Can you please explain fertilization for me? I am a bit confused. After the pollen tube travels down the style, does it go in the ovary and join with the ovule (which contains the female reproductive cells) and creates a seed?

  1. Slight correction on the first answer.  The pollen tube grows through the style to the ovule.  In the tube, two sperm nuclei are formed.  One sperm nucleus fertilizes the egg cell in the ovule.  The other fertilizes to polar nuclei forming the endosperm.  This process is called double fertilization.  In some plants the endosperm persists and is found in the seed.  In most, the endosperm disappears replaced by cotyledons.  Coconut milk is liquid endosperm!


  2. Everything you said was correct except the ovary forms the fruit.

    Basically Pollen is created from the anthers (male part) and brought to a female flower. The pollen that lands on the stigma sticks there because it has a sticky substance over it. Upon landing on it the pollen grains germinate to s***n. This travels down the style (tube-like structure the ovary to the stigma) to the ovary and wraps around the ovary and enters through the micropyle into the ovule where it fertilizes it. After this the ovary basically swells and forms the fruit.
