Question

multiple choice question
after double fertilization, the ovule develops into a _______ that contains the endosperm and embryo.
o megaspore
gametophyte
o microspore
o seed

Explanation:

Double fertilization is a key process in angiosperms. After double fertilization, the ovule undergoes development. The zygote (from fertilization of egg and sperm) develops into an embryo, and the primary endosperm nucleus (from fertilization of polar nuclei and sperm) develops into endosperm. The ovule as a whole develops into a seed which encloses these two structures. A megaspore is an early - stage cell in the female gametophyte development. A gametophyte is a haploid stage in the plant life cycle (e.g., the embryo sac is part of the female gametophyte). A microspore is an early - stage cell in male gametophyte (pollen grain) development.

Answer:

seed
