Why is dissection an important part of a biology curriculum? Which animals and/or plants should be included in biological studies?

  Dissection is usually the process of disassembling and observing something to determine its internal structure and as an aid to discerning the functions and relationships of its components.  Dissection is important to the biology curriculum because the students need to understand what looks like inside the organisms, and see the muscle and tissue structures.  The variety of animals or plants need to be included in the biological study because the students have to know the different structures and functions of various kinds of organisms.  For example, mammals, reptiles, fishes, insects, birds, flowers, trees, and fungi can all be the part of biological study for dissection.
