1. This is the Anthers  and stigma of the flowers. The Anthers are where the haploid gametophtyes Are Produced. The stigma is the sticky portion at the top of the style where pollen grains frequently. The Anthers are supported by the stamen.

2. This Is Nector that the plants make so that pollinators or bees will be attracted to it. The Nector tastes like sugar water and that is why the bees go back to feed of of it.

3. This is the ovary of the flower. The Ovary of the flower is formed by the carpels. The ovary contains one or more ovules where female gametophytes are produced.

4. these are the insides of the ovaries. The Circles in the ovaries are the haploid cells. The Haploid cells only contains a single set of chromosomes and one single set of genes. 

5. This was what the flower looked like before it was taken apart.

Fertilization of flowering plant occurs in a process called pollination. flower's center contains long, thin filaments, topped by small oblong anthers. Together, the filaments and anthers are called stamen. Each anther houses four pollen sacs, which produce pollen. The pollen sacs contain microspore mother cells, or MMCs. Each pollen sac will produce eight sperm cells from the MMCs, or pollen grains. When the pollen grains in the sacs become ripe, the anthers burst open, releasing the sticky pollen onto the stamen. This bursting of the pollen sacs, called dehiscence, sometimes happens with enough force that the pollen propells forcefully out of the flower and onto the wind, which carries it to other flowers.The bright colors of the petals lure insects, where they alight and partake of the flower's nectar. Glands located at the flower's base produce nectar. To reach the nectar, insects must climb all the way into the flower itself. During the process, pollen grains located on the anthers either become stuck to the insect's feet (where they are transferred to another flower, in a process called cross-pollination) or moved from the stamen to the pistil of the same flower (self-pollination). This occurs in many instances, because of the pistil's location in the center of the flower surrounded by the stamen.
