FLOWER DISSECTION



My favorite experiment is the flower dissection. This experiment was about cutting a flower to observe the different parts with the microscope.



 Equipment or material

For this experiment we need: a microscope, scissors, forceps, a knife and a flower.

 Procedure:

 1-Carefully examine your flower and compare it to the diagram in the previous page.

 2-Carefully with the forceps, remove all the petals and sepals.

 3-Pull up a stamen with the forceps and put it in a slide to observe it with the microscope. Try to notice small pollen grains.

 4-Carefully remove the pistil from the flower. Make an up-and-down cut with the scalpel to it.

 5-Cut the stamen in a half.
Thanks you for attention!
