[Campbell Biology P.695] Which of the following pairs correctly matches a structure/cell wit... | Practice Question

Which of the following pairs correctly matches a structure/cell with its ploidy level in the angiosperm life cycle as described and illustrated?

  • A: Microsporocyte: n
  • B: Megaspore: 2n
  • C: Embryo: 2n
  • D: Endosperm: 2n

Explanation

The diagram and text indicate that the sporophyte plant, microsporocytes, megasporangium, megasporocytes, zygote, embryo, and seed coat are all diploid 2n . The microspores, megaspores, male gametophyte, female gametophyte, generative cell, tube cell, egg cell, and sperm nuclei are haploid n . The endosperm is typically triploid 3n as a result of double fertilization.
