A scientist observes a new angiosperm species and determines it undergoes typical sexual reproduction. Which of the following sequences of events is most likely to occur in this plant?

  • A: Pollen grain transferred to stigma → Pollen tube delivers sperm to ovule → Ovule develops into fruit → Fruit disperses seeds.
  • B: Anther produces pollen → Pollination → Fertilization of egg by sperm → Ovary becomes fruit → Seed germination into plant.
  • C: Ovary develops into fruit → Fertilization → Ovule becomes seed → Seed dispersal.
  • D: Meiosis produces diploid embryo → Pollen grain transferred → Ovule becomes fruit → Plant growth.

Explanation

The correct sequence of events in angiosperm sexual reproduction involves pollen production in the anther, followed by pollination pollen transfer to stigma , fertilization of the egg within the ovule by sperm from the pollen tube, the ovary developing into a fruit, and the subsequent germination of the dispersed seed into a new plant.
