Flower #7

Angiosperms have to go through the procedure of pollination before being able to do any type of reproducing. Pollination happens with the male sex organs of the flower, on the anther which is connected to the end of the stamen. The pollen is then moved to the female sex organs of the plant. Pollen is transported by birds and insects like bees when they get the get what they need out of the flower. Wind is also a factor in pollination. So, the pollen will get to the pistil in the female sex organs, and will end at the stigma at the end of the pistil. The stigma then moves the pollen down a tube which is called the style which no goes down to the ovary.  Angiosperms contain both female and male sex organs on the same plant, so the same flower does not need anything else to undergo the process of sexual reproduction.

These images are the sections of the broccoli plant taken apart and was examined under a microscope. You are able to see where the organs are of the flower.
