Question

A sunflower is an angiosperm, and a gingko is a gymnosperm. Which best describes the life cycles of sunflowers and gingkoes?

Answer 1

Answer:

Both the sunflower and gingko have seeds.

 Both the sunflower and gingko have cones.

The life cycle of sunflowers involves double fertilization; the life cycle of ginkgoes involves single fertilization.

Explanation:

An angiosperm refers to plants which are flower bearing and usually bisexual. The angiosperms are a large group and include grasses, herbs, shrubs and trees. A gymnosperm refers to plants whose seeds are borne on the female cones and seeds are not enclosed in a fruit wall. The gymnosperms comprise of coniferales, cycadales and ginkgoales. Both the sunflower (angiosperm) and ginkgo (gymnosperm) are seed-producing plants. However, the seeds of a sunflower are enclosed by a flower or a fruit wall, while in case of Ginkgoales they are not. Also, sunflowers include double fertilization, while the Ginkgoales involve only a single fertilization.
