throughout the plant.
Whether it’s hidden within the fruit (like in angiosperms like palm nuts), or on the outside of the fruit (like strawberries and coniferous plants), both gymnosperms and angiosperms have seeds.
In plants, the vascular system functions, in the same way, the circulatory system functions in humans and animals, and in plants, this highly specialized transport system is made possible by the action of the xylem and the phloem.
