Which of the following accurately describes the life cycle of most gymnosperms?

A. Seed cones contain ovules.

B. Germinated seeds are haploid.

C. A pollen tube is used to prevent the fertilization process.

D. Pollen grains undergo meiosis to form egg cells.

A

Answer: The correct answer is A. Seed cones contain ovules.

The Gymnosperms are plants whose seeds are not covered in an ovary. They are seed-producing plants with conifers and cycads being two popular gymnosperms. The seeds of gymnosperms are not protected by outer coverings and they neither bear flowers nor fruits. In their life cycle, the gametophyte stage of gymnosperms occurs in a cone. The male gametophytes are few cells located in the pollen while the female gametophytes produce eggs in the ovule.
