Blog post #7 Seth Nolan

This a picture of a brassica flower. the pictures underneath show the function of the flower under magnification.

This is a picture of an anther with stigma on it. the anther is the male reproductive system it holds pollen/sperm cells and the  stigma is the female reproductive system. The anther help pollinate by rubbing is pollen on passing bees.
This part of the flower is called the stigma. On a plant, the stigma is the site where the germination of the pollen grains occur.Along with the style and ovary, the stigma is part of the flower's structure called the pistil.
This is the ovule.  Each ovule is attached by its base to the stalk  that bears itplant structure that develops into a seed when fertilized.  A small opening  in the integuments at the apex of the ovule permits the pollen tube to enter and discharge its sperm nuclei into the embryo sac, a large oval cell in which fertilization and development occur.


this is a closs up of the pollen in our flower
