Question

explain the pollination and double fertilization that take place in the Datura​

Answer 1

Answer:

Self-pollination occurs when anthers and stigmas come into contact, both as the flowers open and as the corolla is shed the next day (Elle and Hare, 2002), as well as when visitors transfer pollen among flowers on the same plant.

Double fertilization is a complex fertilization mechanism of flowering plants (angiosperms). This process involves the joining of a female gametophyte (megagametophyte, also called the embryo sac) with two male gametes (sperm). ... The pollen tube proceeds to release the two sperm in the megagametophyte.
