Based on the angiosperm life cycle shown, where would the most mitotic divisions primarily occur?

  • A: During the formation of microspores from microsporocytes.
  • B: During the development of the female gametophyte from a megaspore.
  • C: During the development of the embryo and subsequent growth into a mature sporophyte.
  • D: During the formation of sperm from the generative cell.

Explanation

Extensive mitotic divisions are required for the growth of the zygote into an embryo, and then the germination of the seed to form a large, multicellular sporophyte the mature plant with roots, stems, and leaves. This represents the vast majority of cell divisions in the angiosperm life cycle.
