Answer the following question given this paragraph: Seeds and Pollen as an Evolutionary Adaptation to Dry Land Unlike bryophyte and fern spores (which are haploid cells dependent on moisture for rapid development of gametophytes), seeds contain a diploid embryo that will germinate into a sporophyte. Storage tissue to sustain growth and a protective coat give seeds their superior evolutionary advantage. Several layers of hardened tissue prevent desiccation, and free reproduction from the need for a constant supply of water. Furthermore, seeds remain in a state of dormancyinduced by desiccation and the hormone abscisic aciduntil conditions for growth become favorable. Whether blown by the. Q: Unlike bryophyte and fern spores (which are haploid cells dependent on moisture for rapid development of gametophytes), seeds contain a diploid embryo that will germinate into what? Choices: - sperm - gametophyte - ovary - sporophyte A:
sporophyte
