Answer

  1. It is because the filaments of anthers are united in two bundles. Nine out of ten stamens in a pea plant form a staminal tube. The tenth is free.
  2. Ray florets of sunflower are described as neuters because both male and female reproductive structures are lacking.
  3. Sepals of the salvia are petaloid as 3 sepals are red in colour and united as petals. Therefore, they are not differentiated from the petals.
