Final answer:
Gymnosperms and angiosperms are two groups of seed plants that differ in their reproductive structures, fertilization process, and pollination methods. Gymnosperms have exposed bracts of the female cone, while angiosperms have an enclosed ovule in the ovary. Double fertilization occurs in angiosperms but not in gymnosperms.
Step-by-step explanation:
Gymnosperms and angiosperms are two groups of seed plants that differ in several ways. Angiosperms have flowers and their female gametophyte is enclosed within an ovule in the ovary, while gymnosperms have exposed bracts of the female cone. Angiosperms undergo double fertilization, which is absent in gymnosperms.
Gymnosperms have separate male and female gametophyte structures on cones, whereas in angiosperms, they are part of the flower. Additionally, wind plays a major role in pollination in gymnosperms. An example of a gymnosperm is a conifer, such as a pine tree, while an example of an angiosperm is a flowering plant like an orchid.
