FoundationWhat two products result directly from double fertilization in angiosperms?
Need a small nudge?

One sperm joins the egg; the other joins the central cell nuclei.

UnderstandingAfter fertilization in a typical flowering plant, which developmental mapping is usually correct?
Need a small nudge?

Separate the structure containing the embryo from the structure surrounding the seed or seeds.

ApplicationA mutation prevents the second sperm from fusing with the central cell but allows sperm–egg fusion. Which structure is most directly missing or abnormal?
Need a small nudge?

Match each sperm fusion to its direct product.

InterpretationPollen has reached a compatible stigma, but no sperm nuclei reach the ovule. Which statement is best?
Need a small nudge?

Pollen arrival and gamete fusion are separate gates.

ConnectionWhich sequence correctly orders the major events from pollen arrival to seed and fruit development in a typical angiosperm?
Need a small nudge?

Begin with transfer to the stigma and end with post-fertilization development.
