Question

Which phase in the angiosperm life cycle is diploid in chromosome number and begins with the zygote?

Options

• Gametophytic phase

• Gametic phase

• Spore phase

• Sporophytic phase

Answer 1

The sporophytic phase is the diploid (2n) phase that begins with the zygote and includes the embryo, seedling, and mature flowering plant. This is the dominant, independent, and long-lived phase in angiosperms, producing spores through meiosis.
