Which of the following is the correct sequence of events in a pollen sac?
A) sporangia → meiosis → two haploid cells → meiosis → two pollen grains per cell
B) pollen grain → meiosis → two generative cells → two tube cells per pollen grain
C) two haploid cells → meiosis → generative cell → tube cell-fertilization → pollen grain
D) pollen grain → mitosis → microspores → meiosis → generative cell plus tube cell
E) microsporocyte → meiosis → microspores → mitosis → two haploid cells per pollen grain

Question

Quizplus · Accepted Answer

In a pollen sac, the correct sequence starts with a microsporocyte undergoing meiosis to produce microspores. Each microspore then undergoes mitosis to form two haploid cells per pollen grain, typically a generative cell and a tube cell.
