Just Keep Marching

Within the AP Biology community there is a dreaded block of information fondly known as the "march of kingdoms." In order to complete the march of kingdoms, one must endure a relentless onslaught of knowledge. The topics of which are as broad ranging as archaea are from primates. Over the course of two weeks the brave soldiers of AP Biology will cover the ins and outs of most of the living world. In addition they will be asked to make connections with regard to evolution, form and function, and relation to human life. Friday they will finally take the test and probably breathe a collective sigh of relief. 

A snapshot of last week's action (3/12-3/16) is brought to you by Dipatri Farkas (he who is fond of the capital letter) and Morgan Travis.

Dipatri Begins: 

THIS WEEK WAS ALL ABOUT HOW THE LIFE OUTSIDE OF OUR COMFORTABLE, AIR-CONDITIONED LIFESTYLES WORK AND CAME TO BE.WE STARTED OFF WITH THE SIMPLE PROKARYOTES THAT LIVE ANY & EVERYWHERE: BACTERIA AND ARCHAEA. THE MAJOR DIFFERENCE BETWEEN THESE TWO ARE THE HABITATS IN WHICH THEY LIVE SEEING AS HOW ARCHAEA ONLY LIVE IN EXTREME CONDITIONS AND BACTERIA LIVE BASICALLY EVERYWHERE ELSE IMAGINABLE. WE PROGRESSED TO THE PROTISTS WHICH ARE ANY EUKARYOTES NOT CLASSIFIED AS AN ANIMAL, PLANT, OR FUNGUS. MAJOR TOPICS NEEDED FOR THEIR ORIGINS INCLUDE SECONDARY ENDOSYMBIOSIS AND THE COMPLEX MULTI-HOST LIFESTYLE SOME LEAD. THE NEXT FEW DAYS REQUIRED US TO LEARN ABOUT THE MANY ADAPTATIONS THAT PLANTS MUST HAVE DEVELOPED TO SURVIVE THE NON-AQUATIC ENVIRONMENT THEY WERE GOING TO CALL THEIR NEW HOME, SUCH AS: OBTAINING H2O FROM A DRY ENVIRONMENT, FERTILIZING WITHOUT THEIR ZYGOTES DRYING OUT, SPREADING SPERM WITH A LACK OF CONTINUOUS H20, ETCETERA. AND WE ALSO MUST NOW BE ABLE TO DIFFERENTIATE AN ANGIOSPERM FROM A GYMNOSPERM. TERRIBLE FACT: APPARENTLY ANYTHING THAT BEARS SEEDS IS A FRUIT, SUCH AS PEA PODS AND RICE, UNRAVELING THE VERY FOUNDATION OF MY UNDERSTANDING OF A VEGETABLE! THE LAST TOPIC OF THE WEEK WAS UNDERSTANDING THE DEVELOPMENT OF THAT FURRY STUFF THAT GROWS ON YOUR OLD BREAD. MANY CATEGORIES OF FUNGUS WERE DESCRIBED BUT THE ONE THING THAT INTRIGUED ME WAS THE PARASITIC ERGOT. IT GROWS ON RYE AND CAUSED AN EPIDEMIC OF 40,000 DEATHS BUT THE MOST IMPORTANT PART IS THAT IT CAN CAUSE TEMPORARY INSANITY! I THINK THAT's ALL I HAVE TO SAY

Morgan concludes:

This week in AP Biology was definitely that of many topics as we flew through chapters 27 through 31. Our main subjects we talked about were Protists, Plant diversity, Bacteria & Archaea and Fungi. Definitely the most interesting to me was plant diversity. It never occurred to me how plants colonized land and what challenges they faced in doing so. Whether it was how would they reproduce, feed, support themselves against gravity, and keep from drying out. We discussed these issues in class by going through each of the different issues and taking our best guess at what we thought could resolve the issue. There were some pretty funny ones, but it really helped when applying such things as xylem and phloem. Both of which are vascular tissue that conduct and distribute water, minerals, sugars, amino acids, and other organic products. This system allowed plants to grow tall and were able to provide support against gravity. Overall this week was a fun new look on where and how plants function.
