BSC 1010 Lecture Notes - Lecture 1: Biosphere 2, Emergence, Systems Biology
Document Summary
The process of change that has transformed life on earth. Ex: shape of dandelion allows the seeds to fly and pollinate the different levels of biological organization: biosphere, ecosystem, communities, populations, organisms, organs/ organ system, tissues, cells, organelles, molecules emergent properties. Result from the arrangement and interaction of parts within a system. Ex: specific organization of molecules within the chloroplasts allows for photosynthesis to occur. if you mix all those molecules in a test tube, photosynthesis will not occur. The reduction of complex systems to simpler components that are more manageable to study. Ex: study structure of dna helps us understand inheritance systems biology. The analysis of the interactions among the parts of a biological system. To explore emergent properties, biologists complement reductionism with this. A leaf is thin and flat, maximizing the capture of light by chloroplasts. Four kinds of chemical building blocks in the chains of dna (a,g,c,t)
