Flower Dissection

Awww... isn't this sweet!!! I got flowers!!!!
Actually I bought them myself.
And I can't wait to chop them up.
It's flower dissection day!  Whooohooo!

You will have a three part blog post for this assignment - flower structure, pollination & angiosperm classification.



Flower Dissection

Flower Structure:
Identify, take pictures & label all of the following parts of the flower – which are male parts and which are female?

·      Anther
·      Stigma
·      Petals
·      Style
·      Ovary
·      Filament
·      Sepals

Using the scalpel, cut the ovary in half to see the ovules inside (use dissecting microscope if needed).

Find the pollen and try to create a slide so that you can see the pollen magnified.  Describe what you are able to see.

Pollination:
What is pollination?  What structures are involved?  What are the differences between self-pollination and cross-pollination and what are the benefits of each?

Angiosperm classification:
What type of flower are you dissecting?  Take pictures and describe all the evidence that helped you make your classification.
