• meiosis
• flower
• stamen
• pistil

Flowers with both reproductive organs are called ​ (a)   or "complete" flowers. In some species, certain flowers contain only ​ (b)   , while others contain only pistils. Flowers having only one reproductive organ are called "imperfect" or ​ (c)   flowers.

The stamen is composed of an ​ (a)   or filament. As a result of ​ (b)   the diploid cells of the anther produce ​ (c)   which contain ​ (d)   nuclei (n).

• anther
• meiosis,
• pollen grains
