What is a characteristic of the life cycle of gymnosperms?
The life cycle of a gymnosperm involves alternation of generations, with a dominant sporophyte in which the female gametophyte resides, and reduced gametophytes. All gymnosperms are heterosporous. The male and female reproductive organs can form in cones or strobili.
What is unique about angiosperms?
All angiosperms have stamens. … Angiosperms have much smaller female reproductive parts than non-flowering plants, allowing them to produce seeds more quickly. Angiosperms have carpels that enclose developing seeds that may turn into a fruit. A great advantage for angiosperms is the production of endosperm.
