- A Two genetically identical daughter cells of exactly equal size and identical developmental fate each time in routine practice
- B A small apical cell (embryo proper) and large basal cell (suspensor that attaches to seed coat and nourishes embryo)
- C Endosperm tissue directly, largely bypassing the usual formation of the embryo proper itself overall in most cases
- D A largely formed multicellular embryo supposedly produced within just a single cell division event under typical conditions
Correct answer: B. A small apical cell (embryo proper) and large basal cell (suspensor that attaches to seed coat and nourishes embryo)
Explanation: Zygote first division: asymmetric. Small apical cell → embryo proper (shoot/root meristems, cotyledons). Large basal cell → suspensor (anchors embryo, delivers nutrients).
