According to Figure 30.4, which of the following structures is correctly matched with its ploidy level?

  • A: Megasporangium (n)
  • B: Female gametophyte (2n)
  • C: Pollen grain (n)
  • D: Embryo (n)

Explanation

The key in Figure 30.4 clearly indicates "Haploid n " and "Diploid 2n ". By inspecting the labels in the diagram: Megasporangium is labeled 2n , Female gametophyte is shown deriving from megaspore n and is therefore n , Pollen grain is explicitly labeled n , and Embryo is labeled 2n . Therefore, only "Pollen grain n " is correctly matched.
