This is a picture of a sand dollar showing Radial Symmetry
    Radial Symmetry- This is the regular arrangement of body parts around a central axis. When an organism is radially symmetrical, you could cut from one side of the organism through the center, to the other side, anywhere on the organism, and this cut would produce two equal halves.


This is a fungi representing a Spore.  Fungi create hundreds of spores.
     Spore -  Spore is a reproductive structure, some of which are adapted for dispersal and surviving for extended periods of time in unfavorable conditions.


This picture of people helping weigh in my 4-H hog and shows Homeostatis.  Human bodies regulate imbalances in their body like sweating by lowering their body temperature.
     Homeostatis - Homeostasis is a point of balance or internal equilibrium.  It describes how the human body reacts to changes and keeps itself within certain parameters to ensure that it can function correctly. to regulate internal imbalances to sweating to lower body temperature.



This is a picture of a Crown of Thorns plant which is considered a CAM Plant.
     CAM Plant - CAM plants are able to absorb carbon dioxide from the air during night time and bind it to sugars during day time without losing aditional water.




This picture of the butterfly on our butterfly bush shows Mutualism.  The butterfly benefits from the nectar and the Butterfly bush  is able to be pollinated.
     Mutualism -  Mutualism is the symbiotic interaction between different species that is mutually beneficial to each one.




This photo of the tiger at Hovatter's show represents a Predator that in the wild exhibits Predation.
     Predation -  Predation occurs when one organism captures another and feeds on the captured organism.  One animal is the predator and the other that is eaten is the prey.


This photo shows leaves that have Phloem in them.
      Phloem Phloem carries the products of photosynthesis (sucrose and glucose) from the leaves to other parts of the plant.




This is a picture of maggots on an ear of corn.  The maggots are detritivores.
     A detritivore is an animal that feeds on dead organisms to breaksthem down into smaller molecules.





This ia a picture of a weeping cherry tree showing Cambium.
     Cambium cells are the building blocks for a tree.  They provide the physical structure that holds the tree up off the ground giving it its strength and flexibility.





These are peaches that can sometimes be sprayed with pesticides before being consumed to deter pests.  This demonstrates Biological Magnification.
     Biological Magnification, also called bioaccumulation -- is the process whereby certain substances such as pesticides or heavy metals move up the food chain and become more concentrated.
