Asunflower is an angiosperm, and a gingko is a gymnosperm. which best describes the life cycles of sunflowers and gingkoes? i. both the sunflower and gingko have seeds. ii. both the sunflower and gingko have cones. iii. the seeds of sunflowers are protected by a fruit; the seeds of gingkoes are not protected by a fruit. iv. the life cycle of sunflowers involves double fertilization; the life cycle of gingkoes involves single fertilization. i, ii, and iii i, iii, and iv ii, iii, and iv i, ii, and iv

The correct answer is option I, II and IV.

An angiosperm refers to a plant, which exhibits flowers and generates seeds enveloped within a carpel. The angiosperms are a large group and involve shrubs, herbaceous plants, the majority of trees, and grasses. A gymnosperm refers to a plant, which has seeds unprotected by a fruit or an ovary. The gymnosperms comprise of conifers, ginkgo, and cycads.

In the given case, both the sunflower (angiosperm) and gingko (gymnosperm) are seed-producing plants. However, the seeds of a sunflower are safeguarded by a flower or a fruit, while in case of Gingkoes they are not. Also, sunflowers include double fertilization, while the Gingkoes involve only a single fertilization.

the correct answer is b
