Mist Flower, Ironweed and Photosynthesis

Today in AP Biology was photosynthesis day ... Light Reactions and the Light-Independent Reactions ... C3, C4 and CAM ...  We finished the class with sample questions from our Campbell Test Bank ... still lots of students not doing their questions before class voluntarily.  A lesson soon to be learned!

Checking problems today and tomorrow in Introduction to Computer Programming as we begin to wrap up Karel programming with the final two problems ... Karel can Add and Mission Impossible.

Stayed after school late to work and was hoping it would rain but, no rain in Holland.  Fall wildflowers are in full bloom, especially wingstem.  Below are close ups of ironweed (some ironweed plants I have seen this year are over ten feet tall) and mist flower (wild ageratum).

The two Monarch caterpillars I have been watching have crawled off and have pupated into a chrysalis ... or was eaten.  I have not been able to locate them but will keep looking.
