Blog Post 7




  





     The lab that we did was about dissecting the Brassica flower and naming some of the plant's parts and what they do for the flower.  The dissection was easier then I thought and it was very interesting lab to do.
 
     This image shows of the stem in the microscope.  The stem is where water flows up and down the plant and where the muscle of the structure is.  The stem is more of the body of the plant because it is attached to the petals, stigma, and the roots.


                                                                     



     The top part of the image shows the stigma in the lens of the microscope.  The stigma is the part of the plant that produces the pollen.  



     The bottom part of the image shows the pistil in the microscope.  The pistil is where an ovary is fertilized by pollen which forms a zygote because each egg and pollen grain is a haploid gamete. Once they meet they combine their haploid cells to create a diploid zygote. In many plants, the embryo created by this process of fertilization is surrounded by a fleshy structure that is the ovary itself.
