Blogpost 10

This is a brassica oleracea flower, its petals are yellow.
Inside of it is where all the reproduction happens.
This is the male part of the flower, known as the stamen. It has 
a filament coming up from the base of the flower. At the 
tip of each filament is an anther, where
 meiosis takes place, producing pollen grains. It produces
 male haploid gametophytes.
This is the female part of the flower known as carpel, it is the 
innermost floral part. It consists a stalk called a style. It has a sticky tip called stigma, in the sticky tip is where the pollen grain gets stuck.
Further in the dissection, we are exposed nothing left but the ovary.
The ovary is the green tube and in it there are small green ovules.

 This is a picture of the whole Brassica olereacea flower from one of the plants in the garden.  This type of flower goes through meiosis for reproduction. Not every plant goes through meiosis but this particular flower does. Meiosis is the process f which the number of chromosomes per cell is cut in half through the separation of homologs chromosomes in a diploid cell.
 This image shows the anthers. An anther is the flower structure where the haploid male gametophytes are being produced. Anthers are at the tip of each filament. A filament is a long thin stalk that helps support the anther. An anther is an oval sac where meiosis takes place.
 In this image the carpel was cut in half. The little circles inside are called ovules. An ovule is a structure in the seed cones where the female gametophytes are developed. These are unfertilized eggs waiting for meiosis to begin so that the flower reproduces.
Here is the carpel of the flower.  The carpel is the innermost part of the entire flower that produces the female gametophytes. Carpels are also known as pistils. Each carpel forms an ovary which contains one or even more ovules where the female gametophytes are made.
