Gymnosperms and angiosperms have the following in common except
Artist 52 [7]

Answer:  c.ovaries.

Explanation:

Gymnosperms and angiosperms are plants with seeds, where the great advantage present in both groups is the presence of pollen grain (which is the male gametophyte), which eliminates the need for water during reproduction.

In gymnosperms, the gametophyte grows in structures called strobiles or cones. The male gametophyte is released in the wind and, with lucky, landing in a female strobile and germinates. The female gametophyte develops within the strobile leaf, waiting for the pollen grain.

On the other hand, the most evolutionarily successful is the angiosperm group, the plants with flower and fruit. Flowers were decisive in animal pollination. The flower contains the eggs and can be grouped in inflorescences or solitary. The flowers have structures to attract pollinators, such as beautiful colored petals.
