The presence of seeds and vascular tissue
They both produce seeds. Gymnosperm means "naked seed" as the seeds are not enclosed but rather in the cones or on the tip of the branch. The angiosperms have enclosed seeds, as inside a fruit or berry. They both produce secondary wood and bark (xylem and phloem) by cell division in the cambium.
Angiosperms and Gymnosperms branch from a single common ancestor.
Yes, they are. An example of a gymnosperm would be a pine tree, for example.
they posses flowers as their sporophytes' sexual organs which enable pollination
The phylum for common marigolds is angiosperms. Angiosperms are the flowering plants.
they both producee seeds!
Angiosperms.
Common ancestors are the ancestors you and a relative of yours have in common. For example, your first cousin and you have the same grandparents. The grandparents are your and your first cousins common ancestors.

A common grape is an angiosperm, (therefore is a dicot).
The principle that all species were derived from common ancestors is known as Common descent.
The most common similarity is definitely SPERM!!
